Err AT3

[Gary Smith-2]

Curious little bugger; since yesterday
when I turned the K3 on and got a message
on start-up saying ERR AT3, I find this
happens all of the time now.

In this error message state I can not
transmit. What it takes to resolve this is
to tap on a function switch like band
change, mode, split Ect. and it
immediately resolves to a perfectly
working K3. It was recently back home for
all upgrades/updates and has been working
flawlessly, till this condition.

Any suggestions on what I might do to
resolve this before it mutates into
something less easy to resolve?

Thanks & 73,

Gary

Hi Gary,

i had the same problem a few weeks ago.

Peter (DL2KI) by the German Elecraft service said that it might be a contact problem.

I then removed the KAT3 and cleaned the contacts with a glass fibre brush. Then everything was OK.

It could also be a contact problem on the connectors between front panel module and main unit. The signals of the ATU are processed by the main processor on the FP module.
