[Elecraft] WSJT-X K3/K3s hanging as Tx

[Matt NQ6N]

I'd experienced this problem, also not due to RF in the shack, and since I
switched to using PTT via RTS or DTR the problem has not recurred.  The
problem began when I had been using RCForb and a virtual serial port with
CAT control of PTT for WSJT-X, so the explanation Joe offers makes sense
based on my experience.

Unless WSJT-X had some provision for reviewing all state changes to the K3
that might occur "unexpectedly" due to other CAT "clients" of the K3, it
would not be able to guarantee that its own state matched that of the K3,
which could seemingly result in the sort of behavior being experienced.

73,
