[Elecraft] Keying CW in SSB Mode [explained]

[Ed K1EP]

Wayne, I have used this feature in the past with success and like it on 6M.
However, we recently switched to a setup where we need to sequence the amp
and relays, making the use of PTT (foot switch) mandatory. I turned off VOX
and breakin, but hitting the paddle in this mode still acts like VOX is
enabled and runs the risk of hot switching relays. Is it possible to make
that PTT TX too?
