I just set mine up like yours using the K3 CAT
https://picasaweb.google.com/k5oai.sam/Digital#6013717488489012674
here's the sequence I use to make it work for me:
Set K3 to TX DATA DATA A
tune VFOA to say 14.076
double tap A>B (to set VFO A & B to all the same settings)
now HOLD A>B (to get into split)
now with WSJTX Configuration Station
[X] check enable CAT
Rig: Elecraft K3/KX3
CAT port: (set to your usb port)
Serial rate: 38400
Handshake: None
DTR and RTS boxes [ ] not checked
Data button
Data bits: 8
Stop bits: 2
[X] Split Tx checked
I use Polling interval (s): 5
click OK
(at this point you might want to exit and restart WSJTX to be sure the
setting were saved)
after restarting WSJTX
try clicking on some place in the watter rall and watch your VFO B move
around. this tells you it worked!
gud luck
