ON5VL / OR0L Remote Station UBA-LGE

1. Before you start

The Remote Station lets members of the UBA-LGE section use the club transceiver (TRX) from home, with nothing more than a web browser. The TRX (a Yaesu FTX-1 with its SPA-1 amplifier, or depending on the setup an FTDX10, an FTDX101D / MP or an IC-7300) is at the club, connected to a PC. That PC is linked over the internet to the server remote.op0p.be, and that server is what you open in your browser.

1. You click a button on the dashboard (for example "20M").
2. The server passes the command on to the club PC.
3. The club PC sends the command to the TRX over its USB cable (the "CAT link").
4. The TRX changes band, and every connected member sees the new frequency.

The receiver audio travels the other way: it arrives in your browser, and the digital modes (FT8, RTTY, CW…) are decoded on the server.

2. Short glossary

Words that come up often in this manual and on the screen.

3. Logging in

1. Open https://remote.op0p.be in Chrome or Edge.
2. Enter your callsign and your password (given by a club administrator), then click Se connecter (log in).
3. The browser stays logged in for 7 days: when you reload the page, you go straight back to the dashboard.
4. Déconnexion (log out, top right) ends the session and forgets the browser: do this on a PC that is not yours.

• Listener callsigns (ONL…) can see and hear everything, but cannot transmit or change the power.
• After 15 minutes without any action, you are logged out. A warning appears one minute before, with a Rester connecté (stay logged in) button. This never happens during a transmission.
• The HELP button at the top right opens this manual in a new tab.

4. Guided first steps

Four "recipes" to get started. Each button is described in detail further on (sections 7 to 14).

4.1 Listening to a band

1. On the right, RX audio panel: click 🔊 Écouter le TRX (listen to the TRX). Set the Volume slider just below (it only affects you).
2. To change band or frequency you must have control: click Prendre la main (take control) at the top (if nobody has it).
3. Click a band, for example 40M, in the band row below the VFOs.
4. Choose the mode in the Mode panel on the left: LSB for phone on 40 m, USB on 20 m and above.
5. Tune the frequency: put the mouse over the digits of VFO A and use the mouse wheel. Each digit is set separately; the digit under the mouse goes up or down.
6. A station too strong? Lower the RF GAIN (RF front end panel) or switch ATT on. Lots of noise? Try DNR (noise reduction).

4.2 A phone QSO (SSB) with your own microphone

Your microphone (PC microphone, headset, USB microphone…) is sent to the TRX while you hold PTT: this is remote phone. It works in LSB / USB (and AM / FM on the FTX-1 and IC-7300). A headset gives the best result (no feedback, voice close to the microphone).

1. Take control, choose the band and LSB or USB. Afterwards, at each band change, the dashboard automatically sets LSB below 10 MHz and USB above (USB on 60 m); DATA, CW, AM and FM are left alone.
2. Open the TRX SSB page (SSB tab of the dashboard MODES row, or the front-panel SSB button); the microphone opens by itself (SSB configuration line; it only goes to the TRX with PTT). The first time, Chrome asks for microphone access: Allow (if access was refused, the MICRO button comes back to retry). Pick your microphone in the list if there are several.
3. The dashboard recognises the type of microphone from its name (headset, USB studio microphone, webcam, Bluetooth, built-in PC microphone…) and proposes a matching equaliser setting. Speak: the level bar must stay in the green, never in the red (SAT).
4. MICRO EQ: low cut, three adjustable bands (frequency, level, width), high cut, microphone gain, noise reduction. Listen to yourself on headphones with 🎧 MONITORING (Volume slider just below), then Enregistrer pour ce micro: these settings come back automatically whenever you use this microphone, on any PC.
5. Accord panel: TUNE, then check the SWR and the power.
6. Make sure the frequency is clear, then hold PTT (or the Space bar) and speak when the TX lamp turns red (about half a second on the first press, immediately on the following ones). Release to listen: while you speak, the TRX audio is muted on your side.

TRX equaliser (FTX-1, FTDX10, FTDX101): TRX EQ button in the same panel. These are the TRX's own PRMTRC EQ1 to EQ3 menus (PROC off, then PROC on). Take control, Lire le TRX, adjust, Essayer sur le TRX, then Enregistrer mon profil: your profile is put on the TRX whenever you take control, and the club setting is restored when you release it. Administrators can save the club setting.

4.3 An FT8 QSO

FT8 is the easiest mode to use remotely: everything is done with the mouse and the dashboard handles the sequence just like WSJT-X.

1. Take control. On the tab row, right of SYNCHRO, choose the TX call: the club callsign (ON5VL) or your own.
2. FT8 · FT4 · FT2 tab in the centre, FT8 button, then choose a band in the frequency list (e.g. "14.074 · 20m"). The TRX goes there by itself, in DATA-U.
3. Do a TUNE (Accord panel), then set a reasonable power (20 to 40 W is plenty for FT8).
4. Wait one or two 15 s periods: the stations heard appear in Activité de bande (band activity). CQ calls are in green.
5. To answer a CQ: click the station's callsign (dotted underline) or double-click its line. The TRX sends your call at the start of the next period.
6. Let it run: the sequence advances by itself (report, R-report, RR73, 73). The bar below the lists is red while transmitting, green while receiving.
7. As soon as the correspondent sends RR73, the « Enregistrer le QSO » (log the QSO) form opens already filled in: check it and save.
8. To call CQ yourself: click Tx6 (CQ). When a station answers, double-click its message: the QSO then runs by itself.
9. To stop everything: ■ Arrêter (stop) (or the Space bar).

4.4 Logging the QSO

1. After a digital QSO, the form opens by itself (FT8) or with the Log QSO button (JTTY, CW; also on the tab row, right of Logbooks); in RTTY, LOG ↵ on the QSO line logs it at once.
2. For a phone QSO: LOGS tab, type the callsign (the UTC time fills in by itself), click ⇩ TRX (take from the TRX) to copy the frequency and mode, then complete the reports.
3. Enregistrer le QSO (save the QSO) (or Enter). The QSO appears in the list. Under the club callsign, it is also uploaded to the online logbooks if the administrators have set that up.
4. To get your QSOs into your own logging program: Exporter ▾ → Mes QSO (.adi) (Export → My QSOs).

5. The screen at a glance

Top bar

The screen areas

1. Left column: Antenne (antenna), RF front end (receive), Mode, Filtres (filters), Station meters (measurements).
2. Centre, top: the two VFO displays (A / MAIN and B / SUB), the Step row (tuning step, VFO choice, SPLIT…) and the band row.
3. Centre, bottom: the tab row (no title above it): Modes (station activity log), FT8 · FT4 · FT2, SSB, RTTY, WSPR, JT65, JTTY, CW, SSTV (a mode tab opens that mode's page: TRX SSB, TRX CW, or TRX DIGI on that mode, with a title band at the top like the SSB page: TX call, then the page name for the tab, e.g. "ON5VL TRX FT8/FT4/FT2 · Remote Station · FT modes et contests", "TRX RTTY", "TRX WSPR"… The window no longer has mode tabs (the mode is chosen in the dashboard): in their place, like the SSB page, SYNCHRO (click again: back to the mode), TX CALL, the frequency of the chosen VFO (the page's TX VFO in dual receive, pink for VFO-B), the mode (orange if unsuitable: DATA expected in FT8, CW in CW…), then, as at the top of the dashboard, 👥 number of connected members (list on hover), your call and the control button (PRENDRE LA MAIN / LIBÉRER LA MAIN / "Main : call") — the same on the TRX SSB and TRX CW pages —, then the audio / decoding status and the UTC time, just left of "RETOUR"; each window — TRX SSB, TRX CW, TRX DIGI, logbook — reopens at the place and size it had when closed (TRX DIGI also stretches down to the bottom of the screen: taller message lists and band maps), and scrolls with the wheel when taller than the screen), then Logbooks (the dashboard opens on the logbook, which stays shown while the modes are in their own pages), the Log QSO button and Synchro.
4. Right column: RX audio (listening), DSP (noise reduction), Accord (tuner), TX (PTT and power).
5. Under the tabs: the QSO line (the station worked, its reports and the TX call), in the mode tabs and Synchro; it is hidden in the Modes and Logbooks tabs, where the logbook form (DÉTAILS QSO) has the call and reports. The TX call is on the tab row, right of SYNCHRO.

• Fold a panel: click its title (for example "DSP"); a second click opens it again. Your choice is remembered.
• Separate window: the ⧉ button of a panel opens it in its own window (section 11).
• Below the band row, a message line shows confirmations and refusals (« Prenez la main… » (take control…), « PTT refusé : … » (PTT refused)).

6. Taking and handing over control

• Only one person has control (operates the TRX); everybody sees and hears the same thing.
• Prendre la main (take control, top bar): possible if nobody has it. The button then becomes Libérer la main (release control).
• If someone already has it: open the 👥 panel and click Demander la main à … (request control from …). The operator receives the request (their panel opens) and can click Passer la main à … (hand control to …). You can also send them a message in the chat.
• Fairness: if the operator has had control for 45 min and another member has requested it (request valid 15 min), the operator is warned; control passes to the requester 2 min later, never in the middle of a transmission (at its end). With no pending request, you can keep control as long as you are active (released after 15 min without any action).
• 🔔 Mise à jour X.Y.Z (administrators, top right, yellow button with a ringing bell): a new Remote Station version is published. Click: what is new, then Installer maintenant — the VPS downloads the official release, checks its fingerprint and installs it (station off for about one minute, members warned); then Ctrl+F5. The very first time, update by hand (see the admin guide).
• 📊 STATS (administrators, top right): usage statistics page — time with control and time connected per callsign, transmitting, sessions, days, QSOs, bands and modes, chart per day, weekday × hour map (Belgian time), session log (who, when, how long, bands, modes, TRX), CSV export for Excel; period and callsign to choose. Recorded minute by minute in logs/usage-YYYY-MM.jsonl; before this version, durations estimated from the control log.
• One account, one operator: your account can be open in several tabs or on several devices on the same network (same internet address). A login from another address closes the sessions open elsewhere (they will have to type the password again) and administrators are told: do not lend your account.
• Countdown: next to Libérer la main, ⏱ 14:58 gives the time left before control is released (and the session closed) without any action; each setting or transmission resets it to 15 min; orange under 2 min, « ⏱ en émission » during a transmission. When a member is waiting for control (fairness), it turns into a red badge ⏱ main → ON4XXX dans 1:45.
• When you leave, click Libérer la main. With no action for 15 minutes, control is released automatically.
• The top-bar button shows Main occupée (control taken) when someone else has it, and Prendre la main ici (take control here) if you already have it in another tab or another browser. An administrator sees Reprendre la main (take back control): they can take it back if needed, after confirmation.
• Without control, the commands are greyed out and a message reminds you « Prenez la main » (take control).
• Following the operator (for remote training): 👁 Suivre (follow) button just after the digital-mode tabs. When on (green), your screen shows the same tab as the operator in control (RTTY, FT8, CW…) and changes along with them. Clicking another tab yourself stops following; a click on 👁 Suivre starts it again. This button is not shown to the operator in control. It switches on by itself when you arrive while another member has control, and each time another member takes control afterwards.

7. Operating the TRX

All the commands in this section require having control, except listening and the volume. They act on the real club TRX and everybody sees the result. Some exist on only one TRX: they are greyed out or absent on the others. When a button is lit (coloured), the function is on; a click switches it off.

7.1 The VFO displays

At the top centre, two displays: VFO A (MAIN) on the left and VFO B (SUB) on the right. They look like the display of the TRX.

7.2 Step row and band row

Below the VFO displays.

The grey line below the bands is a reminder of useful actions; the message line just below it shows confirmations and refusals.

7.3 Left column

Antenne (antenna)

RF front end (the receiver input)

Mode

Below the buttons, « Mode appliqué à VFO A » (mode applied to VFO A) shows which VFO changes mode (the one chosen with A / B).

Filtres (filters)

Station meters (measurements, mostly useful when transmitting)

7.4 Right column

RX audio

DSP (signal processing)

Accord (tuner)

TX

7.5 Operating SPLIT (transmit and receive on two frequencies)

SPLIT is mainly used for a DX expedition listening away from its own frequency ("UP 5", "listening 14 200 to 14 210"). You listen to the DX on VFO A and transmit on VFO B.

1. Set VFO A to the DX frequency, in the right mode. Check that RX is green on VFO A.
2. Click A → B: VFO B takes the same frequency and mode.
3. Set the transmit frequency on VFO B with the mouse wheel on its digits, for example +5 kHz for "UP 5". On the FTX-1, the wheel on VFO B does not change the side you are listening to: you stay on A.
4. Click SPLIT (or TX on the VFO B display). The TX lamp and the glowing frame move to VFO B; the reminder shows « Émission sur B » (transmit on B).
5. Listen to the DX on A; hold TXW (or W) to listen to the pile-up on your transmit frequency. To call, PTT: the transmission goes out on VFO B (digits in red). On release, back to receive on A.
6. To finish: click SPLIT again (or TX on VFO A). The TX lamp goes back to A.

8. Listening

• RX audio panel → 🔊 Écouter le TRX, then set your Volume. Everybody can listen, even without control.
• The audio arrives with a small delay (a fraction of a second): this is normal over the internet.
• If you hear nothing: check your PC volume, then the Station lamp. The club's Station page must have audio enabled (section 18). The message below the button says what is missing.
• AF LEVEL and SQUELCH act on the TRX itself, for everybody.
• No more audio, a silent waterfall with only a hum at the far left, and the orange « Plus de son du TRX » alert: the TRX USB sound card has frozen. A station manager restarts it remotely (Relancer la carte son button), otherwise the TRX must be switched off and on at the club (section 18).

9. Transmitting and safety

1. Have control and an account allowed to transmit (ONL listeners cannot).
2. Be in a band authorised for your licence.
3. After a band change: TUNE, then check the SWR. A reminder flashes to the right of the 70CM key until the TUNE (on 2 m and 70 cm there is no tuner: only "check the SWR"). The SPA-1 tuner only works on HF and 6 m, and the amplifier must be switched on.
4. Set the power (TX panel).
5. Transmit: hold PTT (or Space), or use the transmit buttons of the digital modes.

Transmitting is only possible if the administrators have enabled it on the server.

9.1 Phone and contests: the TRX SSB page

SSB tab of the dashboard tab row, or SSB button of the front-panel MODES line: a separate page (address /ssb), attached to the page that opened it (same connection, same control), like TRX CW (RETOUR button top right: close the page and go back to the opening page, also in TRX CW); with control, the TRX goes to LSB (below 10 MHz) or USB if it was not already in SSB. At the top: TRX frequency and mode (orange outside LSB / USB), who has control (PRENDRE LA MAIN), and on the far right RETOUR (no RX / TX lamp: the PTT turns red while transmitting). Next to PRENDRE LA MAIN: 👁 SUIVRE L'OPÉRATEUR (remote training), the same as on the dashboard, the TRX DIGI page and the front panel: your pages show the same mode and markers as the operator who has control, and the header shows the mode they are on ("Main : ON4LUC · sur FT8"); greyed for the operator who has control. Just below, phone as under the front panel: the large PTT button (hold, or the space bar when the cursor is not in a box; it turns red as soon as the TRX transmits, also during a voice memory) and the SSB CONFIGURATION line (MICRO EQ, mic level, TRX EQ, then the TRX mic settings GAIN MICRO, NIVEAU PROC, VOX (no PROC button: NIVEAU PROC at 0 = PROC off ("OFF"), above 0 the PROC switches on by itself — only in SSB or AM on the TX VFO; TRX EQ is green when the TRX equaliser is on, on a black background when it is off; MIC EQ is switched on or off in the TRX EQ window), and Profil de … on the far right: all on one line; sound Entrée (input) and Sortie (output) in yellow, 🎧 MONITORING and its volume, then 🔊 ÉCOUTER LE TRX: the TRX audio in your headphones (green while listening; click again: stop) and its Volume TRX (the same slider as in the dashboard; the "Volume" next to MONITORING is that of your own voice)). The microphone opens by itself when the page opens (no more MICRO button; it only comes back if the browser refused the microphone); the chosen output is also used to listen to the TRX; the voice goes through the opening page's connection, same safety as the front-panel PTT. On the left of the page (and of TRX CW), the band map: DX cluster spots of the TRX band, phone part (TRX SSB) or CW part (TRX CW), red line = TRX frequency; call in green, struck in red if already in the contest log on this band, greyed after 20 min; − / +: narrower / wider range, wheel: scroll, double-click: back; click on a spot: the call in the page and, with control, the TRX on its frequency (LSB / USB or CW). In the TRX DIGI page, the band map is also on the left. Below the phone line, the two VFOs box (two-VFO TRX, also in TRX CW, below the keyer): without SPLIT, only the active VFO; in SPLIT, VFO A and VFO B side by side with frequency and mode, RX in green on the receive VFO, TX in red on the transmit one (red background while transmitting); SPLIT ON / OFF (receive on one VFO, transmit on the other; the dashboard shows the same SPLIT), A ⇄ B (swap), A → B (copy), B = A −1 / +1 / +2 / +5 / +10 kHz (VFO B next to VFO A, SPLIT set automatically), and a kHz box per VFO to type a frequency (Enter). To transmit on your frequency while listening elsewhere: your frequency in VFO B (transmit), the listened frequency in VFO A (receive), SPLIT ON. With control, not while transmitting. The title starts with the TX call (callsign used on the air, e.g. "ON5VL TRX SSB" or "ON6DP TRX SSB"): without a contest, the one chosen in the form's TX CALL box; in a contest, the station's (TX call chosen with control). Same in TRX CW. Next to the title, the TX CALL list (also in TRX CW; the TRX DIGI page has it in each mode's bar): with control, the callsign used on the air and for the QSOs logged (ON5VL, OR0L, OP0P of the station, or your own), hence in ADIF and Cabrillo exports; the logbook form follows it.

VFO screens: the same as the dashboard ones (RX / TX, BW, SFT, S-meter, frequency, filter, dial, audio spectrum, RIT / XIT, mode, ATT, NB, NOTCH, AGC…), copied live; a click or the mouse wheel on a screen acts as in the dashboard (wheel on a frequency digit, on BW, on the badges…); a click on the filter, dial or spectrum enlarges it in the middle of the screen, as in the dashboard (click or Esc to close). Just below: SPLIT, A ⇄ B and A → B.

Both VFOs, DUAL RX and stereo listening (TRX with two receivers: FTDX101, IC-7760, FTDX5000, FTX-1): in the middle of the VFO box, under SPLIT, DUAL RX ON / OFF (with control) switches both receivers on; both VFOs are then shown side by side, VFO A · MAIN in green and VFO B · SUB in pink. 🎧 STÉRÉO (FTDX101 and FTX-1, which send their two receivers separately): headphone listening with VFO A (MAIN) in the left ear and VFO B (SUB) in the right ear ("🎧 G" / "🎧 D" in the VFOs); it switches DUAL RX on if needed (with control) and starts the dashboard TRX listening. Everyone chooses stereo for themselves (no control needed); click again = both receivers mixed in both ears. FTX-1: dual receive only if one VFO is above 118 MHz.

Band map (phone spots from the DX cluster) on the left; with a TRX that has two true receivers (IC-7760, FTDX101, FTDX5000…), a 2nd map on the right: the VFO-A (MAIN) band on the left, the VFO-B (SUB) band on the right. Click a spot: the call goes into the form and, with control, that VFO goes to its frequency.

Without a contest ("— pas de contest —"): LOG DU QSO box, the logbook entry form as in the Logbooks tab (call, UTC date and time, ⟳ Maintenant, frequency from the TRX, mode USB or LSB only (the TRX's, otherwise LSB below 10 MHz and USB above), ⇩ TRX, RST, TX call, QO-100, name, QTH, locator, power, remark, IOTA / WWFF / POTA / BOTA / LLOTA references, ＋ Ma référence) and ENREGISTRER LE QSO: the QSO goes to the general logbook. Dupe questions appear in this page only; the dashboard form is left alone. Below the form, down to the bottom of the page: the latest phone QSOs outside contests (SSB, LSB, USB) from the general logbook, newest at the top (date, time, call, band, frequency, reports, name, QTH, country, TX call, operator); LOG SSB box like LOG RTTY: a click on the LOG SSB ⤢ title enlarges it in the middle of the page (Esc: back); EXPORTER ▾: Mes QSO SSB (.adi) = your phone QSOs outside contests, ADIF (.adi)… = with filters (TX call, operator — all operators for an administrator —, phone outside contests or all phone, from / to dates). In a contest, the page only shows the chosen contest's QSOs (log on the right: UTC, band, call, sent report Env. then the sent exchange TX # (serial number, zone… per the rules), received report Reçu then RX #, DXCC, Pts = QSO points per the rules (0 for a dupe, struck through), contest name); they are also in the general logbook, with the contest name in the Contest column. Correcting a QSO: a click on its callsign in the contest log opens its details just below (over the following QSOs): call, UTC date and time, frequency, mode, reports, TX # / RX # exchanges, name, contest, remark; ENREGISTRER corrects the QSO in the general logbook, SUPPRIMER removes it (after confirmation), FERMER or Esc. A member only corrects their own QSOs (an administrator, all).

Propagation (without a contest, right of the QSO list): solar flux SFI, sunspots, A and K indices, X-rays, solar wind, Bz, geomagnetic field, noise (green = good, yellow = fair, red = poor; hover: explanation), then the calculated HF conditions per band group, day and night — the column matching the current time at the station (day or night at the club locator) is highlighted — and the VHF state (aurora, Sporadic E in Europe). Source: hamqsl.com (N0NBH, NOAA data), read by the server every 30 minutes.

• Indicatifs probables (likely calls): while typing the start of a call (2 characters or more), the known calls containing it: those of the contest log, then the Super Check Partial list (MASTER.SCP, active contest calls, downloaded weekly by the server), green if not yet in the log, struck through if already worked on the band; click to put it in the call box. Empty box: the stations spotted in SSB on the TRX band (DX cluster), newest first; click puts the call and, with control, the TRX on its frequency.
• The contest log (right) runs down to the bottom of the page; every QSO is also in the general logbook, Contest column.
• Spot cluster (box next to LOG ↵, also under the "LOG DU QSO" form without a contest, in the TRX CW and TRX DIGI pages and in the logbook): ticked, each QSO when it is logged is also spotted on the band-map DX cluster (call, frequency, mode and contest, or "TNX QSO"), under your operator call (your account, e.g. ON6DP) — not the TX CALL. Same setting in every page. Only for accounts allowed to transmit; at most one spot every 20 s and 30 per hour; the result is shown ("Spot envoyé au cluster de ON6DP…" or the reason for a refusal).
• Enter key (ESM): RUN (you call CQ): empty box → voice memory T1 (CQ); call typed → cursor in Reçu (say the exchange on the microphone); received exchange typed → QSO logged, then T3 (TU / QRZ) if recorded. S&P (you answer): call → T4 (your call); received exchange → QSO logged.
• 🗣 Config. Macros (next to the Voice memories title, also without a contest): 8 standard messages in English or French, spoken by a natural synthetic voice of the server, with your TX call spelled in the phonetic alphabet.
  • Top line (yellow labels): Langue (one message set per language; in French, messages for the Coupe du REF), Voix, ▶ Écouter (blue button: message T1 played on your PC, nothing transmitted), Vitesse (100 to 320 words per minute; 170 to 200 gives a contest pace) and Espacement des lettres (short pause between the spelled words of the call, 0 to 300 ms).
  • Voices: "Voix Kokoro (les plus réalistes)" group (US and GB English, male and female — George, Michael, Emma, Bella…; in French: Siwis) and "Voix Piper" group (in French: Tom, Gilles, Pierre, Jessica, Siwis). Installed on the server by an administrator: Kokoro with sudo bash /opt/remote-station/deploy/install-kokoro.sh, Piper with install-voix.sh. espeak-ng voices (too choppy) are no longer offered.
  • {CALL} = the spelled TX call: in English ON6DP → "Oscar November Six Delta Papa"; in French "Oscar Novembre Six Delta Papa", digits said in French (six, eight and five said in full, even before a letter), months said in French, abbreviations the French way (CQ = "cé kiou", QRZ, QSO); in English the Z of QRZ is said "zed".
  • Prononciations box: "word=said as", one line per word (e.g. Romeo=Roméo), to fix a mispronounced word, kept per language.
  • In English: T1 CQ contest, T2 CQ, T3 Thank you / QRZ, T4 your call, T5 Again please, T6 Your number again, T7 Is this frequency in use, T8 73. Texts and names can be edited.
  • Tick the memories wanted then GÉNÉRER: the server makes the voice once and keeps it as memory T1 … T8; then F1 … F8 transmit it at once, without waiting. When the TX call changes, these messages are remade by themselves with the new call (or at transmit time, 1 to 3 s that time); a memory re-recorded with the microphone is no longer remade. ✕ Fermer closes the box without generating; settings are kept.
  • Level: messages are made at the level of a microphone voice (about −18 dB), with 0.4 s of silence at the start (switch to transmit) and a clean end; on the air, switch the speech processor (PROC) off for these memories and adjust VOICE TX TX LEVEL if needed: an over-driven synthetic voice sounds "robotic".
• Voice memories F1 … F8 = your memories T1 … T8 (also without a contest: they then sit above the logbook form; texts are edited in “Config. Macros”) (VOICE TX: recorded with your microphone, MENU → VOICE → REC on the front panel), duration under the name; the key turns red while transmitting, Esc stops it. The rest is said on the microphone with the PTT of the page that opened the SSB station page. Same safety as phone.

10. Operators and chat

• The Opérateurs (operators) panel opens and closes with the 👥 button in the top bar. A red dot on 👥 means a new message. When another member's message arrives, 👥 blinks (until the panel is opened), the author's callsign blinks in the list for 20 s, the message shows at the bottom of the screen and a beep-beep sounds; 🔔 next to « Envoyer » turns the beep off or on (🔕 = off), kept in this browser.
• ON6DP, ON4LUC and ON5VL (the station's own account) are never logged out for inactivity (only with « Déconnexion »); control is still released after 15 min without any action. Server setting idleExempt.
• It shows the connected members and who has control.
• Chat: type a message in « Message aux connectés… » (message to connected members) then Envoyer (send) (or Enter). All connected members see it. Messages are not kept after a server restart.
• The Demander la main à … and Passer la main à … buttons appear there when relevant (section 6).
• The Modes tab (first tab in the centre) is the station log: logins, control taken and handed over, transmissions (frequency, mode, power, duration), tuning, safety cuts, station online, TRX connected…

11. Layout and separate windows

• ⧉ button at the top right of a panel: the panel opens in its own window, to place wherever you like (on a 2nd screen…). In that window, ⧉ Ramener (bring back) puts it back in the dashboard.
• The whole dashboard in its own window: ⧉ Fenêtre button in the top bar. The dashboard reopens in a window of its own, without address bar or tabs, that you place and size wherever you like; its position and size are remembered for next time. The original tab shows « Dashboard ouvert dans sa fenêtre » (with a button to bring it back or to the front). Chrome must allow pop-ups for remote.op0p.be.
• Install it as an app (Chrome, Edge): ⤓ Installer button in the top bar (or the install icon at the right of the address bar). Remote Station then gets its desktop icon and Start-menu entry and always opens in its own window. The button disappears once installed; to uninstall: ⋮ menu of its window → Uninstall.
• On the front-panel page (/ftdx101), band maps on each side of the TRX: VFO A's band on the left, VFO B's on the right (cluster spots around the VFO frequency; − / + (or Shift + wheel): range 5 to 200 kHz, or the whole band of the VFO (default: all the band's spots); when the calls do not fit, a scrollbar appears and the wheel scrolls the list (the VFO is kept in view, except for 15 s after you scroll by hand); in SPLIT both maps switch to ±10 kHz around their VFO; click a call: that VFO goes there; under the band name, ALL · FT8/4/2 · SSB · CW · RTTY shows only the spots of that mode, click again for all).
• On the front-panel page (/ftdx101), the digital modes have their own page: 📟 Numériques button in the top bar (✕ Fermer closes it).
• The ⧉ button to the right of the tabs opens all the digital modes in a separate window. RETOUR (bring back into the dashboard) (or Ramener ici (bring back here) in the dashboard) puts them back.
• The Space bar (PTT) also works from a separate window.
• The layout is remembered: on the next load, the windows reopen in place if Chrome allows pop-up windows for remote.op0p.be (icon at the right of the address bar → Always allow).
• Collapse a panel: click its title (or Enter when the title has focus); a second click reopens it. Remembered in this browser.
• Size of the whole dashboard: Auto 100 % menu in the top bar (section 5), from 50 to 200 %.
• Drag handles (double-click: original size, remembered in this browser): under the waterfall (height of the waterfall and lists), between the two FT8 lists and between the two RTTY decoders (widths), on the left edge of the band map (its width), on the right edge of the logbook column titles (column widths).
• Band map: on a 1920 × 1080 screen or larger, it is a column of its own, far right, full height (the RX audio / DSP / Tuner / TX column sits just to its left). It only appears on tabs with spots (FT8 · FT4 · FT2, JT65, RTTY, WSPR, JTTY, CW). On a smaller screen it stays at the right edge of the centre window.

11.1 FTDX101 front panel (separate page)

Address: https://remote.op0p.be/ftdx101. The FTDX101MP front panel, where each key and knob does the same as on the TRX, with the digital modes below it (FT8, RTTY, WSPR, JT65, JTTY, CW, SSTV, Synchro) as in the dashboard. Same login, same Prendre la main button, same safety rules. Only useful when the FTDX101 is the TRX in service.

FTDX5000 (trial): https://remote.op0p.be/ftdx5000 (digital modes: /ftdx5000/digi.html). The picture is the front panel drawn by Yaesu's PCC-5000 software. Its display follows the radio live: VFO-A frequency, clarifier, MAIN and SUB ANT / ATT / IPO / AGC values, TX, mode, BUSY, NAR, FAST, LOCK, NB, MONI, KEYER, BK-IN, PROC, TUNER, HI-SWR boxes; VFO-B display and the small filter displays (BW, SHIFT). Under the front panel: on the left, an enlarged replica of the display, laid out like the radio's: VFO-A (MAIN) at the top, the VFO-B S-meter bar in the middle, VFO-B (SUB) at the bottom; for each, every ANT / ATT / FLT / IPO / R.FLT / AGC value is listed and the radio's one lights up in yellow, and the status grid on the right (TX, LSB, USB, CW, BUSY, AM, FM, NAR, FAST, RTTY, PKT, LOCK, NB) lights up in white (TX in red); top strip: VFO-A (large) and VFO-B frequencies, clarifier, active VFO name lit; FLT (VRF / μ-T) and R.FLT stay dark (no CAT command), on the right the page screen (meters, frequencies, received-audio scope; CENTER, SPAN, 3DSS, MONO, MULTI, EXPAND, HOLD keys at the bottom; no DISP key on the FTDX5000: normal layout, even if another front panel was left in « enlarged filters »). The scope and waterfall come from the received audio sent by the Station page: nothing in simulation without an audio input chosen. The MENU key opens the FTDX5000 settings (RF POWER, MIC GAIN, PROC, MONI, VOX GAIN / DELAY, KEY SPEED, CW PITCH, NB, DNR, SQL, STEP DIAL); its numbered menu 001-176 stays at the club. Two receivers: A / B keys = VFO of the main dial, CLAR/VFO-B knob = VFO-B frequency (or clarifier offset with RX CLAR / TX CLAR), RX under the VFO-B display = dual receive, TX = transmit on VFO-B (SPLIT). Under each VFO, the knob sets SHIFT (centre) and WIDTH (ring); MIC ◎ RF PWR, SPEED ◎ PITCH, VOX ◎ DELAY, MONI ◎ PROC, NB ◎ SQL and AF ◎ RF GAIN as on the radio. Keys without a CAT command (VRF, CONT/APF, R.FLT, TXW, memories…) show an explanation. Picture: Yaesu PCC-5000. The function screen (RF POWER, MIC GAIN…) opens and closes with the front-panel MENU key or the MULTI box at the bottom right of the screen; the keyboard Esc key also closes it. The ANT, ATT, IPO, R.FLT and AGC keys act on the VFO chosen with the A / B keys (VFO-A = MAIN, VFO-B = SUB), as on the radio. A ► B (copies VFO-A into VFO-B) and A ⇄ B (swaps the two VFOs) keys, as on the radio. In TX, the TX indicator under the display becomes a bright red box with bold white text. CONT/APF of each VFO: CONTOUR ON / OFF (in CW: APF ON / OFF; CO command of the manual, only one of the two at a time), key lit when on; press for at least 1 s: CONTOUR frequency (100 – 4000 Hz, − / + or mouse wheel); also in the dashboard for both VFOs. R.FLT (roofing filter, RF command of the CAT manual): the R.FLT key steps AUTO → 15 kHz → 6 kHz → 3 kHz → 600 Hz → 300 Hz (MAIN; 600 and 300 Hz are optional filters); the display lights the filter in use for VFO-A and VFO-B (in AUTO too), the screen's R.FLT box and the dashboard show and set it (VFO-B: AUTO, 15k, 6k, 3k).

FTDX10: same idea at https://remote.op0p.be/ftdx10 (digital modes: /ftdx10/digi.html). The FTDX10 has a single receiver: one S-meter, VFO-A large and VFO-B small (greyed), ATT / IPO / R.FIL / AGC cells, the filter (WIDTH, NAR, R.FIL 12k / 3k / 500 Hz, IF SHIFT, NOTCH, CONTOUR) and the audio scope; no MAIN / SUB, DISP, MONO or dual receive. BAND opens a band table on the screen; A/B swaps the VFOs (hold: A → B); STEP/MCH = fast tuning; FINE = 1 Hz per notch; CONT/APF = CONTOUR, or APF in CW; VOX/MOX: click = VOX, hold = MOX; the FUNC knob adjusts the function shown right of VFO-B (click the knob or that box for the FUNC menu).

FTX-1 (Field head with the Optima amplifier): https://remote.op0p.be/ftx1 (digital modes: /ftx1/digi.html). Same screen as the FTDX101 front panel (two receivers), but as on the radio the SUB is on the left and the MAIN on the right; cells ANT, ATT, IPO, NAR, AGC; bottom row CENTER, 3DSS, MULTI, SCOPE (scope settings), SPAN, SPEED. Keys: BAND, N/W MODE (short press: NARROW ⇄ WIDE on the active receiver; hold 1 s: mode list), SPLIT (FTX-1 virtual split), CLAR, DISP, BACK, FINE/FAST, LOCK; BUSY/TX SUB / MAIN LEDs. Knobs: main dial, SUB DIAL (VFO B frequency; click: active VFO MAIN ⇄ SUB, in dual receive only), FUNC (hold 2 s: the TRX FUNC screen, 3 pages; turn FUNC to move the orange frame, push FUNC to adjust the item, push again when done; hold 2 s to exit), SUB and MAIN AF/RF. Frequencies with the last 3 digits (Hz) smaller and filters drawn as on the radio (white outline, grey inside). SPAN (5 kHz to 1 MHz) is read from and sent to the radio; the radio's scope data is not available over CAT, so in CENTER, when the SPAN is wider than the received audio, the page shows that audio (3 kHz) across the full width with its own frequency scale (« son reçu : 3 kHz » top right); in CURSOR / FIX it shows the whole SPAN window, the green ▼ can be anywhere and follows the mouse when dragging with the left button; the right button (click or drag) sets the red TX line on the other VFO and turns SPLIT on if needed; in SPLIT, as on the radio: in CURSOR / FIX the page uses the real SPAN window, fixed, with red ▼ at the TX frequency and green ▼ (listening) moving across it with the main dial; in CENTER only the red TX line moves; a « SPLIT » badge (black on white, blinks twice) appears next to FAST / FINE; click (or drag) on the spectrum or waterfall: that VFO goes to the clicked frequency (hover shows it), as when touching the radio's screen. ATT / IPO of the SUB: the FTX-1 CAT only reads and sets them on the side in use (« — » until SUB has been the active side). Page 3 (FM/C4FM): SQL TYPE in all modes, TONE FREQ and DCS in FM, DTMF screen (memories 1 to 10, read and editable). RADIO / CW / OPERATION / DISPLAY / EXTENSION / APRS SETTING and APRS BEACON menus, laid out as on the radio, are for administrators only (ON6DP, ON4LUC): values read from the radio and re-read every 8 s, click a setting to see all its values, then − / +, wheel or FUNC; DATE&TIME can be set from your PC clock; PRMTRC EQ items open TRX EQ. Still locked even for administrators: CAT-1 / CAT-3 link, MOD SOURCE, USB MOD GAIN, RPTT SELECT, PC KEYING, CW MEMORY 5, TX equaliser (profiles), AUTO POWER OFF. Band maps in the same order as the screen: VFO-B (SUB) on the left, VFO-A (MAIN) on the right. 🎧 Stereo MAIN | SUB: DUAL RX, MAIN in the left ear and SUB in the right ear (the FTX-1 sends both receivers in stereo over USB).

IC-7300: https://remote.op0p.be/ic7300 (digital modes: /ic7300/digi.html). Single receiver, same screen as the FTDX10 with Icom settings: ATT, P.AMP, FILTER (FIL1/2/3), AGC; the drawn filter follows FIL1/2/3 and the TWIN PBT (centre = inner PBT, ring = outer PBT, click = CLR). MENU = the IC-7300 MENU screen (2 pages; VOICE becomes KEYER in CW, DECODE in RTTY), FUNCTION = Icom function screen, pushing MULTI = MULTI menu of the mode (RF POWER, MIC GAIN, COMP, MONITOR; CW: KEY SPEED, CW PITCH), click the mode on the screen to change it, M.SCOPE = expanded scope, QUICK = QUICK MENU (BAND, SPLIT, A=B…), EXIT closes it, ▼ ▲ = previous / next band, A/B swaps the VFOs (hold: A = B), TRANSMIT = latched TX.

IC-7760 (trial): https://remote.op0p.be/ic7760 (digital modes: /ic7760/digi.html). Photo of the control head (Icom). Screen as on the radio at power-on: on the left the ANT, P.AMP, ATT, DIGI-SEL, IP+, AGC, COMP key column (selected receiver; click to change; cyan bar on the key's right edge = on, grey = OFF, as on the radio; hold AGC for 1 s: AGC time-constant table (SSB, CW, RTTY, PSK, AM, FM × FAST, MID, SLOW) — the current mode / FAST-MID-SLOW cell is highlighted, the main dial (or the wheel on the cell) changes it, DEF restores the factory value, ↩ or EXIT close it; other modes are set when the radio is in them (until read, their cells show the factory values); hold DIGI-SEL for 1 s: MULTI column with DIGI-SEL selected — the MULTI knob tunes the DIGI-SEL (marker on the slider), a short click on an already selected cell turns its function ON / OFF (DIGI-SEL, COMP, MONITOR); in SSB the COMP cell only shows when COMP is on; in CW / RTTY / PSK the 7th key becomes 1/4: main dial 4 times slower, 25 Hz per notch). At the top of each half: bar S-meter (S · 1 · 3 · 5 · 7 · 9 · +20 +40 +60dB; Po 0 – 200 W in TX) and SWR below, as on the radio's main screen; the needle meter (S, Po, SWR, COMP) is in the right-hand small screen with « MET Po » and the date; the SUB DISP key cycles the needle meter, the filter ([MAIN] [BW] [SFT], FIL, SHARP / SOFT, MN keys) and band keys (TWIN-PBT: the outer ring sets the width (BW), the inner knob the shift (SFT) of the selected receiver; a BW / SFT box with the filter drawing and the passband edges in orange shows for 2 s on the main screen, on the left for MAIN and on the right for SUB; BW and SFT are the same in the header, the small screen and the box while turning; the small white LED right of the knob lights as soon as the passband is shifted or narrowed; pushing the knob (CLR) centres both and turns the LED off; needle meter: S, Po, SWR, COMP, ALC and Vd as on the radio; clicking it opens the METER window — Po, SWR, ALC, COMP, Vd or Id = what the needle shows in TX (“MET Po”…), Multi-function = S/Po, ALC, COMP, SWR and Id bars in the small screen (clicking the bars: METER window with OFF = back to the needle meter); the back arrow closes the window; the filter: grid, spectrum and waterfall of the received audio inside the passband, passband edges in orange, e.g. 0 · 1500 · 3000 for 3.0 kHz; touching the small screen shows FIL, SHARP / SOFT and MN, hidden again after 10 s) (1.8 … 50, GENE, F-INP) of the selected receiver. Click ANT, BW or SFT at the top of a VFO: settings window for that receiver — ANT 1 to 4 and RX ANT; FIL1 / FIL2 / FIL3 and width (main dial, wheel or − / +); SFT: both PBT together, CLR to centre. If the screen shows « TRX muet : RF deck alimenté et relié à la tête ? », the radio does not answer: at the club, check the RF deck (the large box) is powered and connected to the control head, then restart the IC-7760 (it shows « The RF deck is not detected »). RFG (orange): that receiver's RF gain is not at maximum — turn the outer ring of AF-RF/SQL (usually around 12 o'clock) until RFG disappears. Front-panel LEDs: POWER blue when the radio is linked to the station, small white LED in TUNER when the tuner is on, in NB, NR, APF/TPF and NOTCH when the function is on (selected receiver), blue LED in VOX/BK-IN when VOX (phone) or BK-IN (CW) is on; TX/RX next to AF-RF/SQL: green while receiving (SUB: with DUAL-W), red for the transmitting VFO, the other stays green if it receives (SPLIT or DUAL-W). Click a kHz or Hz digit of a frequency: small ▼ above it — the main dial and the wheel (over the frequency) then change that digit (100 kHz, 10 kHz, 1 kHz…); click the same digit again: ▼ removed; hold the MHz digits 1 s: ▼ on MHz (1 MHz steps). Click the MHz digits: BAND STACKING REGISTER (1.8 … 50, GENE: last frequency and mode used on that band, remembered by the page in this browser) and F-INP: the radio's keypad (PC keyboard works too; orange « F-INP » next to FIL while typing) — « 14.074 » then ENT; SPLIT puts the typed frequency on SUB and turns SPLIT on; MEMO is not remote. Click a VFO's mode: MODE window (SSB — LSB below 10 MHz, USB above —, CW ⇄ CW-R, RTTY ⇄ RTTY-R, PSK ⇄ PSK-R, AM, FM, DATA = USB-D1 even below 10 MHz); it closes as soon as a mode is chosen. ↩ or EXIT close these windows. Scope: a click opens a magnifier (×3) around the clicked point, a click inside it puts that scope's VFO on that frequency, a click elsewhere closes it; mouse button held and dragged: the frequency follows the mouse. DUAL-W also sets the scopes to DUAL; without DUAL-W, one scope (the current VFO's) and the radio's single-scope screen: needle meters at the top (SUB greyed), larger frequencies, filter in the small screen. With two scopes: bar S-meters and the needle meter in the small screen. MULTI column in CW: RF POWER, KEY SPEED, CW PITCH, DIGI-SEL, SIDETONE; in RTTY / PSK: RF POWER, DIGI-SEL, MONITOR., then MAIN on the left and SUB on the right, each with its ANT · BW · SFT header (AN / MN), « MET Po », its meter, TX and power, « VFO [mode] [FIL] » (click the mode: mode table; FIL: next filter) and the large frequency; DUAL-W / SPLIT in the middle; below, the SPECTRUM SCOPE: the radio's own scope (sent over CI-V) — in DUAL, MAIN on top and SUB below, each with its waterfall, an orange frame around the active VFO's one, « CENTER MAIN » / « FIX SUB »; click in a scope = that VFO to the clicked frequency (without the radio's scope: the received audio). Row <MENU1> · SPAN (EDGE in FIX) · HOLD · CENT/FIX · MAIN/SUB · DUAL · EXPD/SET: blue keys as on the radio (front-panel MENU key: the radio's MENU screen — SCOPE, AUDIO (M.SCOPE screen), VOICE / KEYER / DECODE, METER (MULTI-FUNCTION METER under the shortened scope: S, Po, ALC, COMP, SWR, Id, SUB S, Vd — TEMP cannot be read over CI-V; P-HOLD: peak hold; the M.SCOPE key cycles “scope + MULTI-FUNCTION METER” → “METER only” → “scope only”; under the waterfall, frequencies in MHz in CENTER too (14.28 · 14.30 … for ±50k), spacing following the SPAN, and ±SPAN at the top left and right; MAIN / SUB keys: the white curved band above the main dial shows the selected receiver; red NOTCH box right of SFT in the header of the VFO whose manual notch is on; scope header as on the radio, with the settings read back from the radio for the selected receiver: M (Max Hold), S, T (Scope during Tx), HOLD (white when on), speed ▸▸▸ / ▸▸ / ▸ (FAST / MID / SLOW), RBW and VBW (bright blue when RBW is not WIDE or VBW is WIDE), CENTER / FIX / SCROLL, MAIN (red) or SUB (blue), “Grid 5k/10dB” (grid step); 1-second press on <MENU1>: <MENU2> row — REF (mouse wheel on the key: ± 0.5 dB, 1-second press: 0 dB), SPEED (FAST / MID / SLOW), RBW (WIDE / MID / NAR), VBW (NARROW / WIDE), MARKER — another 1-second press goes back to <MENU1>; 1-second press on EXPD/SET: SCOPE SET (3 pages in radio order: Scope during Tx, Max Hold, CENTER Type Display, Marker Position, Averaging, Waveform Type, colours (same R / G / B window), Waterfall Display / Speed / Size / Peak Color Level / Marker Auto-hide, Dual Scope Type, Dual Scope Auto Select, Fixed Edges of the current range); a 1-second press on the main-screen meter scale (bars or needles) shows the MULTI-FUNCTION METER alone, and M.SCOPE (or another 1-second press) goes back to the previous screen; EXIT does not change that screen: leaving MENU, SET, ANTENNA or FUNCTION brings you back to the screen chosen with M.SCOPE, as on the radio), SWR (read in TX), ANTENNA (under the shortened scope: ANTENNA MEMORY = antenna 1 – 4 for each of the 12 frequency ranges, the current range in light blue, click = next antenna; [ANT] Switch Manual / Auto; TYPE ANT1 – ANT4, RX-ANT and external tuner (EXT) read-only; Temporary Memory; ANT, RX-ANT, ANT MR, ANT MW, TEMP-M, [ANT] SW, TYPE keys; ANTENNA MEMORY, TEMP-M and [ANT] SW settings are admin-only; leave with ↩ right of the title or EXIT); FUNCTION key: FUNCTION panel under the (shortened) scope, as on the radio — APF (CW only), NOTCH, NB, NR, TRACKING / VOX (BK-IN in CW), TBW, MONI, DPD; click: next value or ON / OFF, blue frame = on; FUNCTION or EXIT closes it.

SPAN / EDGE, HOLD and CENT/FIX set the active VFO's scope on the radio, as on the IC-7300: SPAN (in CENTER) sets the width, EDGE (in FIX) picks edges 1 to 4, HOLD freezes the scope, CENT/FIX switches CENTER / FIX (long press: SCROLL-C / SCROLL-F). MAIN/SUB changes the active VFO, DUAL switches between one and two scopes. With the MULTI column open, EXPD/SET disappears and the column's ↩ key closes it. The small right-hand screen shows the selected receiver's filter (width, TWIN PBT, NOTCH). MAIN / SUB keys above the main dial: receiver of the main dial; NB, NR, NOTCH (OFF → AN → MN), APF/TPF, the TWIN PBT knob (push: CLR) and the FIL key of the small screen act on the selected receiver, as on the radio. MAIN AF ◎ RF/SQL and SUB AF ◎ RF/SQL: volume and gain of each receiver. CHANGE swaps MAIN and SUB (1 s press: MAIN = SUB), DUAL-W dual receive, SPLIT transmits on SUB, XFC listens on the transmit frequency while held. RIT / ΔTX / CLEAR and the RIT/ΔTX knob for the offset. Below the screen: MENU = mode table, FUNCTION = Icom FUNCTION screen (P.AMP, ATT, AGC, NOTCH, NB, NR, DIGI-SEL, IP+, APF, VOX/BK-IN, COMP, TBW, MONI, TRACKING, DUAL-W), MULTI knob pushed = MULTI column on the right of the screen (RF POWER, MIC GAIN, COMP, DIGI-SEL, MONITOR; in CW KEY SPEED and CW PITCH instead of MIC GAIN and COMP): click a box then turn the MULTI knob (the value changes), ↩ to leave, M.SCOPE = multi-function screen (scope, oscilloscope, AF-FFT), QUICK = band table, EXIT. Small screen: selected receiver, filter width, filter drawing, FIL, APF, AN / MN.

• Band keys act on the active receiver (MAIN or SUB); white LED under = MAIN band, blue above = SUB band. MAIN / SUB, MAIN/SUB choose the receiver (the chosen key is lit as on the TRX: MAIN white with black text, SUB blue). RX SUB = dual receive; TX MAIN / SUB = transmit VFO. SPLIT on: transmission moves to the VFO that is not selected (MAIN selected → TX SUB; SUB selected → TX MAIN); SPLIT off: it returns to the selected VFO; MAIN⇆SUB swaps (hold 1 s: copy MAIN → SUB).
• MODE: next mode; hold at least 1 s: the table of all modes, click the one you want. SSB, CW (switching to CW from another mode turns BK-IN on; BK-IN can then be turned off or on again without changing mode), BK-IN, SPLIT, CLAR RX / TX, big CLAR (hold: offset to zero), LOCK, FAST (1 kHz per notch) / FINE (1 Hz per notch).
• NB DNR DNF NOTCH CONT APF: top row SUB, bottom row MAIN; NB / DNR: short click on / off, hold at least 1 s: « NB LEVEL » / « DNR LEVEL » box on the screen (− / + or wheel). Knobs: wheel or drag; dual knobs: centre = inner knob, edge = ring; SHIFT ◎ WIDTH: WIDTH 300–4000 Hz in SSB with the default width in the middle, SHIFT −1200 to +1200 Hz; small orange LEDs above when not at default; hold the centre at least 1 s: SHIFT 0 and default WIDTH; the screen filter follows the width.
• MULTI: clarifier offset when CLAR is on, otherwise the function shown in the last box of the screen (« MULTI RF POWER » at first), chosen in FUNC. FUNC opens the function menu in the screen, used with the mouse: click a box (red frame), then click − (left of the box) or + (right), wheel over it or turn MULTI (RF POWER, MONI LEVEL, DNR LEVEL, NB LEVEL, VOX GAIN, VOX DELAY, ANTI VOX, R.FIL, MIC EQ, STEP DIAL, and in FM RPT, ENC/DEC, TONE FREQ of the selected VFO, read from the TRX; SPEED, PEAK, MARKER, COLOR, LEVEL for the page waterfall and, with control, the TRX scope (MAIN or SUB, selected side; changes made at the club are followed by the page); SPAN too (1 kHz to 1 MHz on the TRX, the page showing received audio, 5 kHz max). RADIO / CW / OPERATION / DISPLAY SETTING open the TRX menus as on its screen (sub-menus on the left, settings with their value read from the TRX on the right; click a setting then − / +, wheel or MULTI, with control: written to the TRX and read back; greyed settings are read-only). EXTENSION SETTING: at the club only. Grey boxes: not available remotely (memories, SCAN, DECODE, REC/PLAY). As on the TRX, some boxes grey out depending on the selected VFO's mode: RPT, ENC/DEC and TONE FREQ outside FM; MIC EQ in CW, DATA, RTTY and PSK; DECODE in FM.
• Below the panel, on one line: the big PTT button (hold, or the space bar) and 👁 Suivre l'opérateur; below, the MODES row. Remote phone settings (microphone, audio input / output, equalisers, MONITORING, operator profile) are in the TRX SSB page, as from the dashboard, so the whole front panel fits on the screen (its width follows the window height). MOX: latched transmit (click: TX, next click: RX). MONI: hear your own modulation (« MONITORING », headphones; microphone on first). Band map: full-height column on the right.
• TUNE: tuner on / off; hold at least 1 s: tune (after confirmation). VOX (can only be switched off), PROC.
• PHONES jack: listen. 🎧 Stéréo MAIN | SUB: switches dual receive on, then MAIN in the left ear and SUB in the right ear (handy in SPLIT with a headset).
• Screen: meters (S MAIN / SUB; TX: PO, SWR) with each receiver's filter (in CW, below the filter, the tuning indicator « − … + » as on the TRX: red mark in the middle = the pitch, small grey line = the strongest signal within ± 200 Hz; line in the middle (white) = tuned, it stays in the middle when transmitting; NOTCH on: a dip in the passband at its frequency; CONT on: a small shallow blue « V » at the top of the filter at the CONTOUR frequency, following the CONT knob (the deep dip is the NOTCH), as on the TRX), frequencies (click to type), ANT / ATT / IPO / R.FIL / AGC (click: next value), and instead of the TRX scope (not sent over CAT) the spectrum and waterfall of the received audio, MAIN | SUB side by side in dual receive (FAST: also switches the FTDX101's FAST key on the selected side, MAIN or SUB; LED read from the TRX); each part runs from 0 to the top of its filter passband (within the SPAN) so it fills its whole width; in the small filters next to the S-meters the spectrum is drawn on the filter scale. The MULTI box at the bottom of the screen shows, as on the TRX, the selected VFO's scope with an OSCILLOSCOPE (10 ms/div) and an AF-FFT (0–4 kHz with waterfall) below; click again to go back. Bottom row: SPAN (2 to 6 kHz), MONO (as on the TRX: a single VFO on screen, the selected one — meter left, large filter right, frequency, full-width boxes, one scope; MONO shown in blue; click again: MAIN and SUB), EXPAND (as on the TRX: meters reduced to their top part, flattened filters, frequencies moved up and larger scope; EXPAND shown in blue; click again: normal display), MULTI (FUNC menu), HOLD (freeze). Top right: 👥 and the number of connected members; click: their callsigns (connection IP address for administrators), who has control, and messages between members (🔔 beep and red dot when a message arrives), as in the dashboard; next to Take / Release control, your callsign (and the controller's if someone else). 👁 Suivre (follow the operator, for remote training; below the front panel, right of Profil de …, greyed out for the one in control): your front panel shows the same screen as the operator (DISP, MONO, EXPAND, MULTI, 3DSS, FUNC menu); it turns on by itself when another member has control; one of those keys stops it, a click on 👁 Suivre restarts it. In the 📟 Digital page, the button of the same name follows the digital-mode tab. Above SSB CONFIGURATION, the MODES line (FT8/FT4/FT2, SSB, RTTY, WSPR, JT65, JTTY, CW, SSTV): SSB opens TRX SSB, CW opens TRX CW, the others open TRX DIGI (/ftdx101/digi.html) on that mode, or switch it there if already open. Right after: DX Cluster, as in the dashboard: opens dx.op0p.be or cluster.op0p.be in its own window linked to the TRX (click a spot: the selected VFO goes there, with control); « open automatically at each connection » box (opens on the first click in the page). The server's cluster spots always reach the band maps.
• Front-panel digital modes: the MODES row opens TRX DIGI (digital modes page, /ftdx101/digi.html) on that mode (SSB: TRX SSB; CW: TRX CW); the mode shown there is lit in light blue. On that page: LOGBOOKS opens the station log in its own window (entry, list, sync to LoTW / eQSL / Club Log / QRZ, ADIF or Cabrillo export; all QSOs go to the same station log), SYNCHRO (FT8 / FT4 / FT2, WSPR, JT65 only), Follow the operator (same as the front-panel FOLLOW button), and on the tab line, right after SYNCHRO, the TX call choice (fluo yellow). Announcements are fluo yellow and blink for 1 s. Hover a call to see its DXCC country, distance and bearing.
• FT8 / FT4 / FT2 on MAIN and SUB: with DUAL RX on, both receivers are decoded at once: two waterfalls side by side (VFO-A · MAIN left, VFO-B · SUB right) with each VFO's frequency large — on red with « TX » for the transmitting VFO — and its mode; four columns (band activity and RX frequency for each VFO) separated by a grey line, each with its own scrollbar. Each waterfall has its RX / TX marks (the TX flag is blue on the VFO that doesn't transmit), mouse-wheel zoom (down to 300 Hz; the same for both waterfalls, so both VFOs show the same width), its own settings and a height grip. Double-click a message (or click its call) in a VFO-B column: the reply goes out on SUB; in a VFO-A column, on MAIN. The TX VFO-A / VFO-B buttons show and change it and follow the TX VFO chosen on the TRX. Two band maps: VFO-A on the left, VFO-B on the right, each with its own filters and scrollbar. Same in the TRX DIGI page opened from the dashboard (FTDX101 with DUAL RX): both VFOs may be on different bands, each band map shows its own VFO's band. DUAL RX off, or a single-receiver rig (FTDX10, IC-7300…): one waterfall, two columns and one band map.
• JT65, WSPR, JTTY on MAIN and SUB: same layout as FT8 in DUAL RX — two waterfalls side by side, VFO-A decodes on the left and VFO-B decodes on the right (WSPR: stations heard by each receiver; JTTY: activity and RX frequency of each VFO; double-click a VFO-B message to transmit on VFO-B), two band maps.
• CW on MAIN and SUB: FTDX101 in DUAL RX — two separate CW receivers: two waterfalls and two receive panes, each with its own filter, squelch, level, tone and speed. Click a waterfall to lock onto the nearest signal, hold the left button to drag the marker. Double-click a received callsign: it becomes the DX station and transmission moves to the VFO it was heard on.
• CW zoom and TRX filter: mouse wheel on a CW waterfall zooms around the pointer (down to 200 Hz wide). The two light-blue bars show that VFO's TRX filter (WIDTH or NAR) centred on the CW pitch, following the TRX. With control: drag a bar, or Ctrl + wheel on the waterfall, to set the TRX bandwidth.
• RX MAIN / RX SUB (FTDX101 front panel): like the TRX RX keys — RX MAIN mutes or restores the MAIN receiver (e.g. to listen to SUB only), RX SUB switches DUAL RX on or off. Green LED = receiver on.
• RTTY on MAIN and SUB: two decoders, one per receiver, each with its waterfall and band map. Each decoder header shows the VFO frequency large, as on the TRX (red « TX » for the transmitting decoder) and the tracked signal frequency small. Decoders start on 1500 Hz. The frequency scale above each waterfall tunes the VFO (wheel: 10 Hz per notch, 50 Hz when spinning fast; or drag), across the whole band, while the decoder marks stay put; set the marks inside the waterfall (click / drag; wheel there = zoom), as in FLDIGI and MixW. Height grip under the decoding windows. Default squelch 9 dB (about −6 dB SNR in 3 kHz).
• RTTY macros and contests: 12 personal macros (F1–F12, saved on the server under your call; right-click or ✎ to edit). F11 « TX » sends the typed text, F12 « RX » returns to receive. The editor lists the macro tags (FLDIGI standard fields) by group with help on hover and a preview. Contests: contest list taken from N1MM Logger+, editable exchange (<EXCH>), name, CQ / ITU zones, serial number (advanced by the TU macro once per station; −1 / +1 / ↺ 001), and a second row of 12 contest macros on F1–F12 when a contest is chosen (by default F10 TX = send the typed text, F11 RX = back to receive, F12 Log = QSO form); to its right, RÈGLEMENT ↗ (rules) opens the contest's official rules (CQ WW RTTY, CQ WPX RTTY, ARRL RTTY Roundup, WAEDC RTTY), otherwise a web search for the rules, in a new tab. The QSO form keeps sent / received exchange and contest for Cabrillo.
• SYNC (LED on): SUB takes the MAIN frequency and the main dial then tunes both receivers together; click again: off. KEYER: CW electronic keyer. Clicking the MIC/SPEED ◎ PROC knob without turning: KEYER in CW, PROC in SSB (LED on; click again: off).
• Finer spectrum (2048-point analysis, each column keeps the strongest peak).
• Band map: right-hand column, full height. Its ⧉ button moves it into its own window (another screen, any size); ⧉ Ramener or closing the window brings it back. Reopened on the next page load if Chrome allows pop-ups for the site.
• Digital modes: the ⧉ button at the end of the tabs opens them in their own window (with their band map, same connection); ⧉ Ramener sous la face avant brings them back.
• CONT/APF ring around the NOTCH knob: CONTOUR frequency (10–3200 Hz); in CW with APF on: APF frequency (−250 to +250 Hz). Hold the NOTCH centre at least 1 s: NOTCH 1500 Hz, CONTOUR 1000 Hz, NOTCH / CONT / APF off. LEDs above SYNC, SPLIT, CLAR RX / TX, FAST, LOCK light orange when on. PROC only in SSB / AM on the transmit VFO.
• PROC / KEYER: bright orange LED above the MIC/SPEED knob while the processor (SSB) or keyer (CW) is on; click again: off.
• DISP, as on the transceiver, one click after another: MAIN waterfall → SUB above MAIN → MAIN | SUB side by side → enlarged filters (each receiver's width and shift with its audio spectrum) → back. To see SUB: 🎧 Stéréo MAIN | SUB.
• VC TUNE: the small key switches the preselector of the active receiver on / off (orange LED, off when stopped). The large VC TUNE key, independent, makes the outer ring of the main dial tune the preselector (LED to its left); click again: the ring tunes the frequency of the other receiver than the selected one (SUB selected → VFO A, MAIN selected → VFO B). As on the TRX, a red « − … + » bar above the filter shows the preselector position.
• S.MENU: the SCOPE MENU as on the transceiver, over the top of the waterfall: SPEED, PEAK (peak hold OFF / LV1 … LV3), MARKER (filter passband and centre marker), COLOR, LEVEL (click left −, right +, or wheel). Closes by itself 3 s after the last action.
• No effect remotely (a message explains): ON/OFF, ZIN/SPOT, QMB, C.S, memories.

12. Digital modes

The centre tabs: Modes, FT8 · FT4 · FT2, RTTY, WSPR, JT65, JTTY, CW, SSTV, then Logbooks, the Log QSO button and Synchro. With control, clicking the tab of a digital mode (FT8 · FT4 · FT2, RTTY, WSPR, JT65, JTTY, SSTV) puts the TRX in DATA-U (USB-D on the IC-7300) on the VFO being received, even below 10 MHz; the CW tab puts it in CW (CW-L below 10 MHz, CW-U above; CW-R / CW on the IC-7300), unless it already is. On the right of the FT8 · FT4 · FT2, RTTY, WSPR, JT65, JTTY and CW tabs, the band map shows the DX cluster spots (see 12.3, « Band map »). You have no software to install (no WSJT-X, FLDIGI…): everything happens in the page.

• Decoding runs on the server, on the server's (synchronised) clock: the time on your PC and on the club PC does not matter.
• The TRX audio is only sent while someone is listening or watching a digital-mode tab: decodes start a few seconds after the tab is opened.
• Frequency list (at the top of each tab): choosing a line sends the TRX to that frequency, in DATA-U (in CW for the CW tab). You need control. The ↺ button next to it brings the TRX back to the chosen frequency if someone has turned the VFO in the meantime.
• Waterfall: each tab shows the scrolling spectrum from 0 to 3000 Hz. A signal is a coloured trace; its horizontal position is its audio frequency.
• Status line (on the right of the tab bar): reports problems (station offline, audio not enabled, TRX not in DATA-U…) or the decoder state.
• Transmitting in FT8 · FT4 · FT2, RTTY, JTTY, CW and SSTV, under the TX call chosen in the Correspondant line (ON5VL or your callsign). You need control and transmit permission. WSPR and JT65 are receive-only for now soon.

Waterfall settings (above the scale, shared by all tabs and remembered in your browser)

12.1 FT8 · FT4 · FT2

FT8 is a digital mode designed for very weak signals: each station sends a short message for 15 seconds (a period), then listens during the next period. A complete QSO takes about a minute and a half. FT4 is twice as fast (7.5 s), FT2 faster still (3.75 s).

The bar at the top of the tab

The waterfall: left click = receive frequency (green « RX 1500 » flag and green line), right click = transmit frequency (red flag and red line). Button held down (left for receive, right for transmit): the line follows the mouse continuously, as in RTTY and CW (FT8 · FT4 · FT2, WSPR, JT65, JTTY); members following the operator see it move. For transmitting, choose a clear spot in the waterfall. A white line marks the start of each period, with the UTC time and the band. When the rig's NOTCH is on, an orange dotted line marked "NOTCH 1500" shows the cut frequency on the waterfall (FT8 / FT4 / FT2, JT65, JTTY; one per VFO with dual receive): avoid putting your RX marker there.

The spectrum, below the waterfall (like WSJT-X's "Spectrum"): green curve of the level of each audio frequency, averaged over the last lines (same Gain, Zero and Flat settings as the waterfall); a signal stands out as a peak. At the top left of the spectrum, X1 / X2 / X4 set its speed: X1 = average over about 6 s (calm curve, steady signals stand out), X2 = about 2 s, X4 = almost instant (kept in this browser). They only set the curve; the waterfall's scrolling speed is chosen in its "Vitesse" list. The handle between the waterfall and the spectrum sets the waterfall height; the handle at the very bottom sets the spectrum height (double-click: original size). With dual receive, VFO-B has its own spectrum, of the same height.

The two message lists

• Activité de bande (band activity, on the left): all decoded messages. CQ calls are in green, messages addressed to your TX call (ON5VL, OR0L or yours) in red, your own transmissions in yellow. Effacer (clear) empties the list.
• Fréquence RX (RX frequency, on the right): only the messages close to your receive frequency, i.e. your QSO in progress. Each list has its own Effacer (clear) button: the band activity one clears the history of both lists, the RX frequency one clears only that list.
• A line separates each period; messages are in chronological order.
• Width of the two lists: drag the vertical line between them (double-click: half and half).

• Stations already worked: messages from a station already in the log under the current TX call, on the same band and in the same mode, are shown green and struck through ("worked before"). With another TX call, only QSOs made under that callsign count.

Messages Tx1 to Tx7 (below the lists, as in WSJT-X)

• Clicking a Tx message sends it every period (one in two) until an answer comes, like WSJT-X's "Enable Tx". You need control, the transmit VFO in DATA-U and power within your limit.
• Answering a station: click its callsign (dotted underline) or double-click its message. It becomes the correspondent (callsign, locator, report) and, with control, the right message goes out in the next period, opposite to theirs. A click elsewhere on the line only sets the receive frequency.
• The sequence advances by itself from the answer: their locator → Tx2; their report → Tx3; R+report → Tx4 (RR73); RRR or RR73 → Tx5 (73). After RR73 or 73: end of QSO, transmission stopped, back to Tx6, and the Enregistrer le QSO form opens already filled in.
• When the answer goes out: in FT8, a transmission must start at the beginning of a period (at most 2.3 s late, otherwise it is no longer decoded; FT4: 0.8 s). Decodes arrive around 12.7 s: a click before the end of the correspondent's period (or in the first 2 seconds of the next one) sends the answer at once. Transmission always stops at the end of the period. A message at the bottom of the screen says when your answer goes out.
• Period bar (below the lists): green while receiving, red while transmitting; it fills up during the period.
• Automatic stops: ■ Arrêter or Space; the correspondent answers someone else; the same message for 6 minutes without an answer; control lost.
• In SPLIT, the message goes out on the other VFO, like the PTT.

Hunting (DXpedition…): in the FT bar, the DX field takes one or more calls or prefixes separated by spaces (e.g. 3Y0K VP8 FT8W); after Enter, the band activity only shows their messages, for both VFOs (gold mark on the left, message in yellow; yellow frame around the field). Clear the field (QSO done): no call chosen any more, all traffic comes back at once. The RX frequency columns are never filtered (your QSO).

The QSO window (below the Tx1 to Tx7 messages). It is hidden by default, leaving all the room to the traffic windows. The yellow DÉTAILS QSO button (right of ARRÊTER, on the macro line) shows it; click again to hide it. It also appears by itself as soon as you click a call (decode lists or BAND MAP) or a station is taken by the sequence (answer to your CQ), and hides 2 seconds after the QSO is saved: automatic log or ENREGISTRER LE QSO, according to Paramètres Logbook. In the TRX DIGI page opened from the dashboard, it is the logbook form (like "Log QSO"): callsign, UTC date and time (QSO start), frequency, mode, RST sent / received (the FT reports), TX call, QO-100, name, QTH, locator (⇩ QRZ), power, remark, the correspondent's IOTA / WWFF / POTA / BOTA / LLOTA / SOTA references — filled by itself with the chosen correspondent (double-click) and the sequence's reports. Buttons: Enregistrer le QSO, then Modifier le QSO (reopens the last QSO saved from here to correct it) and Supprimer le QSO (removes it from the logbook; online logs are not changed) — these two buttons are also in the TRX SSB page form. Elsewhere (front panel pages, modes brought back into the dashboard): short card of the current correspondent — callsign and locator (editable by hand, like WSJT-X's "DX Call / DX Grid"), country, distance and azimuth, report sent and received, start time (when the correspondent was chosen) and transmit step ("Tx3 à la prochaine période", "● Tx3 en émission"). LOG QSO opens the logbook form at any time (interrupted QSO, manual logging); EFFACER clears the correspondent.

HOUND: working a DXpedition in FOX or SuperFox mode

Big FT8 DXpeditions run FOX mode: the DXpedition (the FOX) works several stations at once, and the callers (the HOUNDS) follow strict rules that the Remote Station applies by itself, as WSJT-X does.

• Activité (top bar, FT8): HOUND · FOX for classic FOX (several FT8 signals below 1000 Hz), HOUND · SuperFox for SuperFox (one wide signal of about 1.5 kHz around 750 Hz, addressing up to 9 stations at once). The DXpedition's announcement says which one and its frequency (often not the usual FT8 frequency).
• Calling: double-click the FOX's CQ → Tx1 ("FOX ON5VL JO20") goes out in the 2nd period (the FOX transmits in the 1st). Only Tx1, Tx3 and Tx5 (73, by hand: not needed, the FOX's RR73 already ends the QSO) can be used; no CQ. The period is locked to the 2nd ("15/30").
• Classic FOX: call above 1000 Hz (if your TX marker is lower, a random frequency between 1000 and 2900 Hz is used). When the FOX gives you a report, Tx3 ("FOX ON5VL R-10") goes out by itself on the frequency where the FOX called you, then 300 Hz away if it must be repeated. Its messages can address two stations: "K1ABC RR73; ON5VL <KH7Z> -12".
• SuperFox: the RX marker moves by itself to the low edge of the SuperFox signal (750 Hz, then wherever the signal is decoded); the decoder searches 450 to 1050 Hz, then around its last position. The 1st period is decoded by WSJT-X's SuperFox decoder: each part of the message is shown on its own line marked SF (CQ, reports, RR73), and the DXpedition's password marked OTP ("$VERIFY$ …": it proves the signal really comes from the DXpedition; it can be checked on 9dx.cc). The whole QSO stays on your calling frequency (you may call anywhere, below 1000 Hz too).
• End of QSO: the FOX's RR73 ends the QSO (no 73 is sent); the "QSO terminé" form opens (or the QSO is logged by itself, according to "Log"). With no RR73 within 11 periods after its report, transmitting stops: call it again with Tx1.
• Go back to Normale after the DXpedition, otherwise other stations cannot be worked normally (CQ, 73…).

12.2 JT65

Same window as FT8, but with one-minute periods; the TRX goes to the JT65 frequency of its band. Decodes arrive around the 52^nd second. Receive only.

12.3 RTTY

Contest serial numbers kept by the server (since version 0.41.1, RTTY, CW and SSB pages): one series per contest and TX call for the whole station; two operators (two browsers) never get the same number. Each position keeps its number « in hand » until the QSO is logged; an abandoned QSO leaves no gap (the number goes to the next station). Changing the number by hand (± or N° field) is refused if it is already given or in hand elsewhere (orange message). Back to 1 (new contest edition) applies to all positions: administrator or the operator in control. The numbers of one edition are those of the last 4 days: the same contest next year starts again at 1.

High-sensitivity decoder (since version 0.40.6), based on the ideas of 2Tone: each decoder follows the signal by itself up to ±40 Hz (AFC: a click slightly off is enough), tries several bit sampling instants and two Mark / Space decision methods for each character (one of them resists selective fading), and keeps the cleanest frame. The squelch stays open a little lower for 2.5 s after a sure character, so the letters of a fading signal are not lost. Measured on the test bench (white noise, SNR in 2.5 kHz): at −5 dB, 1 % errors instead of 7 %; at −7 dB, 10 % instead of 29 %; 20 Hz off at −5 dB, 4 % instead of 45 %; and fewer random letters on noise.

TRX RTTY page (separate window, opened by the RTTY tab of the dashboard): header like the SSB and FT8 pages — TX CALL, TRX frequency and mode, 👥 connected members, control button and 👁 SUIVRE L’OPÉRATEUR — then, at the top, both dashboard VFO screens copied (S-meter, filter, dial, AF spectrum, badges; click and wheel as on the dashboard) with SPLIT, A ⇄ B, A → B, DUAL RX and 🎧 STÉRÉO; on that line, left, the VFO A RTTY frequency (the TRX goes there, in DATA-U), ↺, Bande (3 or 4 kHz) and Zoom; right, the same for VFO B (Bande and Zoom shared by both waterfalls); the waterfalls and decoders below.

RTTY is radio "teletype": you type text that scrolls on the other station's screen. Widely used in contests. The tab has two independent decoders: A (VFO-A, left) and B (VFO-B, right), each with its own received text and settings. The FTX-1, FTDX10 and IC-7300 send a single audio stream to the PC (the FTDX101 in single receive; in dual receive it sends both receivers in stereo: one waterfall per decoder, A = MAIN, B = SUB), so there is one waterfall, full width, carrying the markers of both decoders. You can follow two stations on the same band at once (contest, a DX and its pile-up). A transceiver that sends its two receivers separately (FTDX101D / MP) will get one waterfall per decoder, side by side.

Above the waterfall, the help line (« clic gauche : décodeur A… ») is shown for 3 seconds when you open the tab, then disappears to leave more room for the receive windows; it stays as a tooltip on the waterfall. The status line only appears when something is wrong (no audio, TRX not in DATA-U…).

1. Layout: at the top, both VFOs as on the dashboard (frequency, mode, S-meter, SPLIT, DUAL RX, STÉRÉO), then two columns: on the left VFO-A (its waterfall, then its traffic window), then the QSO line, the macros and the contest; on the right VFO-B (its waterfall and window), then LOG RTTY. Only one VFO in use (neither SPLIT nor DUAL RX): no VFO-B column, LOG RTTY takes the whole right column — except with the the decoder list SINGLE / DUAL / QUAD list (right of the DUAL RX button of the top VFOs; purple in DUAL or QUAD): in DUAL: two pairs of bars on the same waterfall, as in FLDIGI: A1 (left click, yellow and blue bars) and A2 (right click, or right button held to drag its purple and green bars), two signals decoded at once; the VFO-A · A2 window shows in the right column, above the log (its ✕ MASQUER (hide) button, or SINGLE in the list, hides it: the log takes the whole column again). in QUAD: 4 decoders on the same waterfall — A1 (left click), A2 (right click), A3 (Ctrl + left click, orange / cyan bars) and A4 (Ctrl + right click, pink / light green bars); or choose the decoder in BARRES A1 A2 A3 A4, then left click (handy on a tablet; for that placement only: then left click is A1 again). Each traffic window is then split in two, side by side: A1 | A3 on the left, A2 | A4 on the right (the input line stays below, full width); A3 and A4 use the same shift and speed as A1; no Silencieux (squelch) setting on the RTTY page (fixed 9 dB threshold, a good compromise between weak signals and random characters on noise); each of the 4 has its RX ici / ▶ TX ici (A3 and A4: in their title): a click chooses that decoder for transmit (its window gets a red frame; a click in A3's / A4's window does the same), then F11 TX, a macro, or a 2nd click on ▶ TX ici; the column's input line holds the text; (same VFO; you can transmit on A2's frequency as on A1, handy in contests); VFO-B's windows come back as soon as SPLIT or DUAL RX is on.
2. TRX mode: when opening the RTTY page (and when coming back to it), if you have control, the TRX switches by itself to « data » mode: DATA-U (Yaesu), USB-D (Icom), USB+PKT / PKT-U (Kenwood), otherwise USB — on the listened VFO, and also on VFO-B with SPLIT or DUAL RX; the mode is sent again if the TRX recalls the band's stored mode.
3. Receive: left click on a signal for decoder A, right click for decoder B (button held: the bars follow the mouse continuously, to place them exactly on the traces). The two markers should sit on the two traces of the signal.
4. One window per VFO: received and transmitted text follow each other in it, in different colours — red = transmitted text (grey while waiting, red letter by letter as it goes out), green = the other station's lines (its call, or yours / the station's: someone calling you), white = other traffic. Effacer (top right) clears the window. At the bottom, the input line for the text to send.
5. Choose the transmit VFO: a click in its window, typing in its input line, or RX ici → ▶ TX ici; red frame = transmit VFO, green frame = receive only. Your reply goes out on the frequency of the station followed by this decoder (and on VFO B if SPLIT is on).
6. The other station: a click on its callsign in a traffic window puts it in CALL (QSO line, above the macros); macros use it (<CALL>) and its lines turn green.
7. QSO line (in a contest or not): CALL, sent RST, Envoyé (sent exchange, serial… — contest), received RST, Reçu (received exchange — contest) or Nom and QTH (outside contests); LOG ↵ (or Enter in a box of the line): the QSO goes straight into the general logbook (start time = when the call was chosen, signal frequency, contest and exchanges; name, QTH and locator completed from QRZ.com when possible), the line clears and the serial number moves on; EFFACER: clear the line; ☐ Spot cluster: the QSO is also spotted on the DX cluster under your operator callsign. The full form (locator, remark…) stays on the Log macro (<LOG>).
8. Transmit: text typed in the input line, then the F11 TX macro (or Ctrl+Enter); F12 RX (or Esc) stops transmitting. The text goes out with the settings of the transmit VFO's decoder, then the transceiver returns to receive. 600 characters at most; transmit audio frequency between 300 and 2800 Hz.
9. Macros F1 to F12 (keyboard keys or click), on two aligned rows (F1–F6, then F7–F12), white text: transmit at once; Shift+click adds the macro to the text without transmitting (section 13). Without a contest: the usual macros (F11 TX, F12 RX) and just the contest list; contest chosen: only the contest macros (by default F10 TX, F11 RX, F12 Log), with RÈGLEMENT ↗ (rules) to their right (official contest rules, otherwise a web search).
10. Contest: the list (« — pas de contest — » first, then alphabetical); exchange, CQ / ITU zones, serial number (−1, +1, ↺ 001) only appear in a contest; Prénom (first name — yours, <MYNAME> tag) only for a contest whose exchange needs it (NAQP, NA Sprint, TARA…).
11. LOG RTTY (right column, under VFO-B and as wide; shrinking VFO-B's windows makes the log taller; narrow screen: below the macros): the RTTY QSOs of the general logbook, newest at the top, updated by itself on every logged QSO (here or in another page); the last 300 are shown, all stay in the Logbooks tab. Same style as the SSB page logs, white frame. Columns: date, UTC, call, band, MHz, reports, name / QTH / locator (outside contests) or TX # / RX # (contest), DXCC (prefix), TX call, OP, Contest (empty outside contests). Without a contest: RTTY QSOs outside contests; contest chosen: only that contest's QSOs. A click on the LOG RTTY ⤢ title enlarges it in the middle of the page (click again or Esc: back).
12. Contest points: Pts column of LOG RTTY and total (without multipliers) in its title, for contests whose rules are supported — CQ WW RTTY (same country 1, same continent 2, other continent 3), CQ WPX RTTY (1 / 2 / 3, doubled on 40 and 80 m), ARRL RTTY Roundup (1 per QSO); dupe (same call, same band): 0. For other contests, no Pts column (rules: RÈGLEMENT button).
13. Export (EXPORTER ▾, right of the log title, as in the logbook): Mes QSO RTTY (.adi) = your QSOs under the current TX call (outside contests, or those of the chosen contest); ADIF (.adi)… = with filters: TX call, operator (your QSOs; an administrator can choose all operators or one operator), RTTY QSOs outside contests / all / of one contest, from / to dates; Cabrillo (.log)… = an RTTY contest log for the organisers (TX call, operator, dates, category, power, assistance — check the rules). A member only exports their own QSOs.
14. Column width (LOG RTTY, SSB page logs): drag the right edge of a column title to widen or narrow it (text too long cut with « … »); double-click that edge: original widths. Kept in this browser.
15. Heights: each VFO has its handle under its waterfall (waterfall height), its handle under its spectrum (green curve under the waterfall, same Gain / Zero / Flat settings) and its handle under its traffic window (70 px minimum); all are independent (VFO-A's do not move VFO-B); double-click: original size. The VFO area takes the height of the taller column.
16. Waterfalls (dual receive): RX ici / ▶ TX ici is right of « Vitesse » (speed) on each VFO's waterfall settings line. No X1 / X2 / X4 or ⌖ Centrer buttons on the RTTY page.

In practice: an RTTY contest QSO, almost without leaving the keyboard

1. Take control, RTTY tab, TRX in DATA-U (↺ button of the frequency list).
2. Find a station: click a green callsign on the band map. The TRX tunes to it, the transmit decoder decodes it and its callsign goes into Correspondant. Or: left click on a trace in the waterfall (decoder A), right click (decoder B).
3. Choose the transmit window: one click in the VFO-A or VFO-B window (« ▶ TX ici »). A click on a received callsign puts it in CALL.
4. Reply: F2 key (or the reply macro), then the report macro. For custom text: type it in the input line of the VFO's window, then F11 TX (or Ctrl+Enter). Esc stops the current transmission.
5. Log the QSO: LOG ↵ on the QSO line (or Enter), or a macro containing <LOG> (full form). In contest, Sent exchange is filled in by itself: the exchange sent to this station by a macro, otherwise the one to give (fixed report, zone… or this QSO's serial number). When the QSO is logged, the serial number moves to the next one (once per station, not again if the TU macro already did it). Spot cluster box on the QSO line (and in the form): the logged QSO is also spotted on the DX cluster, under your operator call.
6. Call yourself (CQ): choose the transmit window, then F1. With two decoders you can call CQ on A while watching another station on B.
7. Station outside the waterfall and not spotted: click the band map at that frequency (the TRX goes there), or wheel / drag on the frequency scale above the waterfall (also Shift + drag, Shift + wheel in the waterfall).

Band map (DX cluster)

On the right of the FT8 · FT4 · FT2, RTTY, WSPR, JT65, JTTY and CW tabs (not SSTV: a single frequency), a vertical column shows the band as a ruler (on a large screen it goes up to the top, next to the VFO A and B displays, both narrowed by the same width): low frequencies at the top, high at the bottom (by default 7030–7120 kHz on 40 m, 14080–14150 kHz on 20 m, 3570–3600 kHz on 80 m…). Spots from the club's DX cluster (OP0P, including stations found by the Reverse Beacon Network) appear at their frequency. You see the whole RTTY part of the band at a glance, while the waterfall only shows 3 or 4 kHz.

Cluster settings (administrator, config.json, then restart the service): clusterHost (op0p.be by default; empty = no cluster), clusterPort (8000), clusterCall (login callsign with an SSID; empty = digiCall followed by -7, i.e. ON5VL-7) and clusterCmds (commands sent after logging in: set/skimmer for RBN spots).

12.4 WSPR

WSPR is used to study propagation: low-power beacons transmit their callsign, locator and power every 2 minutes. Choose the band in the list; about ten seconds after each even minute, the list grows: time, dB, DT, frequency, drift, callsign, locator, power and distance from the station. Receive only.

• WSPR beacons only use 200 Hz of the audio band, from 1400 to 1600 Hz (reminder at the top of the tab): the frequency in the list (e.g. 14.0956 MHz) is the VFO frequency in USB / DATA-U.
• The ↺ button brings VFO A back to the chosen WSPR frequency; Effacer (clear) empties the list; the number of stations heard shows in the title.
• The clock shows the server UTC time: each 2-minute period starts on even minutes.
• TRX WSPR page (separate window): at the top, the dashboard's two VFO displays, as on the RTTY page, with the line SPLIT, A ⇄ B, A → B, DUAL RX and 🎧 STÉRÉO. On that line, on the left the WSPR frequency of VFO A and its ↺, on the right that of VFO B and its ↺: VFO B goes there at once, in DATA-U (USB-D…). Each list follows its VFO's band when the band is changed on the TRX.
• Two bands at once (TRX with two receivers, FTDX101D / MP): put VFO A on one WSPR band (e.g. 20 m) and VFO B on another (e.g. 40 m), then DUAL RX ON. A second waterfall (VFO-B · SUB) and a second list VFO-B · Stations WSPR entendues (stations heard) appear on the right, with their own Effacer (clear) button, plus the VFO B band map. On a single-receiver TRX, only the VFO A band is decoded.

12.5 JTTY

• WSJT-X 3.3 mode for keyboard-to-keyboard and contests: no periods, each message appears frame by frame (1.9 s); ▌ = message still being received.
• As in FT8: left click = receive, right click = transmit, double-click = correspondent. Two lists: Activité JTTY (JTTY activity) and Fréquence RX (RX frequency).
• Macros F1 to F8: a click transmits at once, Shift+click adds them to the message.
• Émettre (or Enter): the message goes out at once on the TX frequency, then back to receive. 80 characters per message (longer: two messages in a row); TRX in DATA-U.

12.6 CW

• Click a signal in the waterfall: the decoder locks onto the nearest signal and learns its speed. Right click: exact tuning where you click. Left button held while dragging: the yellow decoder marker follows the mouse continuously (decoding follows during the move) and stays exactly where you release, like the RTTY bars.
• Double-click a received callsign = correspondent; Log QSO opens the logbook form.
• The decoder (since 0.23.1) works like the ear: it retunes by itself to the exact tone of the signal (up to ± 60 Hz from the marker with the 100 Hz filter), filters as narrowly as the speed allows (about 1 / dot), and runs three decoders in parallel (fast, medium, slow), keeping the one whose dots and dashes have the most consistent lengths. It copies much weaker signals than before; it needs a few letters to find the speed of a new station.
• CW transmission, by the TRX keyer (no audio is sent: the TRX makes the Morse itself, as with its memories):
  • Vitesse (speed, 5 to 60 wpm, 48 on the IC-7300): keyer speed, sent to the TRX with each transmission.
  • Macros F1 to F12 (key or click): red edge = immediate transmission (CQ, Appel, Report, R TU, 73, QRZ?, AGN?), as in RTTY; Shift+click adds it to the text without transmitting. <CALL> without a correspondent: nothing is sent.
  • Text: typed in the box (upper case), then Émettre (transmit) or Ctrl+Enter; the box empties when transmission starts. Characters sent: letters, digits, / ? . , = + - and spaces; <AR> becomes + and <BT> becomes =; anything else is ignored. 300 characters at most, and no longer than the maximum transmit time.
  • While transmitting, a big flashing red ■ ARRÊTER (Échap) (stop) button appears in the Émission title, above the macros (macro sent by mistake…); the Émettre button also becomes ■ Arrêter and the bottom line shows « ● En émission CW (callsign, speed, duration) ». A click or Esc stops at once.
  • Conditions: control, transmit permission, an allowed band and power, the TRX in CW (CW-L / CW-U, CW / CW-R on the IC-7300) and no SPLIT (the keyer transmits on the receive VFO).
  • FTX-1: DTR keying (recommended): if the « Port de manipulation CW (DTR) » is chosen on the Station page (section 18), the page keys the TRX itself through that port; otherwise it uses the keyer memory, described below.
  • What the Station page does: keyer speed, break-in on (the TRX transmits by itself during the Morse and returns to receive), text written to a keyer memory and played, in 50-character pieces (30 on the IC-7300). Note: memory 5 of the FTX-1 (menu CW MEMORY 5, set to TEXT by the dashboard) and memory 1 of the FTDX10 / FTDX101 are replaced by the transmitted text. Each step (memory written, playback accepted, transmission) shows under the bands; one click is enough: transmission is recognised from the TRX TX state or from the output power (Po); if nothing is seen after 1.6 s, the page repeats the playback once (break-in turned on again) and then lets it play. The actual delay shows under the bands ("on air 1.2 s after the request"). A macro clicked during a message replaces it at once (no need to wait for the end). The transmitted text appears in the CW receive area as in RTTY: red for letters already sent, grey for those still to go (struck through if transmission is stopped early). Preparation in advance: the macro under the mouse, the text being typed and, when idle, the first macro (F1, CQ) are already written to the TRX memory (without transmitting); the click then only starts playback, so transmission starts as fast as the TRX allows. TRX menu PC KEYING on OFF: on DTR or RTS the FTX-1 refuses to play its memories (KY05 refused). On the FTX-1 the memory method is slow (the TRX does not play a memory just written, and does not always report transmission): DTR keying (Station page) is recommended, transmission then starts in under half a second. Fast switching: speed, break-in and text already in memory are not sent again for the next message, so a repeated macro goes out at once (everything is sent again after a stop, an error or 20 minutes). A setting already in place that the FTX-1 refuses ("?") is only written to the log. On stop, playback is interrupted (FTX-1: KY00, break-in left as it is; FTDX10 / FTDX101: break-in turned off).
  • Safety: the same as any transmission (bands, power, SWR), stop if control is lost, if the link or the station drops, and maximum duration.
• CW key from home (paddles or straight key, since 0.37.174): the Clé → TRX line under the Transmit frame. The keyer runs in your browser with a local sidetone, so you hear your keying without delay; dots and dashes are sent time-stamped to the server and the Station page replays them at the same rhythm on the DTR line of the TRX's 2nd USB port. The TRX transmits about 0.2 to 0.3 s later (Internet): no QSK, the TRX's break-in returns to receive after each pause.
  • TRX CW page (blue 🎛 TRX CW button at the end of the key line): a full page in the spirit of the W1VE Keyer Suite, attached to the dashboard (same connection, same control): large speed display and sliders (speed, weight, pitch, volume), key type and connection, large on-screen paddles, large CLÉ → TRX button, F1 to F12 macros (right click or ✎: edit), other station, text to send (Enter), ■ ARRÊTER, CW reception, large RX / TX light, and at the bottom the link state (round trip in ms). The speed there applies to the key and to macros. While this page is open, the key of the dashboard CW tab is on standby (one key at a time). Refusals ("put the TRX in CW first"…) are shown there too.
  • CW contest (CONTEST line of the TRX CW page): list of CW contests (CQ WW, CQ WPX, ARRL DX, IARU HF, WAE, UBA DX, ON Contest, EU HF, OK/OM, RDXC, SP DX, HA DX, YO DX, LZ DX, King of Spain, Helvetia, PACC, WAG, All Asian, JIDX, CWops CWT, other) with the exchange of a Belgian station, editable (<CNTR> = serial number, <CQZ> CQ zone 14, <ITUZ> ITU zone 27; a first name required by the contest is typed directly in the exchange; "00" to fill in: age, licence year; UBA DX and ON Contest: section, LGE for the club); on the right, in green, what will be sent. N°: serial number, automatic +1 with the TU macro (<INCR>), only once per station (sending TU again does not skip a number); −1 / +1 to correct. Choosing a contest shows 12 contest macros (yellow): CQ TEST, Exchange, TU, My call, His call, Answer, AGN?, NR?, ?, QRZ?, R, Log (QSO form with the sent exchange and the contest); F1…F12 then go to the contest macros, the usual macros stay available by click. Same serial number as the RTTY contest.
  • Contest log (N1MM style, under the CONTEST line): entry line Call · RST · Sent · RST · Received, LOG ↵ and EFFACER (wipe, Alt+W). Space jumps from the call to the received exchange. Enter does it all (N1MM ESM): in RUN (you call CQ): empty line → CQ (F1), call typed → call + exchange (F2), received exchange typed → QSO logged + TU (F3); in S&P (you answer): call typed → your call (F4), received exchange typed → TU + exchange (F6) and QSO logged. Sent is filled in by itself, as in the TRX SSB page: the contest's fixed report or exchange (e.g. the zone in CQ WW) or this QSO's serial number, which moves to the next one as soon as the QSO is logged (editable by hand; EFFACER resets it). As soon as the call is typed: DUPE blinking on a red background when it is already in the contest log on this band (hover: QSO time, other bands); nothing shown = valid QSO. Indicatifs probables (likely calls, under the contest macros), as in the TRX SSB page: typing 2 characters or more lists the calls of the contest log, then of the Super Check Partial list, that contain them (green: not yet worked, struck through: dupe on the band; click = into the call box); empty box: the stations spotted in CW on the TRX band (DX cluster, Reverse Beacon Network), click = call and TRX on its frequency with control. Spot cluster: each logged QSO is also spotted on the DX cluster under your operator call (see the TRX SSB page). QSOs go into the general logbook (contest id, sent and received exchanges, under the TX call); on the right: list of the contest QSOs, counts per band, dupes, rate (10 min and 1 h). Depuis (since): start date taken into account (last 3 days by default); ADIF: .adi file of the contest QSOs; CABRILLO: the contest file (its QSOs only) to send to the organiser. The serial number moves on at each logged QSO.
  • During a CW transmission (macro, remote key or key plugged into the TRX), the frequency stays red until the end of the message, even when the TRX break-in returns to receive between letters (1.5 s more after the last element).
  • Clé → TRX OFF (when the page loads): practice, local sidetone only, nothing is transmitted. ON with control: your key keys the TRX. The yellow light follows your key; the TX badge lights when the club TRX transmits your keying.
  • Réglages (settings): key (iambic B paddles, iambic A, or straight key), speed (5 to 50 wpm, the page keyer's own speed, independent of the macro speed), weight (50 % = normal), swap dot / dash, sidetone pitch, volume and audio output (e.g. headphones, separate from the TRX audio).
  • Connecting your key to your PC:
    • USB adapter (left / right Ctrl): paddle → USB adapters that appear as a keyboard (VBand / Vail type): left Ctrl = dot, right Ctrl = dash.
    • Keyboard keys: two keys of your choice (click the box, then press the key).
    • MIDI adapter: click the Dot box then touch the dot paddle, same for the dash (MIDI notes or controllers).
    • USB-serial cable (DSR / CTS): the classic contest-software wiring: dot contact on DSR, dash on CTS, common on DTR (set high by the page). Choisir le port…; Chrome or Edge. Detailed wiring below.
    • On-screen paddles: the • and — buttons (mouse or touch screen), always available.
  • Connecting dual paddles (or a straight key) to your PC. A key is only a switch: neither the sound card nor a USB socket can read it as is, a small USB interface is needed. Nothing goes to the sound card, and there is nothing to install (no server at the club, no software at home): the path is key → USB interface → your PC (TRX CW page) → Internet → server → club Station page → FTX-1.
    • USB → RS-232 adapter with a male DB9 plug (CH340, PL2303 or FTDI chip; the common clear-blue model is fine). In Device Manager (Ports COM & LPT) it must show without an exclamation mark (Prolific "PL2303HXA phased out" / code 10: counterfeit chip refused by the recent driver → another cable or an old driver). On a female DB9 screw-terminal plug ("DB9 breakout"), screw the key's 3 wires:
      • Key common (often called "GND") → pin 4 (DTR: voltage switched on by the page)
      • Dot → pin 6 (DSR: input read as "dot")
      • Dash → pin 8 (CTS: input read as "dash")
      The common goes to pin 4 (DTR), not pin 5 (GND): on ground no voltage would reach the inputs. The other pins are not used. Pin layout, adapter's male plug seen from the front: top 1 2 3 4 5 (left to right), bottom 6 7 8 9.
    • Identifying the wires: 3.5 mm stereo jack: tip = dot, ring = dash, sleeve = common; bare wires: multimeter on "continuity", one probe on the common, press a paddle and find the wire that beeps. If in doubt, connect at random and tick Swap dot / dash if needed (no risk).
    • Test without the key (CLÉ → TRX OFF): CW station → USB-serial cable (DSR / CTS) → Choisir le port… → the CH340 → "port open"; a paper clip between pins 4 and 6 gives dots, between 4 and 8 dashes (local sidetone + Key light).
    • Not suitable for dual paddles: 4-wire USB "TTL" cables (red +5 V, black GND, green TX, white RX), USB → 3.5 mm "console" jack cables (tip RX, ring TX), and the 6-wire FTDI TTL cable (one CTS input only: straight key only, key between CTS and GND). "USB CW cables with jack" sold to let software key a TRX do the opposite (output to the TRX).
    • Other options: a ready-made paddle → USB adapter of the VBand or Vail type (seen as a keyboard: "USB adapter (left / right Ctrl)"); or an Arduino Pro Micro (ATmega32U4) with a jack: ground → GND, dot → A2, dash → A3 (same setting).
  • CW spot clicked in a band map (front-panel BAND MAP, where the mode is written next to the spot, or the digital-modes band map): the TRX tunes to it in CW, the CW tab is shown and the call goes into the QSO box (other station), also in the CW station page (in a contest: in the log's Indicatif box, dupe checked, ready for Enter), which comes to the front if it is open. <CALL> macros use it at once.
  • Macros and key: during a macro (F1…), touching the key stops the macro and your key takes over the TRX. So you can call CQ with F1 and answer with the key.
  • What you key is shown in the CW receive window, in transmit colour like macros (text rebuilt from your dots and dashes, without going through audio decoding).
  • Esc stops the transmission; keying resumes at the next press after a short pause.
  • Keyboard keys are only taken while the CW tab is shown. Keep the window visible while operating (Chrome slows hidden tabs). Turn the TRX audio down while keying so your own delayed signal does not disturb you.
  • Conditions and safety: the same as macros (control, allowed band and power, TRX in CW without SPLIT, maximum duration without a pause); the Station page releases the key if your data stops arriving (0.3 s), cuts a key held down more than 5 s, and ends the burst after a pause. The CW keying port (DTR) must be open on the Station page (section 18); otherwise the refusal is shown.

12.7 SSTV

• Receiving: pictures arrive by themselves (VIS code) and are drawn line by line. Martin, Scottie, Robot and PD modes. The gallery keeps the last 12 (click = show); PNG saves the picture shown to your PC.
• Preparing a picture: Images du PC… (pictures from your PC) (or drag and drop a picture), CQ card, test pattern or received picture; it is cropped to the format of the chosen mode. The vertical line between Réception SSTV and Émission can be dragged to set their width (double click: half and half). Recommended size: 800 × 600 pixels (landscape 4:3, JPG or PNG, under 5 MB): no cropping in Robot 36 / 72, 1 to 3 % cut left and right in the other modes; keep the essentials in the centre and leave room at the top and bottom for the texts. Your pictures come from your PC (anywhere, over the internet) and stay in your browser (10 at most, the oldest is removed); when transmitting, only the transmitted picture goes through the server, just to build the signal, without being saved there. Three text lines (top, centre, bottom) with the tags <CALL>, <MYCALL>, <RST>…; text size and colour. Right click a thumbnail: remove it.
• ▶ Écouter (play) plays the signal on your PC (without transmitting); WAV saves it as a file.
• Transmitting: with control, TX VFO in DATA-U, Émettre (transmit) sends the picture shown (in the format of the chosen mode) to the server, which builds the signal and hands it to the Station page; the TRX transmits about one second later. During transmission, the part of the picture not yet sent is darkened, the red line follows the current line, and the note under the picture gives the line and the time left. ■ Arrêter or Esc stops. Same safety checks as RTTY (bands, power, SWR, link). Duration: from 37 s (Robot 36) to almost 5 min (PD 290); the limit of the other modes does not apply, but the server refuses a mode longer than its maxSstvSeconds setting (300 s by default). The TRX transmits continuously for the whole picture: reduce power (25 to 50 % advised).

12.8 Synchro

A monitoring tab: it shows whether the clocks and the link are in step. There is nothing for you to set.

12.9 QO-100

QO-100 is a geostationary satellite reached on 2.4 GHz with an up-converter. The FT8 · FT4, RTTY and CW lists offer « QO-100 · FI 2 m / 70 cm » (IF 2 m / 70 cm): the frequency to set on the TRX before the converter, to uplink on 2400.040 MHz (FT8 / FT4), 2400.025 MHz (CW) or 2400.090 MHz (RTTY). Example: FT8 on 432.540 MHz with the club's 70 cm converter. Only the IFs the connected TRX can reach are offered (FTX-1).

13. Correspondent, macros and tags

The Correspondant line (under the digital-mode tabs)

Macros (RTTY, JTTY, CW) are ready-made texts, on a row above the text box: F1 to F12 in RTTY and CW, F1 to F8 in JTTY.

• A macro starting with <TX> (red edge on the left; this is the case for all default macros) is transmitted at once when clicked or with its F1… key, then the TRX returns to receive.
• Shift+click: adds the macro to the text to send without transmitting, to build a message and then « Émettre ».
• A macro without <TX> is simply added to the text (in CW too: the original macros have <TX> and go out at once).
• Right click a macro (or ✎): edit it — name, text, preview, back to the default text. Your macros are stored on the server, for you only.
• If a macro contains <CALL> while no correspondent is chosen, nothing is sent.

14. Logbooks (station logbook)

Logbooks tab (cyan button, left of Log QSO and Synchro): the station logbook, shared by all members. It can upload QSOs to LoTW, eQSL, Club Log and QRZ.com, export them as ADIF or Cabrillo, and forward them over UDP to logging programs on the PC (Swisslog, HRD Logbook, Log4OM, N1MM Logger+…).

🌐 Network — shared log (Synchronisation ▾ → 🌐 Réseau, administrators; since version 0.42.0), in the way of N1MM: several stations, each with its TRX and its own Remote Station server, share one log and one series of contest serial numbers (RTTY, CW and SSB pages). Every server keeps a complete copy of the log. Mode Hors réseau (standalone, default), Poste (linked to the master) or Maître (master); list of masters by priority (e.g. remote.op0p.be then secours.op0p.be) and the network key, the same everywhere. Stations connect to the master over HTTPS (port 443): nothing to open at home, even behind a CGNAT. If the master stops answering, the backup master takes over after 30 s, and hands back to the master when it returns (after sending it the QSOs made meanwhile). With no master reachable, a station carries on alone: its serial numbers are then provisional (orange message). The screen shows the state (master active or waiting, links, QSOs received and sent, backlog). On the server, the logbook is a SQLite database: each QSO is saved in a few milliseconds, even with hundreds of thousands of QSOs (hover the QSO count above the list to see it).

Large logbook on another screen: the dashboard already opens on the logbook; clicking LOGBOOKS again (logbook already shown) opens it in its own window, to put on a second screen (it reopens at the same place and size). It shows all columns (TX call, OP, references, contest, LoTW, eQSL, Club Log, QRZ…) and up to 1000 QSOs (300 in the dashboard); a click on a row opens the full QSO form (DÉTAILS QSO). This window has its own search, filters, TX CALL box and Synchronisation / Exporter menus, independent of the dashboard's; a QSO logged elsewhere shows up at once. It uses the dashboard's connection: if the dashboard is closed, reopen it and click LOGBOOKS twice.

📊 STATISTIQUES DXCC (large logbook window, right of DÉTAILS QSO), in the way of Swisslog: for the chosen TX call (or all), one row per DXCC entity (prefix – country), all 340 entities, even those never worked (Pays list: all, worked, not yet confirmed, never worked) and, under each band (always 160, 80, 60, 40, 30, 20, 17, 15, 12, 10, 6 m and SAT for QO-100, plus 2 m, 70 cm… if there are QSOs), one column per mode: SSB, CW, RTTY, FT8, FT4, FT2 (and « Autres », other modes, if any). Cell C = confirmed (LoTW or paper QSL), W = worked, - = not yet. Below, the summary: for each band, the number of entities worked / confirmed in each mode and in total, then the Total row (all bands). The Mode list limits the table to CW, phone, digital or one mode (one column per band); sort by prefix, country, continent or number of bands; country search. A click on a cell goes back to the logbook, filtered on that TX call, entity, band (and mode). WAE entities (Sicily, Shetland…) count for their DXCC entity (Italy, Scotland…). ↩ CARNET (or Esc, or clicking 📊 STATISTIQUES DXCC again): back to the logbook.

14.1 Logging a QSO

The QSO form is hidden by default: the logbook takes all the room, the search (call, name, operator) stays visible. The yellow DÉTAILS QSO button, at the start of the search bar, shows it (new QSO); click again to hide it. A click on a QSO in the list opens it with that QSO; it hides 2 seconds after saving (or at once with Annuler).

The form at the top of the tab:

Without leaving the RTTY, JTTY or CW tab (in RTTY, the QSO line and LOG ↵ log without a form; the Log macro opens the form): the Log QSO button (next to « Émettre » in JTTY and CW, and on the tab row, right of Logbooks) opens a form already filled in: callsign, first name, QTH, locator and RST, frequency (in RTTY: the signal frequency) and mode, power, start time (when the correspondent was chosen) and end time. Correct if needed, then Enregistrer dans le carnet (save to the logbook). In FT8, this form opens by itself at the end of the QSO; a macro containing <LOG> also opens it.

In FT8 · FT4 · FT2, at the end of the sequence, a small « QSO terminé » (QSO finished) window summarises the QSO (callsign, locator, mode, frequency, reports, times): Enregistrer dans le carnet saves it, Ne pas enregistrer (don't save) closes it. The Paramètres Logbook (logbook at end of QSO) list in the FT8 bar (right of "Activité") chooses what happens: MANUEL (ask me before saving: this window), or AUTOMATIQUE (as soon as RR73 is received or 73 sent — or RR73 sent / 73 received when you were calling CQ —, like WSJT-X "Log automatically": no window). Even in automatic mode, the form below the macros still lets you save, correct (Modifier le QSO) or delete a QSO by hand; the QSO then goes into the logbook on its own (other station's name and QTH included when known) and a message confirms it. Without the automatic sequence, or for a forgotten QSO: Logbooks tab, type the call, ⇩ TRX (TRX frequency and mode), the reports, then save.

14.2 The QSO list

• The list shows the last 300 QSOs. The Rechercher (search) box finds a callsign, a name or an operator; the number of QSOs found is shown next to it.
• Click a row: the QSO opens in the form. Its author with control (or an administrator) can edit or delete it; everyone else (members without control, listeners, other operators) sees it read-only (« Fermer » closes it). Nobody can ever edit or delete a QSO logged by another callsign, except administrators.
• Columns: date, time, callsign, band, frequency, mode, reports, name, QTH, locator, DXCC country, prefix, TX call, operator, references (IOTA, POTA…), Contest (contest during which the QSO was made, Cabrillo identifier such as CQ-WW-SSB, filled by the TRX SSB / TRX CW pages and the RTTY contest; hover: sent and received exchange), upload states (LoTW, eQSL, Club Log, QRZ).
• Right-hand columns off screen: horizontal scroll bar at the bottom of the list (the list fits the screen height: right-hand scroll bar to go down the logbook), or Shift + mouse wheel over the list.
• VFO A / B of the STEP row (VFO tuned by the wheel, arrows and bands): A on dark green, B on dark pink, only one at a time.
• Small filter in each VFO display (left of the frequency, when the display is wide enough): the VFO's [BW] and [SFT], passband in orange around 1500 Hz (700 Hz in CW) shifted by the SHIFT, edges in orange; it follows the BW and IF SHIFT settings of the left column (Icom: width and TWIN PBT).
• MODES row of the dashboard: the chosen mode (its page opens separately) stays marked on an azure background, even after a reload.
• Column order: click a column title and, holding the left button, drag it elsewhere (a blue line shows where it will go). Order remembered in your browser; double-click a title: original order.
• Column width: drag the right edge of a column title (double-click: original width). Setting remembered in your browser.
• Filters: the ▾ next to each title offers the values of that column (dates, bands, modes, countries, TX call, upload state…) with their QSO count. A choice filters the logbook (the ▾ becomes ●); several columns combine; ✕ Filtres (filters) removes them all.

14.3 Exporting

14.4 Synchronisation (LoTW, eQSL, Club Log, QRZ)

Synchronisation ▾ menu: it uploads the logbook QSOs to the confirmation websites. One window per service, as in Swisslog. Administrators handle every callsign (club and members). Each member who transmits under their own callsign uses it for their own QSOs: the callsign is theirs and cannot be changed; they enter their own credentials (kept on the server, never shown, usable by nobody else), can tick « send each new QSO automatically » (not shown for ON5VL / OR0L: the club's automatic upload is set in ⚙ Configuration), and their QSOs never go to the club accounts (nor the club's to theirs). A refused password only stops that callsign.

1. Choose the service: Synchronisation LoTW…, Synchronisation eQSL…, Club Log… or QRZ….
2. Détails (details) tab: choose the callsign (TX call) whose QSOs are uploaded (the current TX call is suggested).
3. Just below, the yellow « Identifiants <service> de <indicatif> » (<service> credentials of <callsign>) box shows the credentials that will be used: login, password, key… A note says whether they belong to this callsign, come from the club configuration, or what is missing. Complete them if needed, then Enregistrer pour cet indicatif (save for this callsign). Passwords stay on the server and are never displayed: a field left empty keeps the stored value, ✕ deletes it, 👁 shows what you type.
4. Optional: date range, Renvoyer aussi les QSO déjà envoyés (also resend QSOs already sent), Temporisation (delay in seconds between two QSOs, so as not to be blocked by the website). Club Log: « Effacer le log ClubLog existant » (clear the existing Club Log log) replaces the whole online log (only use it if this logbook is complete). The number of QSOs to upload is shown at the bottom.
5. Télécharger (upload): the upload starts; the Traitement (processing) tab shows the progress and the report, QSO by QSO. Arrêt (stop) interrupts it; Fermer (close) closes the window: the upload continues on the server and its progress stays visible below the logbook list.

• Club callsigns and personal callsigns: the credentials in the general configuration (14.5) are only used for the club callsigns (ON5VL, OR0L). A personal callsign (ON6DP…) needs its own credentials, otherwise its QSOs are marked « non configuré » (not configured). An upload mixing several TX calls is done group by group, each with its own credentials.
• LoTW operations: export, sign with TQSL, upload, read confirmations, status. Confirmations only reads the confirmations received (★ in the list). With the server on the VPS (no TQSL): Exporter pour TQSL (.adi) (export for TQSL), sign the file with TQSL on the club PC, then Marquer comme envoyés (mark as sent).

14.5 Configuration

Synchronisation ▾ → ⚙ Configuration… (administrators): the general settings, in tabs CLUBLOG, eQSL, LoTW, QRZ and UDP.

• « Télécharger automatiquement les QSO lors de leur enregistrement » box (upload QSOs automatically when they are logged): every new QSO under a club callsign is uploaded to that service by itself.
• Club logins and passwords (👁 to see them while typing), delay, and Tester (test) to check the connection to the service. The window only shows « enregistré » (stored) for passwords; leaving the field empty keeps the value, ✕ deletes it.
• QRZ tab, Recherche des correspondants (correspondent lookup): login and password of a QRZ.com account. As soon as a correspondent is chosen (click on a callsign, Correspondant line, logbook form), their first and last name (logbook form), town and, with an XML subscription, locator are filled in automatically (empty boxes only; the logbook form's ⇩ QRZ button, next to the locator, fetches them again and replaces what is written), with a « QRZ.com : … » note below the bands.
• QRZ tab, Indicatif / Clé API table (upload to the QRZ logbook): one line per callsign (TX call) with its API key; + Ajouter un indicatif (add a callsign) adds a line, ✕ removes the key.
• UDP tab: forwarding of each QSO to logging programs. One line per destination: Actif (enabled) box, Nom (name), Adresse (address), Port, Format (WSJT-X « Logged ADIF », WSJT-X « QSO Logged », N1MM Logger+, raw ADIF); the + WSJT-X (port 2237), + N1MM Logger+ (port 12060) and + ADIF brut buttons add a pre-filled line (address 127.0.0.1); ✕ removes it.

16. Common problems

17. For administrators

A click on the ● Station lamp opens the TRX du club (club TRX) menu:

Administrators also have access to the logbook Synchronisation menu (14.4 and 14.5), to the export of every TX call, and can take back control (section 6). They can save the club setting of the TRX equaliser (TRX EQ button) and open the statistics page (📊 STATS button). Management of members, passwords and the server is described in the Administrator guide (GUIDE-ADMINISTRATEUR.md, project repository, in French).

18. The club PC (Station page)

For club managers. The PC connected to the TRX opens https://remote.op0p.be/station in Chrome (Web Serial). On Windows 10 / 11, the RemoteStation-Setup installer does everything needed: « Remote Station - Page Station » shortcut (Chrome with the right settings), start with Windows, no sleep; it can also install the server itself on that PC (see LISEZMOI-WINDOWS).

The Station page is reserved for administrators: the first time it is opened on a PC, log in with the callsign and password of an administrator. That PC then stays authorised for one year (renewed each time the page is opened), until « Se déconnecter » (log out). A non-administrator member is refused. The club PC's browser, which keeps the station token, also logs back in by itself.

🔒 The Jeton de la station (station token), Vitesse (bps) (speed) and Bits de stop (stop bits) fields are locked, to avoid mistakes. Only ON6DP and ON4LUC, logged in to the Station page with their callsign and password, can change them: « Se déconnecter » (log out) at the top of the page, then log in again with that callsign. The list is set in config.json (stationEditors). Choosing the model, port and audio remains free.

FTDX101D / MP: USB audio in stereo (MAIN receiver on the left, SUB on the right). In dual receive (DUAL RX), the Station page sends both channels: in RTTY, decoder B reads the SUB receiver, with its own waterfall to the right of A's; listening gets the mix of both, as in headphones. In single receive, one waterfall, as on the other transceivers.

1. The station token is fetched from the server automatically as soon as an administrator is logged in to the page (nothing to copy). Choose the TRX model and its CAT port (the first time). FTDX10 and FTDX101: CAT RTS OFF in the TRX menu (otherwise the link drops every 2 s). FTX-1: the Enhanced COM Port (CAT-1), and on the TRX the RPTT SELECT and PC KEYING settings at OFF (factory default): transmission is controlled through CAT.
2. Activer l'audio (enable audio) and choose the TRX sound input ("USB Audio CODEC" or "USB Audio Device" depending on the TRX); the level bar must move. Pick the card itself, not « Par défaut - … » / « Communications - … »: those Windows entries switch to another card when another TRX is plugged in (the page replaces them with the real card anyway).
3. Sortie son vers le TRX (sound output to the TRX, for FT8 / FT4 / FT2, RTTY, JTTY transmission): the TRX's USB sound card ("Speakers (USB Audio CODEC)"…), chosen automatically when possible. Never the PC speakers. The TRX must take DATA modulation from USB (TRX menu). Set the transmit level so that ALC stays low. Optional limiter: with "digiAlcMax": 8 in config.json, the Station page lowers that level by itself as soon as ALC goes above 8 % during a digital transmission, and keeps the reached level for the following transmissions; it never goes back up by itself. By default (0), no limiter. Transmissions start on the server clock, even if the Windows clock is off.
4. Keep the Station page alone in its window; open the dashboard with its « Ouvrir le dashboard dans une autre fenêtre » (open the dashboard in another window) button.
5. Chrome → Settings → Performance: always keep remote.op0p.be active; Windows: sleep set to Never.

Two TRX (or more) plugged into the same PC, each on its own USB port: select each model once on the Station page, choose its CAT port and its sound card (input and output). The page remembers them per model. An administrator then switches from one to the other from the STATION menu of the dashboard (section 17): the Station page restarts with the other TRX and reopens its port and sound card within a few seconds. Never during a transmission.

Station page controls

Frozen TRX sound card (no more audio)

The TRX's built-in USB sound card sometimes freezes silent: empty level bar on the Station page, silent waterfall (only a hum at the far left), nothing to listen to. After 45 s of silence with the TRX connected, the Station page shows it in orange, and so does the dashboard (under « Écouter le TRX », with a message to the station managers and to whoever has control).

• Relancer la carte son du TRX (restart the TRX sound card): button on the Station page, or, for ON6DP and ON4LUC, the « Relancer la carte son » button of the dashboard alert and the TRX menu (click the station lamp). The USB sound card is restarted on the club PC, like « Disable / Enable » in Device Manager; audio stops for about ten seconds, the TRX stays on, the CAT port is not touched. Refused while transmitting.
• Once, install the sound card helper on the club PC: « Télécharger l'assistant carte son » link on the Station page (while it is not installed), unzip, double-click installer-carte-son.cmd and accept the administrator prompt. It starts with Windows, listens only on the PC itself (127.0.0.1:18099) and only obeys the remote.op0p.be Station page. The first time, Chrome may ask for access to « local network devices »: Allow. The Station page shows « Assistant carte son : en marche ».
• Automatic restart: with the assistant installed, the Station page restarts the sound card by itself after 45 s of silence (receive only, never while transmitting), at most once every 10 minutes.
• Assistant version 2: at every Windows start it also turns off USB power saving (USB selective suspend, and "Allow the computer to turn off this device" on USB hubs and USB sound cards), a frequent cause of a frozen sound card. Run installer-carte-son.cmd once more to upgrade from version 1.
• Assistant version 3 (0.37.175): when Windows puts the TRX sound card in error ("USB Composite Device" in error, "USB Audio CODEC" gone from Device Manager), a simple restart is not enough: the assistant removes it and has Windows detect it again (like "Uninstall" then "Scan for hardware changes"). It watches this sound card itself every 20 s, even with the Station page closed, and repairs it on its own (at most once every 5 min). The "Assistant carte son" line of the Station page shows the TRX sound card state and the last repair. To upgrade to version 3: download the assistant again and run installer-carte-son.cmd once.
• Assistant version 4 (0.37.187): also sets the Windows clock to the millisecond, like NetTime (Windows Time service set on be.pool.ntp.org, europe.pool.ntp.org and time.cloudflare.com, polled every 1 to 4 minutes), at start-up, every hour and on request (Synchro tab, ⟳ Mettre à l'heure). The "Assistant carte son" line of the Station page shows the measured offset. Uninstall NetTime from the club PC to avoid two competing settings.
• Never another sound card instead of the TRX's: if the TRX sound card has vanished from Windows, the Station page no longer takes the PC sound ("Stereo mix", Realtek speakers…) instead; it shows the "TRX sound card missing" alert, asks the assistant to repair it and restarts on its own as soon as the card is back. A TRX audio output that disappears is closed (digital transmission refused) instead of playing through the PC speakers. Choosing a PC sound card by hand shows a warning.
• If the restart is not enough: switch the TRX off and on (the FTX-1 cannot be switched on by CAT).
