[Elecraft] RF in Microphone

[Don Wilhelm]

Jim,

Your mic gain is on the high side.  If you have the mic gain range set 
to "Low", try changing it to "High" and lowering the gain to the 10 to 
15 range.
Turn compression to zero while the mic gain is adjusted for 5 to 7 bars 
(7 on peaks) on the ALC meter.  After making that setting increase the 
compression to whatever you desire - most like to run compression in the 
10 to 15 range.

See if you can borrow someone who can see the ALC meter while you talk.
Set the K3 to TX TEST so you don't send RF while you make those adjustments.

73,
