[Elecraft] New KX3/WSJT-X puzzle

[David Haines]

That makes a lot of sense, Dave.  Two PTT types active at the same time 
is something that never occurred to me.  Except there's no PTT cable 
from the SignaLink, as far as I can tell.
But Greg AB7R suggested that I update WSJT-X, which seems to have fixed 
the problem.  I'm still puzzled as to why it started suddenly, after 
several months with no problem.
