Thanks, Jim, got the message.

Now, I would like to use the K3+KPA500 with an unused Briggs and Stratton
2kVA generator that I fancy for portable work.   It's probably the last of
the "old style" ie no inverter technology.  I don't expect Elecraft to test
their kit with all and sundry generators that were ever built, but there
might some lore about VA ratings and on/off ratios.

Any advice welcome.
