Bob,

 

Although running this sort of split will work on some rigs using CAT control, by selecting "Settings->Radio->Split Operating->None", it is not officially supported.

If it doesn't work for your rig, then you can disable CAT control and set the rig's VFOs and SPLIT manually by selecting "Settings->Radio->Rig->None". This clearly cannot be used with CAT PTT commands but if your rig supports PTT via RTS use that, or VOX (or DATA VOX) on the rig.

You can make a separate configuration in WSJT-X to support this including the Rx the frequency for logging.

I hope this is of assistance to others.
