[Elecraft] Killed the KPA500 :)

[Raymond Sills]

Hi guys:


No mention was made of whether the transceiver was being operated by the front panel or via CAT commands.  Maybe something in some running software sent an "operate" command when it should not have.  It'll be interesting to know what the cause of the incident turns out to be.
