I was playing with HDSDR+ExtIO and Ettus USRP1 to track a BPSK signal. In the end I successfully heard the signal.
But I would like to see the data, I mean the raw data (HEX values). For that I tried fldigi in which I just selected BPSP-31 under PSK (in the Op Mode menu).
I've used a cable to forward audio from speaker to mic and I saw something in the waterfall but cannot get any data.
Which things should I check? (Any lower level tutorial?)
I know the source operates at 1200bps (symbol rate) but I'm not aware of line coding, preamble (, et cetera) at this moment.
Also, i successfully experimented to decode some public BPSK sounds:
