[Elecraft] FW: FW: K3: KPA500 on a generator?

[Brendan Minish]

The KPA500 has a linear PSU and uses a conservatively sized toroidal
mains transformer followed by a pair substantial filter capacitors 

It's over and under-voltage protected by firmware, I strongly suspect it
would not have any particular issues with a poorly shaped input mains
waveform. 
If the generator voltage regulation is very poor indeed then the
firmware may take action to protect the KPA500 from damage by taking it
off line or protectively shutting it down. 

I hope to have my KPA500 on line for the UK elecraft net tomorrow
morning.
