Jim,
Could be the radio, but I'd look for RFI getting into the headphones first.
Make sure you have a good RF ground and every piece of equipment
is going into a common ground point (not daisy-chained). Also, you might
mention to the list what your antenna setup is as that could use
improvement.
I doubt you are hurting the radio. You are probably getting RF pickup in
the headphone cord.

Casey
