RE: "And, as always, the standby: soundmodem."
But why?
A few guys have done side by side tests with soundmodem and Direwolf(and a few others)...
Direwolf decodes ~10 to 30% better.... Why waste time with soundmodem??
I'm sure soundmodem was great in its day... but does not have the latest code for the newer equip.
Now if that is all that will run on old equip. ,,thats fine....but a Pi will handle Direwolf.
