[Elecraft] K3 malfunction

[Art Greenberg]

My K3/100 S/N 6522 was fine yesterday. Not so much today. No RX or TX (no output in TUNE).. A clue, perhaps, response to the OM; command doesn't show the KSYN3A is installed. (I get OM APXSDF------; but it should be OM APXSDF--V---;

I'm hoping for hints from experienced troubleshooters. I'll contact support directly as well.

TIA.
