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

HNYto all!
Has anyone made an adapter cable to allow the MH-3 mic to be used with
the K-3? I acquired a KX3 with its mic, and a K-3 without a mic, and
would like to be able to use the same mic on both rigs.
