Mic problem

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?

What type of Heil Proset is it?

If it is either the Heil Proset Ic or the Elecraft Proset K2/3, then you
need to turn bias on because it has an electret element.

If it has a dynamic element (often marked with an HC4 or HC5
designation), then no bias is required (and should not be turned on).

As you can see from the above, there are many types of Heil Prosets, and
we would have to know the full microphone designation to make any
certain statements.

In the main Config Menu > Mic Sel, I plug the mic into the front panel
and use FP-H and no bias. Mic gain 18-20. Unless you have an Icom
cartridge in the Pro-Set. That would require bias.
