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

[anthony sharki]

had the same problem with mine, not able to break pileups and very few
contacts. trip to service center checked out ok and found problem was at
the mic impedance setting. use the LOW  impedance setting and follow
directions in manual. works like a champ!
