[Elecraft] Running KPA500 on generators.

GM Neil,

I regularly use my KPA500 on a generator.  This week, I'm using it on a
Cummins 3.5 KW in our RV.  One year ago, I used it on a Harbor Freight
Predator equivalent to the Honda 2 KW inverter.  It works well on all three.

The only caveat is when operating CW, I needed to avoid using the "Econ"
mode which sets the idle speed much lower.  The Honda and HF versions didn't
like the sudden change in current draw and would fault.  As always, check
the HV supply reading on the KPA500 to determine if a different transformer
primary setting is necessary under load.

I want to add the KPA500 manual describes the different primary tap
settings.  There seems to be a lack of manual-checking going around these
days.  The updated manuals (firmware changes) are invaluable tools! 
Fortunately, Elecraft allows making notes in the PDF versions of their
manuals (copy and paste) which is much easier to accomplish than in the
printed versions.

73, Bill, K8TE
