[Kenwood] Kenwood TS-930S Microphone Impedance Setting?

Tue, 8 Jan 2002 20:03:31 -0600

Please confirm for me: Presumably this advise is applicable to KW 950SDX
using the MC 60 mike?  Thats what I have, but was using the 50K setting. IF
that is wrong for this radio too, then would like to know.  Thanks.
