Excellent! Wow! thanks everyone for the ideas!
I’ll start my investigations!
What was amazing to me was that after listening to my own signal and hearing how distorted the audio was , that stations on ECARS net had even able to discern my callsign. They accurately reported “ Jeff, something is really wrong with your audio”
Thanks again for the various ideas, possible causes, possible solutions, prevention!
BTW it was working well for a while. Maybe it was an over voltage damage. I’ll check my lithium ion battery pack voltage.
