[Elecraft] K3 - KEY OUT problem

[donovanf at starpower.net]

Hi Pete, 


Perhaps more important: how did this unusual failure occur? 
Unless you can figure this out with a reasonable degree of certainty, 
you're radio is likely to make multiple trips for repair. 


One possibility is that you connected a relay to the KEY OUT 
connector, but the relay didn't have a snubber diode across its coil. 
That could cause enough of a spike to damage your radio. 


Another possibility is that you plugged the incorrect cable into the 
K3 and excess voltage on that cable damaged your radio. 


Good luck!

Thanks to everyone who responded. I've now written to Elecraft Support, 
and anticipate that it will have to go back to the mother ship.
