I have commander, and wsjtx working with flex but changing freq on one wsjtx ends up changing both instances. I unchecked SPLIT before starting wsjtx but trying to change freq activates split in commander which is probably why both slices change to the same band.
+ The "Installing and Configuring Additional WSJT-X Instances" section of
+ explains how to configure multiple instances of WJST-X when using the direct form of interoperation between DXLab and WSJT-X. I don't know how that's done with JTAlert, which is why I referred you to the JTAlert support group.
