Thanks to Rick, N1RM, and his expertise in tracing circuits, my K3 is back
in FB working order. We found that a switching diode on the bottom
(fortunately) of the RF board had failed. (I think it was D25.). It was a
low cost fix, and with Rick's surface mount skills a replacement was soon
installed.
Rick's main expertise in working with ham equipment is repairing ACOM amps,
but fortunately he had the ability and equipment to help solve my K3's
problem.
Thanks for all the ideas and feedback here on this reflector.
73 - John, W4AU
