K3 Mic Possibility

[N8XPQ]

I have been looking at the microphone jack on the rear of the rig. Would
this give one the ability to use a standard computer headset in place of a
standard microphone plugged into the front of the rig?

Yes.  You can use either mic port, but not both.  There is a menu setting to
choose the mic source, front panel or rear panel.

And I have tested K3 s/n 002 with a cheap Radio Shack Optimus Nova 79
headset plugged into the rear panel jacks.  Mic and stereo phones worked
just fine.

Is there a voltage for an electret mic insert on that socket?

Yes, you turn the bias voltage on or disconnect it in the same menu that
you use to select it.  Front and rear have independent bias voltage
toggles.   Thus, the K3 supports Electret (but not 48V ones!) as well as
dynamic.  I've used both types.
