Thanks for your reply here and the copy by e-mail. I seem to have<br>
achieved the impossible though and now have my Red Pitaya receiving<br>
WSPR on LF with no VAC installed, just using the on the motherboard<br>
sound card and stereo mix. I can do this using HPSDR and HDSDR<br>
firmware on the SD card. Maybe you meant I would need VAC to RX and<br>
TX? I am only interested, for now in RX'ing. Have I done something<br>
that is less than optimal here? It seems to hear as well as other SDR<br>
receivers or my TS-590 and i have found no gotchas so far? Thanks for<br>
all the tech help you selflessly give on various forums!<br>
