[Elecraft] K3 and JT65/WSPR

Use DATA A - set audio input to Line IN once you have selected DATA A,
then adjust VOX gain to trip when the JT65 audio is being generated.

You will have better results if you use a serial port or USB to serial
converter with a single transistor driver on the RTS line for PTT as
teh JT65 software switches the transmitter "on" one second before the
tones start to avoid clipping the initial tones or hot switching any
amplifier/preamplifier relays.
