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. 73, Wolfgang DL2KI -- View this message in context: http://elecraft.365791.n2.nabble.com/Err-AT3-tp7594368p7594398.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
