The overdrive occurs in the audio drive
to the mixer.? There is no gain control for the microphone. I
found on my board that the gain was too low. You can look at the
mixer input with a scope and see when the audio starts clipping (I
didn't validate this). Another test is if your audio reports are
clean, you probably are okay, if you start to distort due to
compression, you are over driving. I can't overdrive on my board
because I put an AGC on the mic and its output swing is limited.

Thanks for the
concise explanation!
As for overdriving your audio, is this something that can be
solved by dialing down RV1 to reasonable levels, or are the spurs
created before that stage?
