[Elecraft] MH3 mic with the K3?

[Don Wilhelm]

Ron,

No.  Pin 6 is NOT bias, but a source of 8 volts.
Bias to the microphone is applied through a resistor, not directly from 
a voltage source.
All you need to do is turn BIAS on in the MIC SEL menu.  See the K3 
manual for the button to tap to toggle the bias setting.
