ICOM 7300 Won’t Stay In USB-D Mode on TX with WSJT-X or Z

Took forever to find this info but I found a post from Rich K0PIR on another website that resolves the problem.  This fixed my issue.

Hi Robert,Nice to hear from you.In WSJT-X under the Radio tab, set Mode to Data/Pkt and see if that helps.
