[Elecraft] Using a PC headset with K3, connections reverse at rear MIC jack?

Alan,

The rear mic jack is a mono, not stereo, jack.  It will short the ring and 
sleeve together.  Audio is on the tip, as is the voltage.  The mic should 
have a blocking capacitor to isolate the audio from the voltage.

This is standard for every radio I have owned.  If a stereo jack is used, it 
would be for PTT, not a separate bias connection.

Why would Elecraft do it this way, so these gaming headsets don't work
without an ugly crossover adapter? Is there any non-soldering way to
change the connections on the rear panel Mic jack?

Thanks,
