[Elecraft] KPA500 Power Switches

Rates vary widely around the country. Here on the Central Oregon Coast we
are supplied by the Bonneville Power through 31 dams, over 2,350 wind
turbines and a nuclear power plant. We pay 6.31 cents per kilowatt hour.

Some power is bought off of the grid at peak times, so our power overall is
only 93% carbon-free.

I wish that were true. But I'm paying a peak rate of $0.34 per kWh, and we
do lots of things to minimize our power use in that penalty area.  
Indeed, one of my mental cost justifications for buying the KPA500 was that
its instant-on feature saved the cost of keeping the filaments of my Titan
going when I was in the shack. So I really would like that front panel
switch to kill power to the unit, not just to the microprocessor.
