You're a ham, pull out your soldering iron, and the manuals for the K3 
and the headset to see what pins are used for mic and earphones and make 
your own. XLR4 connectors are widely available and easy to wire. So are 
1/8-in plugs if you buy good brands like Switchcraft and Neutrik. My 
favorite vendor is Full Compass.  Part numbers for the 1/8-in plugs are

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.

Can't help you with that part of it. I use Yamaha CM500, which plugs 
into the rear panel connecters. Far superior and MUCH cheaper.
