On one of my K3's the Powerpole receptacle got flaky. Turn the radio on,
and then wiggle the plug to see if it drops out. I resoldered where
the receptacle pins mate with the circuit board inside, but I still had
to use a tie-wrap to hold the plug in a certain position. I'll fix it
the right way one of these years.
Good luck!

Hello all:
Earlier this week my K3 shut itself off while it was in receive mode. It
had been running for about 20 total minutes at the time it turned off. I
had just finished a 15 minute QSO. The Tx power was 10 watts.
When I tried to turn it on again, the display briefly flashed for a few
seconds and I could hear a slight buzzing sound from within the chassis and
it went off. I waited for a short time and tried again. The K3 display
flashed for a few seconds along with the buzzing, but would not stay
powered. I tried this one more time, but the display flashed very briefly,
buzzed and then off again.
This morning I could power on the K3, but I didn't let it run very long
before I powered it off. It would seem this is some sort of heat-related
issue.
It's serial number 2826, but it's had several mods over the years including
the upgrade on the receiver.
Any ideas would be appreciated.
73,
