[Elecraft] KPA500 powers up with LCD test

[Andy Durbin]

I did some more digging through my notes and found "D results in KPA500 displaying MCU LOAD.   Recovery from accidental D requires rear power off, rear power on, then front panel power press".

Accidental sending of D does not seem to explain the KPA500 powering up with LCD test pattern.  Reload fixed the problem but I still don't understand what caused it.

I suppose I should disclose that my KPA500 is, and was, loaded with development firmware not ver 1.54.
