What's new in SatMe

• APRS: a more tenacious decoder — a frame noise spoiled by one or two bits is mended (only where the demodulator hesitated, with a right FCS, real callsigns and a single possible answer: noise alone gives nothing); the sound card's decoder also hears FX.25 and IL2P (frames protected by a Reed-Solomon code), without any setting. /api/aprs counts the frames heard clean, mended, FX.25 and IL2P (decodeur) and lists the last ones marked « corrigée 1 bit », « FX.25 », « IL2P ». Receive only.
• SDR: the Signal Hound BB60 (BB60C, BB60D) as a receiver — SDR tab, Récepteur › Signal Hound BB60: 9 kHz – 6 GHz over USB 3, through the library of Signal Hound's SDK (installed by you; SatMe does not ship it). Reference level, gain and attenuation; Détecter reads the model, serial number, firmware, temperature and USB supply; while receiving, rate, filter, losses and overloads live. Unplugged, it opens again by itself. Library missing: the card says so, nothing else changes. Receive only.
• Your site: the setup used for what is live. With Envoyer vers un site web › En direct › Station and Description du montage ticked, the « Station » line also says which pieces of the setup are in use now (those the Montage tab lights: dish, LNB, MiniTiouner, rig…, by their ids only) and, during DATV, the LNB's polarisation (V 13 V, H 18 V): your site can draw the setup in use, live, for each activity. Nothing else is sent, never a port name or an address.
• FT4 / FT8 on a satellite: what was missed on RS-44 (27/10/2026) — the 16:24 UTC pass carried FT4 from 16:28 to 16:41; read again by SatMe, its recording gives 153 FT4 messages (−4 to −12 dB). They were not read because the listening was in FT8 and Re-decode from the recording offered FT8 by default. Now: the + FT4 (or + FT8) box beside the FT8/FT4 tab's mode, ticked by default, decodes the other mode too in its own slots (its lines marked FT4, kept with the pass, never an automatic answer); the banner says « du FT4, pas du FT8 » after 4 slots; the journal reads again in FT4 + FT8 by default, with a second's margin either side of the slots.
• CAT Doppler by 4 Hz steps while FT8/FT4 listens — the loop corrected the downlink by 20 Hz steps: on a low satellite (20 Hz/s) every signal slides then jumps 20 Hz each second, a sawtooth FT8 does not survive at all and that costs FT4 3 to 5 dB. While FT8/FT4 listens, the downlink follows by 4 Hz steps (five writes a second at most, the uplink unchanged). The decoder runs below the other tasks and the other mode is skipped when the PC is behind, so the sound card is never starved.
• Journal: digital zones — where a recording holds narrow, regular bursts, a violet zone on the timeline with its name (FT4, FT8, numérique), as the SSTV pictures in orange. A click chooses it (on its violet strip: Options › Digital opens on it); Decode reads it at once in FT4 and FT8 and lists the messages with their times; Search for digital reads an older recording again and decodes each zone; 🌐 Publish on the site sends the pass's FT4/FT8 messages (type ft8-passage, like the FT8/FT4 tab's 🌐; nothing when set to « Jamais »).
• QO-100: Sun outages — twice a year, a few minutes a day, the Sun passes behind QO-100 as seen from your station and drowns the downlink. The QO-100 tab says so while it lasts ("☀ Éblouissement solaire en cours jusqu'à 12:47 — normal, pas une panne") and when it comes near; Pointage has the table of the coming days (local time and UTC, minutes, the time of the maximum). The threshold comes from your dish (Mesures › Bruit solaire, otherwise 80 cm). « Pourquoi rien ? » (narrow band, DATV) says it instead of blaming the LNB. Also a free pointing check: the noise peaks at the predicted time when the dish is aimed right. For a site: GET /api/qo100/soleil, and soleil in the web publishing's Balises QO-100.
• The ISS with the naked eye — the 👁 ISS chip in the Prochains passages title (Suivi): the next visible pass (dark sky, ISS in sunlight, 10° up at least) and its brightness; a click opens three days: where it appears, culminates and vanishes (🌑 into the Earth's shadow), its estimated magnitude. For a site: GET /api/iss/visible?jours=3.
• APRS: Messages — a tab beside Trophées: the messages addressed to your callsign (any SSID) and the bulletins, those received through a satellite marked, an unread badge, an optional browser notification (unticked by default). Receive only: no acknowledgement is sent.
• Rotator on the Sun or the Moon (Réglages › Rotor) — ☀ Soleil and ☾ Lune point the rotator once, on a click, at the body as seen from here (or "sous l'horizon"); suivre re-aims it every 20 s until stopped. Within the rotator's limits; nothing moves by itself. For aligning a dish on the Sun's noise.
• Frequencies: SatPC32 and Gpredict (Réglages › Satellites) — export the favourites, the satellite followed or all of them as Doppler.SQF or .trsp files; import such files: the frequencies join their satellite's list, the names with no satellite found are listed.
• Sound lost on an overloaded PC: seen, filled, told — the sound card is read by a thread of its own (highest priority, a second of buffer instead of 85 ms) and the decoders have theirs behind a 10 s queue: a slow decoder no longer makes the card overrun (test under load: 0 ms lost instead of 908 ms over 4 s). Sound lost all the same is replaced by as much silence (2 s at most per hole): an SSTV picture keeps its rows in place with a grey band, instead of a torn, shifted picture; FT8 keeps its slots; the recording lasts as long as the pass. The card's clock drift is never taken for a hole. Told in the card's state (« son perdu : 1,2 s (3 trous, dernier 21:14) »), in « Pourquoi rien ? » (« son perdu : 19,7 s pendant ce passage — PC surchargé (charge 34 pour 12 cœurs) »), on the picture (« son perdu 1,2 s ») and in the log.
• Recordings: whole sound or not — the Son tab's list marks son perdu 3,2 % a recording shorter than the time it lasted; each new WAV has its .temps sidecar (start, stop, samples, holes filled). Detail: GET /api/son/bilan.
• Telemetry › Paquets: a TS-2000's 9600 output on a sound card — a new Source Carte son : bande de base 9600 (TS-2000, prise ACC2) beside the SDR receiver: the rig demodulates (its discriminator, Doppler corrected by the CAT), SatMe reads the G3RUH, GMSK or FSK frames from 1200 to 9600 bit/s, the SSDV and Geoscan pictures, whatever the polarity. Choice of the card (the Son tab's, or a separate one), level meter, and wiring help: ACC2 pin 3 (MANO) to the line input, ground on pin 4, menu 50F at 9600. Receive only; Essai makes such a sound.
• Rewind the waterfall — the SDR receiver's, the narrow-band transponder's (QO-100) and the DATV wide band's waterfalls have a ⏸ button: paused, the wheel, a drag (finger or mouse) or a slider go back through the last 10 minutes, a tape says "−2 min 15 s · 14:03:21 UTC", the pointer or the finger gives the time and frequency of the row touched; the waterfall keeps recording, Direct ▶ snaps back to live. Kept in the browser, one byte per point (1.3 MB per waterfall at most).
• Log: confirmed by source — the QSL reçues card counts the grids and satellites confirmed by LoTW or paper (what VUCC takes) and, apart, by eQSL only; the Locators page tells them apart (green / violet outline, "LoTW✓ papier✓ eQSL✓") and the VUCC award gives the confirmed count. eQSL is never counted as LoTW.
• Log: a contact edited after its upload — marked "✓ modifié ⟳" with what changed, kept across restarts, never uploaded again (Wavelog would create a duplicate or skip it). A click: the list to fix in Wavelog, or, with a Wavelog 3.1+ APIv2 token (Réglages), the update of the contact found in Wavelog, edited fields only.
• « Pourquoi rien ? » (why nothing?): a line that names the fault — SSTV, APRS, FT8 / FT4, telemetry packets, DATV, QO-100's narrow band and the wide band spectrum: when nothing is decoded, the tab says in one dated line the most likely cause — « IC-9700 sur 145,990 FM (lu il y a 3 s) — la SSTV de ISS est sur 145,800 FM » with Accorder (it only chooses the transmitter again, never a transmission), the wrong mode, a dead sound card (no samples) or a merely quiet one (« −72 dBFS sur 10 s »: a squelch shut, not a fault), the satellite below the horizon and its next pass, the SDR stopped, the node silent, DATV not locking (LNB on 13 V for the wide band, the beacon's MER), QO-100's beacon unseen.
• The rig recovers by itself — IC-9700 / IC-9100 / IC-910H (USB or network) and TS-2000: a rig that stops answering is no longer flooded with commands; SatMe tries again after 2, 4, 8, 16 then every 30 s (the same port reopened, RTS and DTR always low), as soon as a vanished USB port is back, and sets the rig up again once it answers — never its transmitter. The status line says « IC-9700 muet depuis 2 min — nouvel essai dans 20 s ». A refused command (FA, ?;) is a refusal, no longer a success; a frequency outside the rig's bands (IC-9700: 2 m, 70 cm, 23 cm) is no longer sent, with the reason.
• APRS: a map of the stations heard — the APRS tab opens on a map (no internet needed, OpenStreetMap if you choose): each station with its APRS symbol, its callsign, an arrow for its heading and its trail (1 to 48 h), a ring telling how it was heard — direct, through a digipeater, through a satellite (the ISS…) or from the internet (dashed) —, your station in teal. On a tablet: drag, pinch, tap. Above it, the day's figures: stations heard, heard via satellite, farthest heard direct, packets per hour.
• APRS: the list and a station's card — beside the map, the list sorted (last heard, distance, callsign) and filtered (RF only, via satellite, 1 h to 48 h, mobile, fixed, weather, digipeaters, iGates, objects, search); with Via satellite, stations grouped by pass ("Reçus via ISS pendant le passage de 14:32"). A click opens the card: the symbol in words, QRZ.com and aprs.fi links, comment, distance and bearing, locator, course, speed, altitude, when it was last heard each way, the path, weather, message, telemetry and the raw packet. The last 48 hours survive a restart. The KISS radio, the trophies and the raw frames are below.
• Web publishing: QO-100's wide band and your reception on your site — a new line Bande large QO-100 (DATV) under En direct (unticked by default) sends your site, every 2 s (1 to 10 s) while the DATV receiver is on, the DATV tab's strip: the ground station's public spectrum made 512 points, the signals found and their names, and your reception over it (frequency, symbol rate, lock, MER) — 2 to 4 KB each time (type direct-large). Spectre de la bande large must be ticked in the DATV tab; the connection to the ground station stays SatMe-PC's only one, your site's visitors never connect to it.
• Log: ADIF check before export — under Exporter en ADIF, a Contrôle ADIF line counts what LoTW, eQSL or Wavelog would refuse (blocking: no uplink frequency so no BAND, out-of-band frequency, missing or unknown mode, forbidden characters in the callsign) and what deserves a look (warning: unusual callsign, malformed locator — left out of the export —, satellite missing from the LoTW list SatMe knows with the expected name — ARISS for the ISS —, accents in the name, QTH or note, duplicate within 2 min, date in the future, contact without callsign not exported). Unfold the list, click a line: the contact opens for editing.
• More accurate ADIF export — FT8 goes out as MODE=FT8 (no longer MFSK/FT8), FT4 and JS8 as MFSK, PSK31 as PSK, FreeDV, C4FM, D-STAR and DMR as DIGITALVOICE; the callsign always in capitals; the ISS goes out as SAT_NAME=ARISS, LoTW's name; a malformed locator is no longer exported. A grid line in the locator field ("JN06,JN16", from a Wavelog import whose station profile spans two squares) goes to MY_VUCC_GRIDS / VUCC_GRIDS instead of an invalid MY_GRIDSQUARE (flagged "fixed at export" by the check); the import now files such a line as the station's squares, not its locator.
• Log: QSLs received (LoTW, eQSL, paper), read from Wavelog — a QSL reçues card: confirmed and waiting per service, Relever les QSL (new contacts; the whole log once a day) and tout relire (read everything again); in the contact list, small pills under the callsign ("LoTW ✓", "eQSL …", "papier ✓") and the en attente seulement (waiting only) box. Read only, with the online log's key: SatMe-PC logs into neither LoTW nor eQSL and keeps none of their passwords. Wavelog only learns of a confirmation after its own LoTW/eQSL sync.
• DATV: « Émis par la station » (sent by the station) — the provider and service names read in the stream (SDT) are the transmitting station's — its callsign, often its transmitter's firmware (Pluto…) —, never your receiver's: the line now says so.
• SSTV: automatic AI denoising on the re-decoded version too — when Re-décoder chaque image à la fin keeps a better version, the automatic AI processes it in turn (when the picture qualifies) instead of staying on the first one.
• Compact AMSAT pill (Suivi tab) — a single line under the satellite's name: a coloured dot for the status, 👂 ✓ / 👂 ✕ for "heard" / "not heard", ⟳ for automatic reporting.
• An Images tab: every picture received in one place (workspace Carnet). SSTV, SSDV (SO-127, IO-86, cubesats) and Geoscan pictures together, newest first; chips Toutes · SSTV · SSDV · Geoscan and the satellite filter. Each thumbnail tells its kind, satellite, time and, for SSDV and Geoscan, the packets received and missing or complète; a picture under way grows live during the pass. An SSTV picture opens in its viewer with its retouches, an SSDV or Geoscan one in a window with its packets by pass, ⤓ PNG / JPEG and 🌐. It is also the SSTV › Images gallery. Télémesure › Images SSDV keeps the explanation and the packet import, and says in one line how many pictures there are, with Voir dans Images ›.

• IC-9700 on Windows: the missing USB driver, noticed and installed on a click. When the rig's CP2102N serial bridge (or its sound card) is plugged in without a working driver, Réglages › Poste et rotor says so under the port choice: « Un poste Icom (CP2102N) est branché mais Windows n'a pas son pilote. » Ouvrir la page du pilote (Silicon Labs, or Icom's page), Installer le pilote (the official driver downloaded from silabs.com, checked, installed with pnputil; Windows asks for permission), Choisir le zip téléchargé… if the direct download is refused, Rechercher à nouveau to read ports and sound cards again. Nothing is installed without a click; the driver does not ship with SatMe. Reminders: switch the rig on before plugging the cable in; Windows Update › Optional updates may offer it too; on the rig, CI-V USB Port « Unlink from [REMOTE] », the same speed as in SatMe, CI-V USB Echo Back OFF. Nothing changes on Linux and macOS. If silabs.com refuses the direct download, download the zip with your browser: Installer le pilote picks it up from Downloads by itself. The notice also shows what Windows sees (each Silicon Labs or Icom device, its status, its code).
• Orbites: a card for every SSTV and SSDV picture satellite — LAPAN-A2, ASRTU-1, HADES-SA, SEEDS II, TeikyoSat-4, WREN, SONATE-2, UmKA-1, VIZARD-meteo, Monitor-3, UTMN2, AHMAT-1, SAKHACUBE-CHOLBON, QMR-KWT 2, GALAPAGOS-UTE-SWSU, Geoscan-2, -4, -5 and 239Alferov now have their card (Orbites tab, Fiche card): country, operator, launch date, mission and a story, each fact taken from public sources (the operator, Gunter’s Space Page, IARU, SatNOGS…). A new Format line: « 3U CubeSat », « PocketQube 1P », « Microsatellite de 50 kg »…, filled in for SO-50, AO-27, AO-91, RS-44, FO-29, IO-117, AO-73, PO-101 and JO-97 too.
• DATV transmit: more safeguards and sources (DATV tab, Émission sub-tab). The level starts at 0 and goes back to 0 after every stop (garder le niveau après l'arrêt, unticked by default); ÉMETTRE stays greyed at 0, and until the callsign and locator are given (Réglages › Station; neither NOCALL nor AA00), the reason written under it. A click on the wide band spectrum sets the transmit frequency (un clic choisit la fréquence d'émission box) and says "slot that looks free / busy" — indicative only, from the ground station's spectrum. Only the page that started it keeps the transmission alive: closing it stops it; another tab or the phone does not keep it alive and closing them changes nothing. PTT / sequencer output (none by default): a serial port's RTS or DTR line, or an HTTP request to a network box; output active, delay, RF; RF off, delay, rest; Tester without RF. Simulation: everything runs, nothing is transmitted. Sources: a folder of videos looped, scrolling text in the overlay, a sound delay of −500 to +500 ms.
• SSTV: colour analysed and corrected, and an optional AI denoiser. In the viewer, 📊 Analyse says what is measured on the picture: colour cast (and the tuning error it amounts to), colour shifted against the picture (to a tenth of a pixel), levels, saturation, noise, mark. 🎨 Couleurs corrigées sets them right, nothing invented (a step whose measure is not clear is not applied, a picture already right comes out unchanged); Avant | Après compares. The default and the steps: SSTV › Réglages › Couleurs et IA. The picture as received is never changed; the finished version also goes to the sheets and, if you choose so, to your site.
• AI denoising (off out of the box): SCUNet (Apache-2.0 licence) on the processor, 2 to 3 s a picture. SSTV › Réglages › Couleurs et IA › Installer downloads it (about 170 MB, checksums checked). A picture through the AI is always marked « IA »: gallery, viewer, sheets, site.
• SSTV: automatic AI denoising, its settings, and the version sent to your site. Once the model is installed, SSTV › Réglages › Couleurs et IA offers Débruitage IA automatique (off out of the box): each picture received goes through the AI by itself, in the background, one at a time, never delaying the decoder or the auto-pilot; only when the noise reaches a threshold (5 by default, the σ of 📊 Analyse) so clean pictures are left alone. The AI's settings: strength (0 to 100 %, the denoised picture blended over the one before), order (before or after the colour), tiles and overlap, threads (processor only); Tester sur une image shows before | after with a line to slide, keeping nothing. In the viewer, each picture's IA box still wins (unticked, the picture stays without). In Réglages › Envoyer vers un site web, Images SSTV : la version envoyée — as received (the default), colour corrected, or AI (and colour); a picture whose AI version is not ready yet goes as received, then again, replaced, once it is. Your site receives retouche (couleurs or ia) to say so.
• Voice assistant (optional module, off by default, Settings › Modules): say "SatMe, next ISS pass" to the PC's microphone — next pass of a satellite or of your favourites, satellites in view, next AOS, autopilot, last SSTV picture, DATV, QO-100 beacon, rotator position, last QSO; and a few gestures: autopilot, SSTV or DATV reception, mute. Whisper writes the sentence on this PC (a small model, 75 to 485 MB, Install button in Settings › Assistant and home automation), the "Spoken translation" voice answers, a bubble shows it at the bottom right; the 🎙 button skips the word "SatMe". Nothing is sent anywhere.
• Home Assistant (optional module, off by default): the station's state published to your MQTT broker, the entities found by Home Assistant by themselves (next pass and AOS, satellites in view, autopilot, SSTV, DATV, beacon, rotator, last QSO); with Actions, switches and a "Commande SatMe" field. Alexa or Google Home take them up through Home Assistant. The MQTT password stays on this PC, never shown again.
• Publication web › Remote commands (two boxes, unticked by default): for an Alexa skill on your own site — the site never connects to the station, SatMe-PC sends it the answers and fetches the commands. See docs/assistant-domotique.md.
• Never any transmission by voice or remotely: PTT, CAT, DATV, SSTV, FT8, ADALM-PLUTO transmission and rotator moves are always refused ("do it on the screen"); only eight receive or sound actions exist.
• DATV: smooth playback, picture and sound together. Tick Lecture fluide (vidéo et son) under "Son sur ce PC" in the DATV tab: the received picture plays in the browser as a real video (25 frames per second, sound in sync, about one second behind) instead of JPEG pictures one by one with the sound apart. Received H.264 is passed as is; H.265 and MPEG-2 are re-encoded to H.264 by SatMe-PC. Mute or set the volume with the 🔊 button at the picture's bottom left; on this PC, the "Son sur ce PC" sound goes quiet meanwhile so it is not heard twice (level meter, subtitles, translation and recordings carry on). Also works through a SatMe-Node and from another machine (remote access with the password, HTTPS included). A browser that cannot play it, or a failure: the JPEG pictures, as before. In the demonstration, the demonstration test picture.
• DATV: QO-100 beacon watch — the Balises QO-100 card of the DATV tab (surveiller, unticked by default) follows the DATV beacon (10,491.500 MHz) on the ground station's spectrum and, when the receiver is on it, as it reaches you: lock, MER, holes in the stream PID by PID, picture decodable or not; and the narrow band beacons as the SDR hears them (level, offset in Hz). It says plainly "défaut à la source, pas chez vous" (fault at the source, not at your end) when the beacon goes off or its stream arrives damaged while your MER is good (only video and sound have holes, no transport or FEC error), and "chez vous" when it is the signal or the PC. An alert shows in any tab; a 24 h to 7 day history (a box every 5 min) and the list of changes. Optionally, contrôler l'image de la balise avec le MiniTiouner libre tunes it for 60 s every 30 min while nobody uses it, then puts your settings back.
• DATV: automatic scan, always a picture — the Balayage auto card (toujours une image, unticked by default) moves to another signal when the one you follow does not lock, is lost or its stream is damaged: your favourites ★ first, then the beacon, then the stations present on the ground station's spectrum (the most recently received and the strongest first); x seconds on each or until it drops, and back to the followed signal when it returns. Tuning by hand (Recevoir, a click on the spectrum) pauses the scan for 10 min; it never starts a stopped receiver. With the PC's MiniTiouner or a SatMe-Node's.
• Web publishing: QO-100 beacons — a new Balises QO-100 line under En direct (unticked by default) sends the beacons' state (ok, absent, stream damaged at the source, weak signal; the cause, since when, the beacon's MER) in direct as balises: as soon as a state changes, otherwise every 5 min.
• QO-100 narrow band transmit: helpers, all unticked by default (the cockpit's Émission sub-tab, Aides à l'émission card). Simulation: everything works (PTT, time-out, CW, memories) but nothing is transmitted, no device opened. Level guard: on the air, our signal heard stronger than the beacon lowers the gain (or the IC-9700's power), 6 dB above it cuts the transmission; never raised. Listen before talk: "fréquence occupée" when somebody is already there. Pluto gain cap per profile (home, portable). CW memories with {MOI}, {LUI}, {LOC}, {RST} and prosigns (Alt+1 to Alt+6), a keyboard keyer, voice memories recorded in the browser and sent under the PTT (released at their end), a transmit journal (duration, uplink, level against the beacon, why it ended; CSV). Nothing ever goes out without the operator's click.
• DATV transmit: presets — the band plan's usual settings (net 333 kS on 10 499.25, 125 / 250 / 333 / 500 kS, 1 MS on 10 494.75, DVB-S) and your own (Garder…). A preset only fills the form: never the gain, never while transmitting.
• Satellite operating: transmitting through low-orbit satellites (new module, Réglages › Modules, off by default). A card under Émission IC-9700 (Suivi tab): a preset per satellite (CTCSS tone auto / none / chosen, a lowest elevation below which PTT is refused, power applied on demand), Armer SO-50 (74.4 Hz for 2.5 s, then the tone put back), a QSO assistant (the pass, the suggested exchange, etiquette, Noter au carnet), 6 CW memories ({MOI}, {LUI}, {LOC}) sent as a tone through the rig's audio, 4 voice memories recorded from the page, and APRS through the satellite (position, status, message, path ARISS) with a beacon armed for one pass only. Every transmission starts from a click, through the IC-9700's PTT and all its guards; Esc stops everything.
• ISS beacon through a KISS radio: armed for one pass only. Ticked, it holds for the ISS pass under way (or within 30 min) and unticks itself at LOS; it is never kept from one start to the next any more.
• Web publishing: the station's hardware — a new Description du montage line under Réglages › Services en ligne › Envoyer vers un site web › En direct (unticked by default) sends your site the hardware of the Montage tab (dish, LNB, converters, MiniTiouner, SDR, rig, amplifier…) and the signal's paths, from the antenna to the receivers and from the transmitter to the antenna, so that it can draw your QO-100 chain (type montage; to a folder, montage.json). Names and characteristics only, never an address or a serial number; as soon as it changes, otherwise once an hour.
• DATV: the record of the station selected on the spectrum. The callsign written on the selected signal of the wide band spectrum (the one the receiver is tuned to) is looked up on QRZ.com: its record shows first, Station sélectionnée sur le spectre, even before the lock. With Réglages › Services en ligne › Envoyer vers un site web › En direct › Image DATV, the site also gets the station watched: callsign, name, town, locator, country, distance and bearing (never the QRZ photo, the e-mail address or the street).
• DATV through a SatMe-Node: reception resumes by itself after the node restarts (service restarted or Pi rebooted). SatMe-PC starts reception there again with the same settings and takes the stream up again; "node silent" clears as soon as the node answers. A stream silent for 20 s is reopened: it no longer stays stuck after a cut.
• Speech to text: 15 more languages can be translated — Danish, Swedish, Norwegian, Finnish, Estonian, Latvian, Lithuanian, Slovak, Hungarian, Romanian, Bulgarian, Slovenian, Greek, Turkish and Catalan, through English like the others. Tick them in Settings › Speech to text, then Install translation (about 65 to 150 MB per language).
• QO-100 beacons: a fairer verdict — « Weak signal: frames are lost at your end » no longer shows when no packet is lost: the receiver's FEC flag alone no longer counts (blocks must really be left uncorrected), and a few decoder errors on a stream received whole leave « picture fine ».
• Speech to text: Arabic and 11 more languages of QO-100's footprint can be translated — Arabic (the QARS beacon's video), Persian, Hebrew, Hindi, Urdu, Bengali, Azerbaijani, Albanian, Galician, Basque, Thai and Esperanto. Tick them in Settings › Speech to text, then Install translation (about 65 to 115 MB per language).
• My website: a picture is no longer lost while the site bans the address for a while — it stays in the send queue and goes once the ban is lifted, instead of being counted as refused.
• Globe: a seventh look, Bleu nuit (night blue) — sober, like the globe of a website's home page: night-blue space, a deep blue ocean, green land lit by the Sun, the night and a soft twilight band worked out point by point, a fine coastline, a blue atmosphere glow; your station an orange dot, the satellite a bright light with its cyan footprint. Chosen wherever the look is: Orbites (the looks' bar, right of Carte ancienne), Suivi › Globe (the list at the globe's top right), Sked › Réglages du globe › Rendu and the Journal's globe; the journal's and the skeds' pictures, GIFs and videos follow it.
• DATV: the LNB supply and the reception survive a restart — the 13 V / 18 V chosen is kept (the auto scan, the beacons' watch and a restart no longer cut the LNB), and a reception running when SatMe-PC stops is taken up by itself at launch (not if it was stopped by hand).
• Orbits › Dashboard: the globe of your choice in each theme — a « Globe » menu beside « Theme » (the theme's own look, or any of the tab's, Bleu nuit included), kept for each theme, and a « Bleu nuit » theme.
• Globes: a « Transparency » slider — from opaque to very transparent: the orbits, satellites and stars behind the Earth show through. In Orbits (the settings bar, and the dashboard's Information menu) and in the Sked's globe settings; one for every globe, kept in the browser.
• DATV › Auto scan: a « rotate » mode — x seconds on each signal in turn (favourites, beacon, stations on the spectrum, the followed one included), even while all is well; a signal without a picture is left sooner. « x seconds on each » only applied as a fallback, when the followed signal drops.
• No more reloading the page after an update — a SatMe-PC page left open sees that SatMe-PC was updated or restarted and reloads by itself (never while transmitting, nor while something is being typed: a banner offers it then).
• DATV › Auto scan: the switch shows, with a countdown — over the received picture, a chip « ↻ station · 23 s → next » while the scan runs (the countdown in rotate mode, and in x seconds on each while on a fallback); on each switch, a banner « Bascule : IZ0ZWS → IK5EHI » with the reason for 4 s, in full screen too. The Balayage auto card shows the same countdown. With Mon site web › En direct › Image DATV, your site gets the station, the countdown and the last switch (datv.balayage: names and frequencies only) to show them the same way.
• Globes: « Transparency » at 0 is truly opaque — the names of satellites behind the Earth no longer show on top of it; they come back as the transparency is raised.
• Your site: the auto-pilot's banner gives the campaign's real end — « SSTV until 30 Oct » from its dates, even when the name taken from an announcement still said « 27 to 29 ».
• The auto-pilot's banner can be moved — it may hide buttons (the agenda): drag it by « 🤖 Auto-pilote », it keeps its place in this browser; a double click puts it back under the header.
• DATV: a picture « Qualité » per browser, for tablets. Above the MER in the DATV tab: Qualité Source (the default, the picture as received), 720p, 480p, 360p or Auto, kept for this browser only — a tablet can stay on 480p while the station PC keeps the source. The smaller sizes are re-encoded by SatMe-PC, smaller and lighter (H.264 from 2.5 Mbit/s down to 600 kbit/s with Lecture fluide, lighter JPEG pictures otherwise), once for all the browsers asking the same one; two re-encoded sizes at most at once to spare the processor (a third one asked gets the nearest, and the line says so), stopped 10 s after the last viewer. Auto goes down a step when the browser drops pictures, stalls or falls behind, and back up after a calm while (« Auto · 480p »). Beside it: the received rate in kbit/s and the dropped pictures, to compare.

• Web publishing: SatMe-PC pushes to an outside web site, whatever it is (an optional module, off by default, which no profile switches on; Réglages › Modules). While it is off nothing goes out (no queue, no test, no live data) and no 🌐 button shows. Ticked, Réglages › Services en ligne › Envoyer vers un site web: SatMe-PC sends over HTTPS what you choose — SSTV pictures, planches, reports, contacts, the journal's videos — to an address of your site (with {type}, or one address for everything), an optional token; your site receives them as it likes (PHP, WordPress, a small Python server…). Tester (required: ready only after a test that passes), then each kind Sur clic (the default), Automatique or Jamais. The format is a documented, versioned API (X-SatMe-… headers, multipart/form-data with a JSON card, one id per delivery so nothing is published twice), with ready-to-use receivers in PHP and Python and a page showing what was received: see docs/publication-web.md. A refused token stops everything until the next test; a refused kind shows « refusé (403) » in the history.
• Web publishing to a folder: with no server, SatMe-PC writes each item into a folder of this PC (type/year/id.ext and its .json card, an index.json, an Atom feed flux.xml, never leaving half a file), for a static site or a sync tool you already have (Nextcloud, Syncthing, an rsync or FTP mirror).
• Windows installer: an update no longer deletes any of your files. satme-pc-windows.msi emptied the whole program folder when replacing the old version, a donnees folder put beside it (portable mode) included. It now removes only its own files. Before installing this one over 2026.10.33 or older, copy a donnees folder kept in the program folder elsewhere: the old version still empties it one last time as it goes.
• Installed by the MSI, SatMe-PC keeps its data in %APPDATA%\SatMe, never in the program folder: a donnees folder found there is copied at start to %APPDATA%\SatMe (or %APPDATA%\SatMe-portable-<date> when that is in use), checked, then used; the original is kept and a window says where your data is. Réglages › Démarrage refuses a data folder inside the program folder. Portable mode stays the ZIP's (USB stick).
• Web publishing › En direct (live, optional, each part ticked on its own, nothing by default) — Auto-pilot (a campaign's next pass, the reception under way, the next picture, the last picture received; during a pass, the picture arriving every 5 s), QO-100 spectrum (the narrow band as the SDR sees it, one line a second) and DATV picture (a small picture and the MER while the receiver is locked). The site never connects to the station; only names, times and measurements, never an address, a code or a key. No queue: when the site does not answer, SatMe-PC waits and tries again; « Effacer le direct » removes it at once. To a folder: direct/direct.json and the pictures. A station that already published to its site keeps the module, and its address becomes …/api/publication/{type}.
• SSTV: the satellite followed, reminded in an inset beside the live picture: its name, the auto-pilot's 🤖, the SSTV mode and downlink frequency, the Doppler-corrected receive frequency; the pass's sky (AOS, LOS, highest point, the satellite now), a small globe (ground track, footprint); AOS, TCA and LOS in local time and UTC, max elevation, position now, range, time left — or the next pass. ▾ folds it, ✕ hides it (back from SSTV › Réglages › Affichage); stacked under the picture on a phone.
• Web publishing: planches say everything about their series — the satellite, the event or the auto-pilot's campaign, the first and last picture's dates, slides received out of those expected and the ones missing, the best picture of each slide, the passes that brought pictures (AOS, LOS, max elevation, number of pictures, 🤖 auto-pilot) with each one's journal video, and the link to their report. An SSTV picture and a journal video say their pass and whether the auto-pilot received them (and for which campaign). More optional fields in the JSON card, described in docs/publication-web.md: a site that does not know them ignores them.
• Web publishing › Favourite satellites (a box under En direct, unticked by default): the list of the satellites marked ★ goes to your site as soon as it changes, otherwise at most once an hour (type favoris; to a folder, favoris.json), for instance for a home page to feature them. A site that does not know this type is left alone until the next day, without an error message.
• French wording: « pylône » instead of « mât » (the rotor's mast) throughout the French interface and documentation.
• SSTV: the number of the ARISS series 33 slides is read (« SLIDE 6/12 », yellow and thin, often cut by the picture's bottom or moved up when the picture began late): the ISS pictures of 3 and 4 October are sorted in order, 31 of 34 numbered (an unreadable copy takes the number of its slide's other copies). The series' number (« СЕРИЯ 33 ») is read too: a picture of another series no longer counts in the « ARISS SSTV Series 34 » event.
• Planche › Relancer l'analyse: only the event's pictures (the default when the sheet has one) or all the pictures, chosen beside the button.
• Web publishing › Diplômes (a box under En direct, unticked by default): the awards followed in Agenda › Diplômes go to your site as soon as they change, otherwise once a day (type diplomes; to a folder, diplomes.json) — name, issuer, your progress (« 37/100 squares »), where each stands (in progress, reachable, asked for, received, event to come), dates and the link to the rules; never the contacts counted, the pictures' names, the notes or your details. On an award whose picture is attached, Envoyer le diplôme reçu sends that picture (or PDF) to your site, on that click only (type diplome-image).
• French wording: « locator » instead of « carré » (grid square) throughout the French interface and documentation: the Locators tab, « locators contactés », « En cours : 37/100 locators », « nouveau locator » (FT8, APRS, log), the Locator column; « sous-carré » becomes « locator à 6 caractères » and Maidenhead fields « locators à 2 lettres ». The English text likewise says « locator » for « grid square ».
• Journal: the video follows the preview exactly. The speeds (During the pass, Outside the passes, Picture or contact), the ×1/×2/×4 « Speed » under the preview, the margins, the silences skipped and the globe's camera (Chase, From the station, Seen from the satellite, Overview) go into the video as they are: the preview now plays on the video's own timeline. Make tells the video's length before it is made. The sound only plays where the time runs in real time (×1), here as in the video: never sped up nor slowed down. The « Accelerated replay » box becomes « Skip the silences » (what has no QSO, no picture and no sound heard plays fast and silent; the rest in real time with its sound, or at the Picture or contact speed with no recording — never again a silent pass played at ×1), with its Silences speed under the other speeds and its stretches hatched on the timeline; the settings already kept still apply.
• Frequencies (Doppler): every live transmitter, with its frequency, whatever its mode (« SSDV », « GENESIS FSK »…), and the rig's mode for it: slow FSK (under 1200 bit/s), SSDV and SO-127's « GENESIS FSK » put the IC-9700 in USB-D (no longer FM). Autre fréquence… at the end of the list: a downlink in MHz, an optional uplink, the rig's mode (USB, USB-D, LSB, FM, FM-D, CW), Doppler-corrected like the others and kept for that satellite (« Oublier » removes it). On the phone, the PC page does the same, and the list no longer shifts the choice when an inactive transmitter comes first.
• SO-127 (HADES-SA) SSDV: *Télémesure › SSDV en BLU. SO-127's two-tone FSK (800 bit/s, 1600 Hz shift, or 200 bit/s, 1125 Hz) decoded from USB audio — the rig's sound card (IC-9700 in USB-D) or the SDR receiver: the tones searched across the audio band, the GENESIS frames (sync 0xBF35, CRC-16, descrambler), and the SSDV packets, which join the pictures pass after pass. **Capturer les bits* keeps each pass's bits; Relire decodes afterwards a recording of the Son tab or a WAV from another program; Essai runs a made-up test chart. Receive only. Checked on made-up signals: to be confirmed on a real pass.
• SSDV over an FM repeater's AFSK 1200 (IO-86 / LAPAN-A2): packets sent with ssdv2sat, bare or in AX.25, whole or shorter, are taken from the card's APRS decoder frames and join the SSDV pictures.
• Geoscan satellites' pictures (Geoscan-2/4/5, 239Alferov): their GFSK 9600 frames (sync 0x930B51DE, PN9, CRC-16) are read by the packet decoder, and their JPEG chunks rebuild the picture in Télémesure › Images SSDV as they come. Checked on made-up signals only.
• SSDV pictures in the SSTV tab (SSTV › Images): those of the last three days, under way or complete, with their packets received and missing and the passes that brought them.
• Auto-pilot: SSDV campaigns — Décodeur SSDV en BLU (SO-127) in a campaign's chain (ticked by itself for a satellite sending that way); a frequency of its own may be USB or USB-D. The pass's report says how many packets came.
• Web publishing: SSDV pictures (type ssdv-image, Sur clic by default): the 🌐 under each picture, with satellite, NORAD number, first and last packet, packets received / expected and missing, the passes that brought some (and the auto-pilot); a picture already sent goes again by itself when more packets come, under the same key. To a folder too.
• Web publishing › FT8/FT4 (a box under En direct, unticked by default): each FT8 (15 s) or FT4 (7.5 s) slot, once decoded, goes to your site — the satellite of the pass under way (or the band), and for each message heard its audio frequency, report, text, the callsign and locator it gives, CQ or for you (60 at most), with a small strip of the waterfall to draw the spectrogram (type direct-ft8). A whole journal pass with its messages goes on 🌐 in the FT8 tab (card « Passages FT8/FT4 sur le site »), or by itself when the pass ends in Automatique (type ft8-passage, Sur clic by default). Only messages heard over the air.
• Journal: a nicer closing summary, pictures at their own size. The video (and the identical preview) ends on a summary card: satellite, date, station, the pass's or session's figures (duration, max elevation, pictures, contacts, stations heard, locators, FT8/FT4 decodes, distances), the track in the sky and the pictures in a grid, thin-framed and captioned (time, mode, slide number). SSTV pictures are no longer blown up full screen (blurred): never more than 1.5× their size, never stretched. New Summary length slider (Make, 7 s by default), counted in the video's announced length. In 16:9 as in 9:16.
• Journal: the sound is back, sped up to ×4. Since the preview followed the video, a recorded pass stayed silent except around logged contacts (and whenever Speed went above ×1). New Sped-up sound box (Make, ticked by default): where there is a recording, its sound plays sped up to ×4 with its pitch kept, in the preview as in the video; a recorded pass therefore runs at ×4 at most (×20 elsewhere), the announced length includes it. Faster than ×4: silent. Skip the silences keeps its paces. On the timeline: green line = real time, light green = sped-up sound.
• Journal › Sped-up sound: a pass is held to ×4 only where something is heard in the recording (with 2 s around); elsewhere the chosen paces apply, silent.
• Journal: « Outside the pass » before the AOS and after the LOS, even for a single pass. The pass is AOS to LOS (During the pass, ×1: real time with the normal sound); the margins before and after, and the time between two passes in Continuous, run at Outside the pass, reached quickly (×20 to ×1000 in about a hundred seconds) while the slowing down stays gentle inside the pass, nothing skipped there. A few minutes of margin no longer lengthen the video. Sped-up sound holds to ×4 only between the AOS and the LOS. Options: the Outside the pass slider always shown, the speeds named for where they apply, and a Sound block (With the recording's sound, Sped-up sound, Skip the silences and its speed) — Make keeps only the files. On the phone's page too.
• The manual as a PDF: this guide laid out for printing (cover, contents with page numbers, the chapter at the top of each page, the screenshots), in French and English, attached to every release on GitHub (SatMe-manuel-fr.pdf, SatMe-manuel-en.pdf). ⤓ Télécharger le manuel (PDF) at the top of the built-in manual (F1). The guide is up to date with all of the above: web publishing, SSDV, Autre fréquence…, Journal (speeds, sped-up sound, closing summary), SSTV series 33 and 34, Windows data.

• SSTV › countdown to the next picture (under the live picture, and in the Auto-pilot card): a ring and « Prochaine image dans 1:24 », from the campaign's timetable or estimated on the pass's pictures, put right on each one; the picture under way's progress, « en retard », « en attente », « fin du passage » at LOS; 🔔 a beep 5 s before (off by default).
• SSTV: a picture is no longer cut in two when its sync is lost in the middle (a fade, a jump of the sound — UmKA-1 on 27/10: the top in one partial picture, the bottom in another): the decoder finds it again and goes on with the same picture at the right row, the lost rows marked. ⧉ Réunir (viewer, Journal, the auto-pilot's history; on its own at the end of an auto-pilot pass) puts two partial pictures from before back together from their sound; the partial ones are kept, ↶ Séparer brings them back.
• Réglages › Services en ligne › Site web: SatMe-PC publishes on your amateur radio web site (SatMe's « site » module, the one behind f4ioz.fr) the SSTV pictures and planches by itself, the reports, contacts and journal videos at a click (🌐 in the SSTV viewer, the log, the Planche page and the journal's editor) — each kind Automatique, Sur clic or Jamais. Address, token (kept on this PC, never shown again), Tester la connexion; a queue on disk tries again while the site does not answer. In the demonstration: only to a site on this machine.
• 🤖 Auto-pilot in the lists: a pass an SSTV campaign will receive carries a small 🤖 next to its time — Station's passes, the followed satellite and its next passes, the header, Agenda, and in Orbites (satellite list, next passes, dashboard). The tooltip names the campaign and the status; it pulses while receiving and is dimmed when the pass will be lost (with the reason) or the auto-pilot is off.
• FT8 / FT4 transmit (FT8/FT4 tab, Émission FT8/FT4 card): through the IC-9700 SatMe already keys, terrestrial or through a linear transponder (RS-44, QO-100) with the satellite's Doppler and offset. Double-click a line to answer, 📣 Appeler CQ, six editable messages Tx1–Tx6, automatic sequence up to RR73/73, TX frequency marked on the waterfall (Shift + click), never on the called station's own. No unattended QSO: a QSO only starts from your action, an attendance watchdog (3 min) stops transmitting, ■ Arrêter l'émission and Esc always there. Refused when the clock drifts (±0.5 s in FT4). Mode données (USB-D), on by default: while transmitting is armed SatMe puts the IC-9700 in USB-D / LSB-D (both bands in satellite mode, the Doppler loop keeps it), never during PTT, and puts the previous mode back when it stops; on the rig, DATA MOD = USB. QSO over: Noter le QSO prefills the log (satellite, SAT mode). In the demo: simulated transmit, made-up stations answering.
• FT8/FT4 tab on one page: the waterfall (its height follows the window), the decoded lines and « Qui appeler maintenant » on the left; the Émission FT8/FT4 card and the radar on the right, no scrolling (1920×1080, 1500×900, 1366×768). Tx1–Tx6 dense as in WSJT-X, the buttons on one row that stays in sight, audio level and data mode under Réglages. On a phone, the cards stack.
• Sked › Vidéo › Globe animé (comme à l'écran) (animated globe): on the globe, the video is filmed by the browser from the page's real globe — relief, clouds, landmarks, animated scenery, the look and camera chosen — with both skies and the usual band, in 16:9 (1920×1080 or 1280×720) or 9:16 (1080×1920). Keep the tab visible while it records (≈ 30 s); SatMe-PC makes it an MP4, or the raw video can be downloaded.
• Journal › videos, pictures and GIFs: real flags: the FT4 / FT8 decodes panel and the globe's capitals in « nom et drapeau » (name and flag) or « drapeau » now show the very flags of the page (England, Scotland and Wales included) instead of the codes « DE », « SCT », « CA ».
• FT8 / FT4 receive: « R-12 » now shows its R (it read « -12 »), reports on two digits (« -07 »), and free text is decoded.
• Journal › FT4 / FT8 decodes on the replay: when a pass (or a session) has some, Options › Décodages FT4/FT8 shows the messages received up to the replay's time in a panel laid over the view — UTC time, dB, message, flag; CQs in green, your callsign in red, your contacts in pink. Drag it, its corner for its size (the text follows), Visibilité (visibility) 0–100 %, newest at the bottom or the top; kept with the pass, and the video shows it the same (16:9 and 9:16). The FT8 tab's decodes are now kept with each pass; Redécoder depuis l'enregistrement (re-decode from the recording) for a recorded pass.
• Orbites full screen: the logo and "SatMe" top left (bottom left in Classique radioamateur).
• Agenda › Diplômes: the awards to claim and where you stand — each session's ARISS SSTV award (its page, the ARISS calendar, your campaigns) and the certificates announced by AMSAT, AMSAT-UK, AMSAT-F, matched with the pictures received during the event (best marked first); the standing awards (VUCC, DXCC, WAS satellite, AMSAT…) counted from the log (« 37/100 grids »). « Obtainable — ask before 30/10 », mark asked / received, attach the certificate received; a notice when an award becomes obtainable or its deadline nears. Add from a flyer… (a picture read by tesseract or pasted text) and Prepare the request: everything the form asks, to copy, with the pictures' pack. Nothing is sent; filling in forms automatically will come later, with your consent.
• DATV › Pointage (button at the top of the tab, or pc?pointage=1 on the phone): the MER very large, the D margin, the trend (▲ better / ▼ worse than 5 s ago), the best (reset), the level, a 2-minute curve and a tone whose pitch follows the MER; « DÉCROCHÉ depuis… » in red if the lock goes. Reminder: the beacon alone is the reference, one touch-up at a time.
• DATV › Quality › History: MER, D margin and level over 10 min to 24 h, the time unlocked in red, marks (station changed, stop, LO calibrated, Marquer une retouche).
• Signal level estimated from the MiniTiouner's AGCs (≈ dBm, MiniTioune / Portsdown scale after BATC's measurements): good from −70 to −35, too weak or too strong said plainly.
• Calage auto sur la balise (Reception card, unticked by default): the LNB's real LO and its drift measured on the beacon, always shown; ticked, taken at the next tuning.
• Mon spectre — SDR on the same LNB (unticked by default): the SDR tab's receiver (RTL-SDR, Pluto, bladeRF, SatMe-Node) on a splitter sweeps the wide band, on the ground station's scale; a click tunes the MiniTiouner. Warns when the beacon is not in it.
• LongMynd settings and decoding: search width (-S), wait without packets (-r), passed to the SatMe-Node; tolerant decoding for damaged streams.
• DATV › Subtitles › Spoken translation (off by default): each received over's translation said by the voice-to-text synthetic voice, with its own voice, volume and the original sound lowered while it speaks (adjustable). Never over itself: only the latest over waits, nothing more than 20 s late. It plays where the DATV sound plays (this PC's speaker, the browser listening), through a SatMe-Node too; with no voice installed, the card leads to the installation.
• Subtitle display: width, number of lines (1 to 4), line length (≈ words per cue), size (auto or fixed), duration, and More text (4 lines, 90 % wide, the previous cues kept above). Instant preview, set per browser, nothing is ever cut off.
• Summary of the station received (and the previous ones): callsigns heard, read in the picture or in the service name, reports (5/9, MER, margin), locators, gear named, frequencies, key sentences, in your language. Made on the PC without Internet; Copy and Log the QSO (fills the log without saving).
• Sked › Carte / Globe: the common window also replayed on the Orbites tab's globe, with all its looks (cartoon, realistic, hologram…) and settings (camera, details, cities, names, landmarks, their size and families) under Réglages du globe. Both stations named, the satellite's track, the part you both see in green, its footprint; the slider and ▶ drive it. Drag to turn, wheel to zoom, double-click to frame it again. The choice is kept; the map stays the default.
• Sked › Video on the globe: in Globe mode, Vidéo makes the MP4 on the globe, with the look (all six), camera and settings chosen (cities, names, details, landmarks, Traces): both stations named (you in amber with callsign · locator, the other with its locator), the satellite and its footprint, the track with the common window in green, the line to each station that sees it, both skies and a band (satellite, date and UTC times, max elevations, « vous le voyez tous deux », SatMe). 16:9 or 9:16 (phone upright) beside the button, for the map too.
• Télémesure › Images SSDV: a picture sent again over several passes (same callsign, same number, within 3 days) is completed with the new packets; "N/M packets, X %", a strip coloured by pass (grey = missing) and the list of passes. Packets are kept in telemesure/ssdv/paquets (a picture under way survives a restart, duplicates dropped); once complete it joins the gallery. Under way: ⤓ PNG / JPEG or Abandonner. Importer des paquets…: raw packets, KISS or the frame log of a missed pass. In the demo: two pictures made over two passes.
• SDR › satellite scale between the spectrum and the waterfall: every known downlink at the frequency heard here (Doppler and correction included), green above the horizon, white rising within 5 min, grey below; linear transponders as bands following the Doppler. Click a name: follow that transmitter; inside a band: tune there; elsewhere: a fixed frequency. Wheel on the passband: fine tuning (Alt: faster); Ctrl + wheel on a satellite: its manual correction. Tooltip: mode, Doppler, el/az, AOS/LOS.
• Orbites › Passage › Vue du satellite (seen from the satellite; a new camera, also in the Sked's Réglages du globe and in the Journal): the Earth seen from above, straight below the satellite — its footprint (the radio horizon), your station and the sked's other station, the log's contacts when shown, the day / night line, its ground track ahead and behind, the cities and landmarks. Beside it: altitude, footprint radius, day or night below it, « your station: in view, X km from the edge ». Drag to look around, back by itself or on a double-click; the Hauteur or the wheel bring it nearer, down to the satellite. In Vitrine, the globe goes there 30 s every 90 s.
• Converters and transverters (Réglages › Poste et rotor): a table of bands — RF from… to…, LO, inverted, and in front of what (SDR dongle, CAT receive, CAT transmit); the first matching line wins. QO-100 presets (9750 LNB, down-converter to 2 m / 70 cm, 2400 uplink from 432 or 144) and 28 MHz IF transverters; the previous setting kept at the top. With no line nothing is sent to the rig and the status bar says so in yellow; hovering a frequency shows the IF sent.
• Calibrer la clé SDR…: on a QO-100 beacon, a GSM base station's FCCH tone or a known frequency, SatMe finds the peak, gives the error in ppm (saved in one click) and, behind an LNB, its real oscillator. Aligner… (Suivi, Fréquences (Doppler) card): the downlink on the beacon, then the uplink with your own dots (you key the transmitter yourself), kept per satellite.
• Agenda › Activités à venir › Activer l'auto-pilote: on each SSTV activity, one click, a confirmation (satellite, frequency, mode, period, useful passes, default chain; receive only, nothing is transmitted) and the campaign is created and switched on, the auto-pilot turned on if it was off. The card then says "Auto-pilote actif ✓" with the next pass to be received, Suspendre (pause) and Voir la campagne; if the activity's dates change, the campaign follows (unless its period was edited by hand). A satellite named without its number ("UMKA-1", "ERMINAZ-2U becomes AO-129") is looked up in the catalogue, otherwise picked once in the confirmation and remembered.
• Orbites › Traces (slider in the options bar, and in Sked › Réglages du globe): the satellites' tracks from discreet to very marked — thicker, more opaque, outlined (dark on the cartoon, realistic and old-map looks, light on the dark ones). Globe (orbits, ground track seen from the satellite), 2D map, the pass's sky, the Sked's globe and map; ahead still vivid, behind paler. Stronger than before by default; kept in this browser.
• Orbites › 📺 ISS en direct: the ISS's live video (NASA, via YouTube; needs the Internet) in a movable window, with its position worked out by SatMe (sea or country below, altitude, speed, day or night under it) and Voir sur le globe (the Vue du satellite beside the real one). automatic NASA source (today's live looked up by SatMe-PC), ⚙ for another one; as a corner tile on the Tableau (Vitrine).
• Orbites › Tableau: the satellites' cards (photo and facts, one after another) are no longer cut off, in every theme and at every screen size: a corner too full is made a little smaller, the photo is shown whole (never cropped), the story goes under the photo; the card is left out only as a last resort. The Orbites tab's card shows its photo whole too.
• Activer l'auto-pilote (Agenda › Activités à venir): the campaign starts from the rotator's lowest elevation (Réglages › Poste et rotor) or the station's minimum elevation when higher; Élévation minimale editable in the confirmation, the list of passes follows.
• DATV › Émission › Créneaux (slots): the band plan's channels at this rate, green free or red busy on the ground station's spectrum (with the callsign), hatched near the beacon; a click on a free one sets the transmit frequency. The same marks under the wide band spectrum, our signal marked « TX · callsign », and the ÉMETTRE confirmation says whether the channel is free.
• Signal summary: standard, MODCOD, frequency, rate, the MER receivers need, codec, picture size and frame rate, sound and the video's share of the stream.
• Tester l'encodeur (encoder test): a few seconds coded by ffmpeg to nothing (H.264, H.265 and the hardware encoders present), kept per rate and MODCOD, with a recommendation and Passer en H.265 / H.264. Nothing is transmitted.
• « Horloge en direct » source (live clock): dial, UTC time, callsign and locator drawn each second, a beep each second.
• Gain ramp ▼ / ■ / ▲ while transmitting and power calibrated per rate (remembered when the MiniTiouner loop sees us 1 to 6 dB under the beacon; offered, never applied by itself).
• Orbites › Tableau › Vitrine: the globe stands beside the card (above it on a portrait screen) instead of hidden behind it. Card size (small, medium, large) and its side (left, right) in Informations ▾; the text shrinks to fit, never cut. No more "come and listen!" by default: the cards only say when the satellite passes ("passes over us at 15:29"); the invitation comes back with Réception sur le stand (a receiver on the stand).
• Tableau: move the globe (every look): Informations ▾ › Le globe › Le déplacer then drag (or Shift + drag, or two fingers), the wheel or the fingers' spread for its size, double-click or Remettre le globe à sa place to put it back. Kept per look; the Orbites tab is unchanged.

• QO-100, narrow-band transmitting (cockpit › Émission sub-tab): the ADALM-PLUTO straight on 2.4 GHz in SSB (the browser's microphone, or a sound card of the PC for FT8 from WSJT-X), in CW (text or key) — its oscillator parked below the transponder, its frequency correction typed or measured on its own downlink, the uplink tied to the cockpit, the AMSAT-DL band plan applied per mode. PTT held (or latched for FT8) with a 2 s watchdog and a time-out, dummy load (−40 dB) at every start, a gain cap, cut at once when LEILA is heard, "your signal vs the beacon" while transmitting.
• Fixed / Portable uplink profiles: chain, antenna (80 cm dish + POTY, 35 cm dish, 20-turn helix), amplifier and cable → estimated EIRP and suggested power under the beacon (order of magnitude), and Voir au Montage (2.4 GHz helix and 35 cm dish added to the catalogue).
• IC-9700 + up-converter on QO-100: PTT refused on a beacon, released when LEILA is heard, level compared with the beacon, and the converter's LO measured on its own downlink.
• Antenna polarisation (new module): an ESP32 box on USB drives a WiMo switch — V, H, right-hand circular, left-hand circular. Réglages › Poste et rotor › Polarisation d'antenne: the port, Tester la liaison (test the link), what is fitted on UHF and VHF (WiMo or an H/V relay), right and left swapped if the wiring wants it. Nothing is opened until a port is chosen; the firmware and the drawing are in materiel/esp32-polarisation.
• Suivi › Polarisation: the V / H / D / G buttons, the real state (including « manuel (sélecteur) » and « bloqué : émission »), and each satellite's polarisation at AOS (fixed, or the best known). The front panel selector has the last word, and never a switch on the antenna that transmits.
• Sonder H/V (probe H/V): in AUTO, the receiving antenna tries H then V, measured by the rig's S-meter or the SDR, and keeps the best (hysteresis). Every measurement is kept: per satellite and elevation, SatMe learns the best polarisation and starts the next pass with it.
• Virtual ESP32: the same rules without the box, its front panel on screen and a simulated pass, to try everything before soldering.
• Demonstration: satme --demo. A made-up station (callsign QF4DMO, every callsign in the Q series, nobody's) with an invented but believable log, pass journal and SSTV pictures, always dated in the last few days; virtual rig, rotator, SDR, aircraft, ships and an SSTV test card. Nothing real is opened, nothing transmits, nothing is sent under the made-up callsign; a « DÉMO — données fictives » band and its Remettre à neuf button on every page. A folder of its own (~/.satme-demo), works offline.
• On a VM or a Raspberry Pi: the satme-demo.tar.gz archive and its installe-demo.sh (dry run with --sec) install the satme-demo service (port 8090, open to the network with a password).
• Journal, 16:9 video: the caption at the bottom now takes 19 % of the picture (28 % at most with the largest texts, against nearly half before): three columns — the satellite, date and time, pointing on the left; AOS, RX, AOS · TCA · LOS and S-meter in the middle; the mark, the pass and pictures received, the station on the right. The view (sky, map, globe) gets the room, and the Fabriquer preview shows exactly the same frame.
• DATV, TV-style subtitles: each over cut into cues of two lines at most (by sentence), each shown for a time proportional to its length, the translation under it; nothing cut off any more — the font fits the picture (full screen too) until everything shows, with a readable minimum.
• DATV, callsigns read in the picture: they follow the station — put away on a new frequency or service and on a lost lock, and after 5 min without being read again; "seen just now" or "seen 3 min ago", older ones apart under Vus avant.
• DATV, text lists latest on top: subtitled and translated overs, the wide-band chat, the station card's and transmitted stream's chat — no more scrolling, the history stays below.
• DATV, steadier reception: Essayer aussi other symbol rates (LongMynd tries them in turn, longer for low rates); automatic restart of LongMynd when it stops by itself mid-reception, and of the decoder when the picture freezes while the stream flows; the margin is called Marge (D) as on Ryde.

• Journal: one editor, for one pass as for several. A session groups passes; an opened pass is a session of one pass. The same preview, the same tabs (Moments, Options, Fabriquer, Ajouter), the same settings, the same files. The sky and the map show the passes one after the other, the globe all together. 🌍 Plusieurs passages at the top of a pass, Ouvrir seul (open alone) from several.
• Screen 16:9 or phone 9:16 format: the frame is drawn over the preview (Fabriquer); the SSTV picture and the overlays are placed with the mouse or a finger, and the video, the GIF and the picture keep them in the same place.
• Start before the AOS, end after the LOS (0 to 30 min): you see the satellite coming, on the page as in the files.
• Two zooms (from afar outside the passes, near in a pass), the camera eases from one to the other; more satellites (favourites, their footprints as an option); the replay slows down as a pass or a picture comes near.
• The preview is the file: the page plays at the video's speeds (×20 in a pass, real time with the sound where a contact is heard; speed ×1 to hear the whole pass) and shows what is ticked for the video (RX, S-meter, the contact's record, opening card, next pass's card, mosaic).
• Exports of one pass or several: MP4 video with the contacts' sound, animated GIF, picture of the moment, WAV sound (end to end), the passes' files in a ZIP.
• Orbites always at the present time: opening the tab or the dashboard is at ×1, never paused nor on a replayed pass. The Passage view follows the pass under way live, else the next one with its countdown (▶ Rejouer en accéléré is a click away).
• ⛶ Tableau: Orbites full screen, six looks — Dessin animé (the globe turns by itself), Classique radioamateur (flat map, grey line), Nuit, Rétro, Pédagogique (bubbles coming one at a time, cards, "did you know?") and Vitrine for a stand or a club fair (big cards turning by themselves: "the ISS passes over us in 12 min — come and listen!", a satellite's photo, amateur radio in four lines, the club and its link as a QR code). Panels as you choose: time, next passes, chosen satellite, station, sunrise and sunset, the Moon, space weather, ticker.
• Satellite cards with a real photo (under Orbites' list, a dashboard panel): country, launch, mission, orbit, a story, frequencies, Wikipedia summary; a free photo (author and licence shown) asked once from Wikimedia Commons then kept, a drawing without the Internet.
• Nearly 250 landmarks, drawn by family: none / main / all, Types ▾ and Size (small to very big).
• Suivi your way (mouse or finger): panels fold, handles widen the columns and make the sky / map / globe bigger, Fréquences compact, ⊞ Disposition.
• Modules (Réglages › Modules): tick what interests you — QO-100, DATV, SSTV, SDR, FT8, APRS, METEOR, planes, ships… — or pick a profile. A module unticked leaves the menu, its settings and the status bar. On updating, everything stays ticked.
• New version: its window opens by itself, once per version. Portable shows in the header when SatMe-PC runs from its donnees folder. The SSTV auto-pilot banner counts the AOS and LOS down every second.

• Knob relay: the USB volume knob plugged into another PC tunes your station from afar. On that PC, start SatMe-PC, then Settings › Interfaces › USB knob › Relay to another station (also tick « Tune with the knob »): the station's address (https://… behind nginx, or http://192.168.…:8090) and its remote access password, used once and never kept. Each step is applied by the station with its own knob settings (step, target, learned keys).
• Knob on Windows: the volume keys (the USB knob among them) are read on Windows too, and can be captured so the PC's volume no longer moves.
• Portable SatMe-PC: a donnees folder beside the program (beside SatMe-PC.exe in the Windows zip, or bin and lib on Linux) keeps all the settings and files; nothing is written elsewhere on the PC. Ideal on a USB stick.
• New Orbites tab (Sky workspace): the Earth in 3D with your favourite satellites (or those ticked in All) going round on their orbits, their footprint on the ground and a line to the station when they are up. Six looks: Realistic, Cartoon, Hologram, Dotted globe, Retro radar, Old map. Time can run faster (×1 to ×1200).
• 2D map: the same satellites flat, their footprints, the ground track past and to come, day and night.
• Pass: the passes of the next 36 hours; ▶ Play the pass animates it fast, with the countdown to AOS, the culmination, LOS, the station's sky, elevation, azimuth, distance and Doppler. Three cameras (Chase, From the station, Overview) and an adjustable height (or the wheel) to see more of the Earth.
• Suivi tab: a Globe button beside Sky and Map shows the satellite followed, its orbit and footprint, the favourites around.
• Cartoon is the default look. The satellite chosen stands out: a ring turning round it, its name marked with a ★, a thick orbit, a clearer footprint; the others stay in the background.
• Details (simple, normal, rich): cities on the globe and the map; the Earth's relief shaded and, on the cartoon, mountains set on the real summits (NOAA's ETOPO1 relief), landmarks (Eiffel Tower, Statue of Liberty, pyramids, Big Ben, Taj Mahal, Fuji, the rockets of Kourou and Baikonur…), boats sailing, and in rich, whales, forests and penguins. Come closer with the wheel to see them.
• Contacts: the log's contacts on the globe and the map, as dots, dots with the callsign, or locator squares.
• Cities: all, only the capitals (with their name, their country's flag, or both), or none. The cartoon's relief shows more.
• Journal › 🌍 Session: choose a satellite and two dates, and all its passes play one after another on the globe (passes in a row or continuous time, fast or not), with the session's timeline and the SSTV pictures arriving one by one. A button plays an SSTV event's session directly. In the Journal, drag the globe to make room for the picture; the video keeps it where it is.
• Session speeds (page and video): three sliders, Outside the passes (the satellite far from the station, very fast, from ×10 in continuous time), During the pass, and Picture or contact (slow, to watch the SSTV picture being drawn or follow a recorded contact). The speed goes from one to the other smoothly. The session video shows the time, AOS · TCA · LOS and « AOS + 3:12 », with an adjustable text size.
• Journal: a Globe view beside Sky and Map replays the pass round the Earth; the contacts light up at their time with a line station → satellite → correspondent, and the SSTV pictures received land beside the station.
• All worked out in the browser, without the Internet.

• Stylish SSTV sheet, like an ARISS series poster: in Texts, Styled titles (ARISS series, Retro neon, Gold badge, Chrome title) dresses the title in one click, the number taken from the event; each text stays editable.
• For each text: a font (seven free fonts bundled with SatMe), an effect (outline, relief, neon, chrome, gold, gradient), italic, letter spacing, glowing rules.
• Background: the picture frame (fine white, rounded with a shadow, neon in the colour chosen), seven new backgrounds (the ISS above the Earth, its solar arrays, the Earth at night, a Spitzer nebula, and two drawn ones).
• + ISS poster: a stylish sheet ready made, NASA background, chrome title and twelve boxes in neon frames.
• With fewer pictures on the sheet, the boxes go between the title and the texts at the bottom, never over them.

• Quick setup at the first start: callsign, locator (or latitude and longitude), name, UTC or local time, language, minimum elevation, access from the network and port, in a few steps. Always there in Réglages › Démarrage.
• What's new: this window, at the first start of a new version; later from the help menu (?).
• New version available: once a day SatMe-PC looks at the latest release on GitHub and says so quietly at the top of the page, with its notes and the right download. Nothing is downloaded or installed by itself; turned off in Réglages › Démarrage.
• Réglages › Démarrage: access from the network (--reseau), port (--port) and data folder (--dossier) set from the page, with where each value comes from; taken into account at the next start, Redémarrer SatMe-PC where the launcher allows it. The command line always wins.
• Deployment (Réglages › Sauvegarde): the settings and the startup options in one file, without passwords or keys (unless asked), imported on another PC after a preview; a systemd or Windows file to start SatMe-PC with the session, to install yourself.
