Tom,
If I remember right, you are running a Kenwood TS-2000. If you are
using the Kenwood desk mic with the curly cord (forget the number), you
may have to run a wire from the body of the mic unit to the radio.
This is a common problem and I've seen it reported on a number of
Kenwood lists over the years. Even our SK friend Kevin K7RX dealt with
it.
Even if using a different mic, . it wouldn't hurt to try a ground
wire between mic and radio. Kenwood has some sort of floating ground
involved in the mic connection and sometimes a good chassis ground
between mic and radio will do wonders.
