Hi Dave,
I'm not sure what to say about printing PSK. With Digipan I just click on
the trace and it prints! Maybe your audio level isn't correct, or your
filters are too tight and/or IF shift off. When I copy PSK, I set the filters
as on SSB (2.0 KHz) Only if there is one very loud guy swamping the
AGC do I go narrower.
