[Elecraft] K3 Crackling audio with Noise Gate running

[Edwin Johnson]

Hello Lance,

Make certain if the Heil is _not_ an IC type (electret or condensor mic) that 
the bias is off. His mics are dynamic and you don't want to feed the dc 
voltage into those with the bias setting turned on.

Just for your information, I'm using a BM-10 with the #5 element and my 
settings are level=High, bias=Off, gain=15, compression=10. This seems to work 
with my voice and equalizer settings and splendidly for vox use.
