ERR AT3 on K3

Hello all:

Over the weekend I was getting an ERR AT3 on my K3 when I first turn on the
radio. I did read in the manual about removing the KAT3, but decided just
to try setting the Config to "not inst" and the message no longer appears
during power up. The radio seems to work just fine without the tuner
"installed".

Is it likely the KAT3 is the problem or could it be something else? Also
wondering it is possible to have the KAT3 repaired.

Thanks,

Jed

Re: ERR AT3 on K3

Jed,

I would suggest unplugging the KAT3 and re-inserting it. Sometimes that
will wipe the contact pins of any oxidation and correct the problem.
Consult the K3 Assembly manual to see how to install the KAT3, reverse
the steps to remove it.

Repair is possible if you are capable of troubleshooting to the
component level. The schematics are available for download from the
Elecraft website.

If that does not resolve the problem, then contact [hidden email]
for further actions.

If your K3 does not have gold pins on the front panel, and they
are getting oxidized, strange error messages may occur on
power-up. Either do the gold pin mod, or hit the old tinned pins
with DeoxIT.

It very well could be the pin connections.

This weekend I started intermittently losing TX audio and when holding
TUNE, it would go into TX, display 0 watts, and put out no power.
Shutting the K3 and power supply off and turning everything back on
seemed to correct the problem once but then it started doing it again.
I removed the top cover and started checking connections of the 'TMP'
cable connections. Pushing on some of the ones on the KREF3 board made
the problem come and go. It didn't seem to be any particular one
though. I ended up removing the KREF3, cleaned the (tin) pins, put
everything back together and it has been working fine so far.

Re: ERR AT3 on K3

Don... I removed the KAT3, cleaned the contacts as you suggested. Seems to
be working fine for now. Thanks for the tip.

Dave... I previously had problems with the front panel pins. They have
since been replaced with gold pins. Haven't had further issues.

Mike... thanks for your reply as well. Sounds like it may be a good idea to
check all the pins in the rig at some point.
