As a newcomer to this mode I am really amazed what can be done.
To get going was quite easy for me, just a few hours of reading and testing and I was on the air with my FT-450...
Beeing a QRP enthusiast I really would like to use mysmallwonderlabs PSK30 on WSPR.
The rig has a fixed "dial frequency" of 103940 so the WSPR audio will be 600 to 900 Hz. Can the software be modified to use this as audio input?
