K3 KAT3

[Larry Boekeloo-2]

My K3 seemed to develop a problem on 20 meters this evening.  Trying to
work Marquesas this evening on 20 cw the K3 would not transmit and
basically no receive.  I checked every other band and all worked as usual.

The moment the radio went into transmit, I received Hi SWR on the screen
with or without the antenna tuner

I then reloaded all of the software and still nothing.  I tried to force
the tuner into auto tune by selecting my 160 meter dipole for 20 meters and
still nothing.  I finally went into the Config menu and disabled the KAT3.

All now works.  I never use the KAT3 anymore since I have the KAT500 and
KPA500.  Has anyone else had the KAT3 fail on 20 or do I need to open the
rig up and reseat all of the contacts?

Thoughts?

Larry, KN8N

Larry,
Are you sure you didn't have ANT2 selected when you really should have been
on ANT1? Or the other way around.
When you disabled the KAT3 I think it defaults to ANT1.
I've had this happen before. All bands work but one. The one that doesn't
work has the wrong antenna output selected.
Now how did it get switched from ANT1 to ANT2? Who knows for sure, but I was
probably intending to operate RX ANT button or some other function and hit
the ANT button by mistake.
