  1. @Quantensalat At least #OpenWebRX+ and #QSSTV support P5 and P7, so there should be enough common software around to decode them

  2. Why does QSSTV have libindi (astrophotography camera library) as a dependency

  3. @aregsstv "Wasn't watching the S-meter"…

    20m definitely seems to be the better band QG62→PF95.

    That image was via QSSTV.

  4. Did some more experiments with #SSTV this afternoon.

    This time, using #QSSTV. Not sure why, but modulation is well down. Receive is fine. The command I used last time is fine too. Just QSSTV is "low".

    I had to also make up my own #rigctld implementation, enough to fool QSSTV into thinking it was the real deal, so I could use that to control the GPIO pin on the UDRC-II for PTT. This is hacky and nasty, but it's enough to trick QSSTV.

  5. Well today trying to receive the #ISS #SSTV experiment yielded nothing to be heard on 437.800MHz over #PF95. and one the passes was 60°+ in the sky. 😿

    my setup was FT-857D, X50M antenna, digirig, laptop for hardware side. Software had #rigctld, #gpredict interfaced with rigctld to control the doppler, and #QSSTV to do the decode of the signal.

  6. Haciendo pruebas he descubierto por qué las fotos aparecen distorsionadas cuando recibes las imágenes desde la cinta.

    En la imagen vemos dos pistas del mismo audio con la misma foto. Arriba es la que está grabada desde el cassette ¡Puede verse que tiene ondas! abajo la que fue grabada directamente con Audacity en el PC, que está perfecta.

    Aquí la foto (grabada con Audacity).
