[Elecraft] KX3 Computer Interface for digital modes

Even in DIGITAL MODE I would not trust anything *except* hardware PTT
(e.g. RTS to a transistor/optical isolator switch) preferably with an
external hardware time-out timer - particularly with computer based
operation.  I've had too many bad experiences with hanging and/or
mistimed software (command) PTT and VOX to use anything except hardware
based PTT.

On the other hand, prior to the K3 I had never found a VOX I could live
with.  I'm still so uncomfortable with VOX that I keep several of my
25+ year old old foot switches handy.

73,
