MC-60A, currently sold, does have an amplifier in it but it can be switched
off. The MC80, which I have and love, also has an amplifier, can be adjusted
but you shut it off, you shut off the hole mic, and the MC-85 is pretty much
the same thing but will run up to 3 radios so has a couple more buttons on
it to switch radios, but the basic design is exactly the same as the MC-80
