Hi, Steve. Well, I finally got PSK to receive, at least.Figured out
the modes on the 480, went to CW mode, held the mode button, and got
into FSK mode. Actually copied a few snippets of PSK31. So, we're
getting there, we're getting there. Only problem is that my
bandwidth doesn't go to 3000, unless I'm missing something.--Matt, N1IBB.
