Well, I finished installing sketch 1.17.1, added the function switch, and
did the PTT sense wire-up. All went well, all new functions work, but now
I get a strange noisy loud interference from about 7215 to 7265. It almost
sounds like some kind of oscillation, (not a squealing oscillation) It
gradually starts at 7215 and gradually stops at 7265. It basically wipes
out any signals in this part of the band. Any ideas? Suggestions?
Do you still hear this noise when the antenna is disconnected?
Is it in both LSB as well as in USB mode?
