What's new in 1.8.3
- The DVB card's header on every mode. Each decoder's panel now opens the way DVB-S2's does: a title bar with the mode, the space-segment frequency and the symbol rate (the VFO's width for a mode with no symbol rate), green once the carrier is locked, half lit while it is not, grey while it waits. Under it, a demodulated carrier's modulation and code in large type with its Es/N0 beside it and on a bar, then Es/N0, Eb/N0 and the residual offset; the analogue modes, Spectrum and the IQ recorder show the VFO's level on the bar instead.
- Less repeated in the modem cards. The TPC, Viterbi, FastLink and generic PSK cards no longer list the carrier's lock, Es/N0, residual offset and symbol rate again: the header has them.
Both pictures are the test signal decsat-scene_8Msps.cs8 below.
Portable Windows executables for 64-bit Windows 10/11, nothing to install (static C runtime).
| File | What |
|---|---|
decsat-gui.exe
| Desktop app: wideband waterfall with VFOs (DVB-S2/S2X → GSE/IP or MPEG-TS, DVB-S, satellite modems, DVB-CID, generic PSK/QAM, IQ record), IQ files or a HackRF One; a DVB-S2/S2X transmitter (MPEG-TS to the HackRF or a file) |
qo100-beacon.exe
| QO-100's 400 bit/s PSK beacon from a sound card: waterfall, frames, text and housekeeping values |
decsat-tx.exe
| Transmitter: a webcam and microphone (or a video file) encoded live in H.264, H.265, H.266, AV1 or MPEG-2 by ffmpeg, on a DVB-S2/S2X carrier with QO-100 presets, to the HackRF or an IQ file (needs ffmpeg) |
decsat.exe
| Command line: decsat scan, decsat decode, decsat analyse, decsat scene, decsat cid, decsat test-signals, decsat tx, decsat record, decsat modcods
|
decsat-server.exe
| Headless SDR server: serves a radio at the dish to decsat-gui or decsat over one TCP connection (see docs/REMOTE.md)
|
decsat-server-app.exe
| The same server in a window: double-click, choose who can connect, press Start |
decsat-scene_8Msps.cs8
| Test signal, 8 MS/s, 4 s: DVB-S2 (IP over GSE, and an S2X ACM carrier with MPEG-TS), DVB-S, a TPC 2964 modem carrier and a CW tone |
decsat-cid_3360000sps.cs8
| Test signal, 3.36 MS/s, 30 s: DVB-S2 QPSK 1/2 at +700 kHz with a DVB-CID under it (identifier and position decode) |
Open a test signal in the GUI (Open IQ…; the sample rate is in the file name) and click a carrier, or run decsat test-signals to make them yourself (tests/README.md).
A HackRF One needs no DLLs (it transmits only when armed: see the README); on Windows it must use the WinUSB driver (Zadig, or the one the official HackRF tools install). IQ files need nothing.
Windows SmartScreen may warn on first start because the files are unsigned ("More info" → "Run anyway").
