If, as you have told us, the sidetone is clear and loud, then the odds of it
being in the microphone/jacks/PTT switch are nearly zero. My bet is an RF
problem of some sort.

And why would you consider some sort of "debounce" circuit? DO you have a
clue what a debounce circuit does?

If it was a broken/loose wire in the mic circuit I would think I would
not get a good sidetone in the headset. Have seriously cleaned both of
the mic jacks but now that you mention it I'll bet it could be the PTT
button (duh!). I probably need to make a debounce circuit or something
if possible. At least I could try taking a passenger to try the rear
xmit button. Thanks for the "wake up call".
