Gerry responded to me off-list (below). I think your "Siri translation" meant reseating all plugs on the K3 and and maybe "Colex" was "coax." In response, yes I think I'm ok on those two points but will keep my eyes open. Interesting that a couple other guys are seeing this. So far I think it's only 20m; again, I'll have to keep a better system log.
Somebody else mentioned the Anderson pole connector - I've been in good shape for several years so I expect it had been assembled correctly; but I'm wondering if the connector surfaces are known for oxidizing? Bruce / KE1CY "I have not been following all of the messages in this thread, so if I am repeating something I am sorry. Have you checked grounds? Also have you checked to make sure that all of the Colex connectors are tight and have you tried receiving all of the plugs on the K-3?
