[Elecraft] K3 Microphone Connection

[pastormg2 at verizon.net]

Good Evening,
I have a Heil HM-12 and what like to connect the microphone to the K3 Microphone connection in the rear of the radio.  It would be a XLR 4 to a 1/8" mini plug. I don't know if Heil even makes such a cable.  From what I hear most headsets that heil manufactures has a 1/8" mini plug at the end of the cable.  I installed a DVK this morning and now the microphone connector in the front of my K3 does not work. Per Elecraft it has something to do with the DSP Board. Of course if I connect the microphone to the rear jack it bypasses the DSP board. Any suggestions, would much appreciated. Mark Griffin, KB3Z
