[Elecraft] KX3 not operational after move to Florida

[ken at arkayengravers.com]

Hi guys. Well the move to FL went okay, but it looks like the KX3 does 
not like the sunshine state.
I was setting up for the 10 meter contest, and the KX3 was acting 
'funny'. When I turned it on, the display showed ERR KEY, with no key 
plugged in. Tried EE INIT and reloading the configuration and firmware, 
no change.
So, I removed all the modules, and plugged in the KX3 with a dummy load. 
The display shows d=001 and ERR KEY, nothing else is plugged in.
Firmware is mcu 2.76, dsp 1.50. I can eventually get it into menu mode, 
but it locks up at 'LCD TEST'. Also, if I put it into cw mode, I get a 
string of dots, which does not go away until I shut the rig down.
I think it needs to go back to Elecraft.
