[Elecraft] Bizarre K2 keyer issue

[Cameron Francey]

FYI,
I had a very similar issue last month, I keyed down and I got an error code on the display, I cant remember exactly what one it was but it wasn’t listed in the manual.
Anyway, all I done was took the key plug out and reseated it and all was well again.  I suspect a high resistance connection on key socket confuses the micro controller in some unexpected way.

It's the darndest thing - but I'll take it!

I don't have the diodes. I don't have SSB, or a mic jack. So...I did the
test with the shorted stereo plug. Everything worked fine.

So then, I plugged in my paddles, and - everything worked fine.

Hooked up my new delta loop, worked France with 5W, got a 599.

So thanks, Don, for the long-distance exorcism. May it last!
