I run mine on 240V in the shack and on 120V in W6GJB's contesting 
trailer when we're running on a Honda generator.

The only potential issue with 120V operation is excessive voltage drop 
in a long and undersized run from the breaker panel to the outlet where 
the KPA500 is plugged in. This can be partially compensated by changing 
the transformer tap, as detailed in the manual. It's pretty simple -- 
remove the top cover, change the tap, and close the cover.
