[Elecraft] ERR AT3 on K3

[Don Wilhelm]

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.

73,
