Tom,
The Amp in the MC60A is needed on the newer Kenwood rigs. On my TS2000 I
have to have the mic amp on to have enough mic gain to use vox. There is an
impedance switch on the Mic and the lower impedance setting will give you
better bass response though the output of the mic will be a little lower.
The lower impedance setting also reduces RF getting in the mic, but
grounding the mic case does the best job on resolving that problem.
