On the 10utc pass this morning, while the transponder was on and in use:
I learned that reducing the width of the cutoff filter in Foxtelem program made it so I could copy the subaudible telemetry packets with the Funcube Dongle Pro. Reducing from the default 200 Hz to about 180 or 175 seemed to work here. It shows up as a decent eye pattern after that.
Another FYI-When playing back an IQ recording via SDR#, it seems a bit more forgiving, working well around 175-200.
Suggest folks experiment for best copy! Share hints here, please!
