@edegraaff I just checked the manual, and on page 3-3 in the Full Manual, it says to select USB mode, then click on Data, and it will change to USB-D / data mode.

Seems i found some issues with the configuration and one seems the Omnirig v1. I removed all software thad indirect influence the set. From there i reset the ic-7300 to defaults. Picket the FT*preset settings, and then started with WSJT-X and the mode indeed flippted to USB-D another new feature was the radio is working in split mode for sending and receving.
