Brett,
All three are desk mics designed to work with Kenwood radios. The MC-60A is
the only one currently available from stores. Check for prices at your
favorite store. It has a high/low impedance switch, and I think it has a
preamp although I'm not sure. The MC-80 doesn't have a high/low switch, but
it does have a preamp and an adjustable gain control on the back of the
base. The MC-85 can run two or three radios off its multiple outputs. I've
never seen this one, but I've heard it's good. It may have an equalizer,
but I'm not sure.
Steve
