Gordon, I hope you find? the source of this. I have scoped various points and think it has something to do with the CODEC.? I have not been able to pin point the source at these low levels of amplitude. I see more scope probe noise pick then actual signals.

Sounds good Gordon.
My focus now is the RX audio to reduce the high level of noise that exists even without a signal as well as addressing the low level of audio output on receive.
