I've been tracking doppler by hand. Seems to work OK but it's very

Jumps per se are not a problem. I.e., if
Is it possible to record all the transmissions in a single wave file
using FCD and separate the FM, telemetry, ssb, and SSTV later after the
bird is gone?

Hi Floyd,
Yes, you can. Recording the full 80kHz bandwidth for a 10 min pass
(duration of ARISSat-1 passes, roughly) creates a BIG wavefile around 250MB
in size. You can play it back and decode whatever you want, whenever you
want.I've been doing that regularly, which results in about 1GB

Hi Henk.
I've had some issues with decoding BPSK too. Worked fine on the first day,
then unable to decode anything.
Eventually I reloaded the software and played a wav file through the system.
Finally it began decoding again. I don't really know what the problem was. It
still will not send
