[Elecraft] KPA500 going into standby

[Rick WA6NHC]

George,

Did you look at the fault list stored in the KPA500?  You'll need the 
utility program to do that.

The KPA500 goes into standby on an error condition (SWR too high etc), 
so some info may  be there for the seekers...  A temporary failure 
(flexing antenna contacts in the wind, a bird landing in the wrong spot 
on the antenna) would trip the protection algorithm.
