There you go again Larry. My comparision was between
CW and phone and you bring up PSK31 Now that I think of it,
I have tuned into CW signals that I could hardly hear and was
able to get the computer to pull it out pretty sucessfully.

The computer isn't anywhere near as good copying CW in noise as it is the
phase-shift (FM?) keying of PSK31. Simply amazing how it can copy signals
too faint to even make out with your ears....
