[Elecraft] Mic Noise

[Buck]

I never use a microphone so here I am today trying to run voice in the 
Va QSO party.

When I key the mic, I get a burst of noise that lasts maybe a half 
second.  It does this even if I have the rig in "test" mode ie. no 
transmit.  So, I don't think it is RF.

I have tried adjusting the mic gain and changing mics - no luck.  It 
does the same thing using VOX except the noise cycles about every half 
second.

Anyone have an idea?
