[Elecraft] OT: Whole House Generator

[N4ZR]

FWIW, I have a 16 KW Generac propane generator.  It uses load-shedding 
modules with an automatic transfer switch, so that if my load exceeds 
capacity the 240-VAC loads will be shed one at a time.  I figure the 
chances of my simultaneously running the dryer, the oven, the AC and my 
amplifier are pretty low.  Haven't noticed any problems with the 
waveform, but haven't really looked.

73, Pete N4ZR
