> My K3 is quite an early unit, S/N 298. Recently upgraded with new synths
> KRX3A and KXV3, I also have a P3 connected to the radio. A while back it
> failed with a shorted smd capacitor on the K3REF board causing loss of
> TX bias voltage. Today it has lost both receive and transmit and I am
> thinking it might be from the same module. Here's the situation.

> Rig powers on and appears to work normally except soft noise from the
> speaker, no band noise to speak of and no signals. P3 shows plenty of
> signals, S9 plus on FT8 freqs but nothing heard other than soft noise.
> Tuning works as signals move in the band scope. No sub receiver signals
> either and no TX output. Have not checked transverter output but expect
> to find nothing there.

> P3 take off at IF output so everything is clearly working up to there.
> DSP seems to be working as width and shift cause the expected changes in
> audio. S meter reads dead zero, no movement.

> About the only common point I can see is the K3REF board so it would

> earlier work I wouldn't put it past being a user inflicted fault, but
> that repair was a month or more ago.
