[Elecraft] Mic problem

[Jack Berry]

I have a Pro-Set mic that came with the purchase of a used K3, s/n #3012 for 
reference.  The mic seems to be nearly dead and I wanted to make sure that I am 
not  doing something wrong before sending it to Heil for testing and repair.

Even with the gain full up and the mic right next to my mouth I can't  move the 
ALC but do hear my voice in the head set with monitor volume up  full. I have 
tried it through both the front and rear mic sockets and  another Heil mic works 
fine with the radio.

Any suggestions?
