Who uses the Elecraft hand mic? I do and mic gain has to be set low; i.e. around 8 or 9 to prevent clipping and flat topping  as viewed on a monitor scope.  This is with mic sensitivity set to low in the menu.  I was once told that the hand mics are a tad hot, but mine seems to be excessively so.

Regardless, my comp is set to 15 or 20 and I get excellent audio reports.

I use the Heil MD2 microphone which has an electret element.  I have both
compression and mic gain set to 25, and mic set to front panel low with
bias.

I have far more 'talk power' than I have enjoyed with any previous radio.
