[Kenwood] TH-F6A Problem

[Gary R]

Well it's happened, while in QSO today my F6A decided not to transmit.
All and I mean ALL settings are fine, display shows normal transmit
indications however, I can not raise local repeaters on 2 meters or 440,
220 works fine. I tested the 2m and 440 output on high power into my
Bird wattmeter and load and, no output, zero, 0. Anyone experienced
this? I've performed a full reset and still no output on 2m or 440 only,
220 works fine. Before I send it back (not looking forward to that) I
thought I'd ask.
