[Elecraft] ERR AT3 on K3

[Dave Hachadorian]

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.

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 
support at elecraft.com
for further actions.
