[Elecraft] KPA500 REMOTE POWER CONTROL

[Bob Wilson, N6TV]

KPA500 AUX Pin 12 is GND.  AUX Pin 8 is the KPA500 remote power ON/OFF
pin.  No webswitch is necessary to remotely power the KPA500 on and off,
since this can be done quite easily from a button on the K3 itself, using a
macro, as described here:
