[Elecraft] Heil Proset Plus and K3

[Don Wilhelm]

Bruce,

The High and Low in the K3 microphone menu refers to the microphone gain 
range and has no relationship to the "bias".  The bias voltage for the 
front panel jack is sourced from +5 volts while the rear panel jack is 
sourced from +8 volts.  Most electret mics will work with either voltage.
