[Elecraft] K3: reverse 12 volt supply

[Richard Fjeld]

It was a passing thought as;  how to use a diode without causing a 
voltage drop was the original question.

AD5X has an OVP and Rev Polarity project on his website that would be 
better.

I couldn't think of the call sign at the time, so I suggested a relay.

(I've worked with huge contactors that were on motor-generators to 
prevent run-aways)
