[Elecraft] KX3 Power On and AM

[Phil Genera]

You could also build something to apply power to the PTT line and turn it
on:
"To turn the KX3 on, a remote-control system can place 8 to 12 volts DC on
the mic jack’s PTT line for 100 ms or longer."

kx3 owner's manual, revision c2, page 28. Power off would still be two
buttons, or require a CAT command.
