Hi Don. If I remember correctly, their was a handi-ham letter that had
some tips for working PSK31. I will have to see if I can find it. A
couple of years ago, the late Tandy Way, K4YSN, was working with one of
the developers of the program, but I don't remember how mutch success he
was having.
As far as the cost, I think the software is free, or atleast farely
inexpensive shareware and the only other things you need is the cables to
patch your sound card to your rig.
Hope this helps and if I can find the Handi-ham letter that had the PSK31
stuff in it, I will send it to you.
