You can try to replay the file at: http://janvgils.home.xs4all.nl/download/QB50px/ to see if things are working.
Hello,
Here's a follow-up to my ongoing struggle to grab this bird. I downloaded the above file and ran it in SDR# and confirmed that Soundmodem was seeing it fine -- it decoded the 1200 baud BPSK and sent it to AGW Online Kiss. I saw KISS frames scrolling up the console like gangbusters. No problems there.
So tonight I sat down and recorded a full QB50p1 (EO-79) pass with this same configuration, 1200 baud BPSK. I saw the trace in the waterfall, and saw the little "Ch. A" light come on when the trace went past the reticule.
But no data. I could not pull a single packet out of it.
I recorded the entire pass' I&Q and have put it up on my Dropbox in case anyone would be kind enough to run it and tell me if the signal is simply too weak to get any data out of.

For reference, the antenna used is a VHF/UHF discone.If the answer is simply "signal too weak, you need more gain", then at least I'd be making some progress in understanding it. Certainly *looked* strong enough.
Tnx es 73
