Dick,

The headphone part will work just fine. For the mic part, I believe the plug on the mic is a mono plug which will activate PTT as soon as it is plugged in, so you will have to make up an adpater that wires jack tip to plug tip and jack shell to plug shell (no connection to the ring at the plug end). If you want to add another 'tail' to attach a PTT switch, then it connects between the plug ring and the sleeve.

The elements are compatible and need to have bias turned on.

Note that a mono to stereo adapter that you can purchase in a store will probably not work because most of them wire both the tip and ring of the stereo end to the tip of the mono end.

Will the Heil Proset-IC PS-IC that I am using for my Icom 7000, work with
the KX3.  Are the microphone elements compatible, or am I going to screw up
either the KX3 or the mic?
