To validate Wayne's suggestion . . .
K3 serial numbers 008 and 021 both exhibited this problem within two

several months ago. The problem occasionally got bad enough that the rig
would cut back to low power mode and report the PA over

have them ready to go if the problem starts up again. Replacing header
pins like these is something I've done many times before so I anticipate
no problems with the repair. This radio has performed extremely well in

K3 here owned for about 4 years.
