[Elecraft] Anyone else using a K3 with WSJT-X

[Bob]

Hey,

I have recently changed from JT65-HF to WSJT-X software.  I've had great
success with the software and its working well with one exception.  If I
enable bidirectional rig control (by setting a non-zero polling interval),
it works for a period of time -- however at some point, maybe 30 min, it
simply stops listening to the K3 anymore (commands sent TO the K3 work just
fine, but the VFO frequency is no longer shown).  This is most apparent
when I use the WSJT-X pull-down menu to change band.  The K3 changes band
as you would expect, but WSJT-X will continue to show the frequency from
the last band and it won't update, no matter how long you wait.

Its easy to restore operation by setting the polling value to zero (which
puts the WSJT-X software into a unidirectional mode -- control out, no
feedback in).  After setting it to zero, then putting it back to 2 seconds,
the ORG display will immediately update.  It will continue working properly
for a period of time, then fail in a similar fashion.

I don't suspect this is an issue with the K3 or cable, as changing the
WSJT-X setting seems to resolve things, so I suspect this is a issue with
the WSJT-X program itself.

Just wondering if anyone else is having a similar issue?
