Well maybe more shacks should have that capability. It is not expensive as here:

Certainly not lab grade but good as even just a shack line monitor or bench
tool.
Another useful application, and I always have it on to monitor the output of the
backup generator. I can see output voltage and line freq. Seeing within a few
cycles of 60 lets me know that engine speed is being regulated correctly.

Oh my! The KPA500 is more efficient than you give it credit. Since few have
instruments to measure ac input parameters, will volunteer actual measurement
figures.At 650W output into 50 ohm load, highest VA recorded was at 14.1 MHz at
1166. Watts 974 with a pf of 0.83 or 83%. AC input amps 10.3. Awesome!

Tom,
That 3000 watts I mentioned is for everything in the station.
The KPA500 alone needs 120 volts at about 13 amps, maybe peaking to
something greater.

3000W at 120V is 25 amps. He had better have a dedicate circuit. I believe if
I had to run a dedicated circuit I would run a 220 circuit for the amp and put
everything else on the UPS.
