YES.   VERY often, I hear audio that is so badly distorted that it is 
muffled and hard to copy. The fix is VERY simple -- TURN DOWN THE AUDIO 
GAIN!  The directions Don has given you (and that are in the Elecraft 
manual) are exactly the right way to get there. As to compression,  I 
like to see no more than about 10 dB of compression on voice peaks. Use 
the meter display that allows you to see ALC and COMP.  The NUMBER that 
you need to get there doesn't matter. What matters is how high the COMP 
meter goes.

All of the Heil mics I've heard have been harsh, so the last thing I 
would do is add high peaking (that is, boosting the higher bands).  I 
WOULD roll off the lower two or three bands the maximum amount.

BTW -- you should ALWAYS adjust TXEQ BEFORE setting Mic Gain and COMP, 
because TXEQ can have a HUGE effect on those settings.
