[Elecraft] Mic Noise

[Bob McGraw K4TAX]

Is this a dynamic mike with the bias turned on?   If so, turn the bias 
off.   I trust this is a mike connected to the MIC input on the front of 
the radio.  If you are using the front mike input and something is 
connected to the rear MIC input, unplug what ever is connected to the 
rear input.

Good luck in the VA QSO party.   There's lots of activity.
