This morning just for yuks, I also temporarily disconnected the ground from the rig entirely while also connecting only to a dummy load, so there could be no path to ground at all, let alone multiple paths. No change.
I guess the next things I'll probably try are a full factory reset, and then perhaps popping it open to make sure nothing has come unseated. But first I'll drop a line to Elecraft support too. I've seen a number of people post about similar problems that either magically resolved themselves or ended up being a fault on the audio board.

Belief in something doesn't make it real. And if you have to lie to support a position, that position is not worth supporting. ______________________________________________________________ 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
