I just received my first HS data from AO-92. Nothing was decoded using FoxTelem, but I got the IQ file to play around with. It was a low pass for me, so signals were only 20 db over noise using my AirSpy mini. That might be too little, although I can receive Falconsat-3 at those levels without any problems.
What are the settings to watch out for decoding HS data (deviation, soundcard, Foxtelem)? Or should it "just work"? The only difference I can see between FS-3 and AO-92 is that audio from GQRX is going out to PacSat Ground Station via UDP and Foxtelem gets it from GQRX via a virtual audio loop (set in Pavucontrol).
Still exited to receive AO-92 with HS data for the first time. I saw on Twitter that JA0CAW did get part of an image, so for him it did work.

For anyone decoding images and using FoxTelem with Doppler Tracking enabled I would appreciate any feedback on how high speed data is being decoded. Especially if you decoded camera frames in previous runs, like last October, and can compare.
This was a new feature and previously tracking of the high speed signal was not great. Let me know if it is better (or worse!)
