[Elecraft] MH3 mic with the K3?

[Don Wilhelm]

Ron,

I am not going to give you a step by step set of instructions, but the 
K3 (no hyphen) manual has the pinout for the 8 pin Foster jack, and the 
KX3 manual has the pinout for the MH3 mic plug.
Match up the AF lines and the shell (AF ground) with the 8 pin 
connections, and match up the PTT on the MH3 plug ring 1 to the PTT pin 
on the 8 pin.
The PTT return is a little more "tricky" and you should connect the MH3 
ring 2 to wither pin 7 or pin 8 on the 8 pin Foster plug.

You will need to turn bias on in the K3 menu, and the UP/DN buttons on 
the MH3 mic will not work - but you should have audio and PTT.

73,
Don W3FPR
