Toby,
You are correct. If I have the monitor set above about 35 there  is no
thumping. If I set it down to about 12, where it usually is, there is
thumping. Tried it with the internal speaker, external Kenwood SP-850 and
Heil headphones.

NO,  this is not what is going on.   If the sidetone monitor is turned up to
a good fairly loud position,  you will not hear the thumping.  IF it is
turned to what I would call a comfortable level for my ears,  then the
thumping occurs. 

It is not dependent on AF gain being set excessively high,  but is rather
dependent on the monitor setting is relation to the AF gain.
