[Elecraft] Microphone

[Don Wilhelm]

Bill (and all those contemplating using a non-Elecraft branded 
microphone with the K3),

The Heil headset can be plugged into the rear panel jacks - no adapter 
is used.  Set the menu to use the rear mic connector.

The front panel wiring pinout is shown in the K3 manual on page 13.  The 
Elecraft MH2, MD2, Proset K2 microphones are wired with this same pinout. 
Heil dynamic microphones will work using a Kenwood adapter because only 
the AF, PTT, AF return and PTT return lines are connected.
Heil microphones with an electret element *may* work on the front panel 
jack if a Kenwood adapter is used.
Kenwood non-amplified dynamic microphones will also work because they 
only use the same pins as above.  You can easily check a Kenwood 
microphone by inspecting the wiring in the mic plug - if neither pin 5 
nor 6 is connected in the mic plug, it will work.
Yaesu and Icom (and others) microphone plug wiring is entirely different 
and will not work unless the mmicrophone plug is re-wired.

If you need assistance in de-ciphering the wiring on a non-Elecraft 
microphone, consult the information from the microphone manufacturer.  
Another good resource for microphone pinout information is the list 
provided by G4WPW that can be linked to from
