Hello Larry:

Any mic can be wired to any radio. It may take a little doing tho.

I would want to know is the MC80 mic a mic that takes a voltage to
operate, like 9 or 12 volts?

Some mic's have switches to move the VFO or memory channels up and down
and these are not required to make the mic wic work. So not all the
wires will be used.

Looking at the diagrams would help.

Is it possible to wire a Kenwood MC-80 Microphone to work on a
Yaesu FT680R? I have been using the 680 as a six meter Base radio.
The Yaesu has nine wires and the Mc-80 has seven, would like to hook up
a desk power mic.
Could deffinetly use some experienced help.
Thank You, 73s
