K3 "KEY OUT" to Alpha "RELAY". That's all (apart from RF, of course!).
Some may recommend using ALC, but it should only be as an overdrive
protection mechanism, if used at all. Keep the drive level down so the
Alpha is operating within (mainly grid-current) specs, and all will be
well.

Connecting of Alpha KEY OUT to K3 TX INHIBIT is a good practice too. A
pull-down or pull-up resistor might be needed.
