Hi: I have the setup working. Check screen captures. Cat and Freq control IC9700. Not sure if OMni still required but sharing setings anyway. Please note that you can define NONE in Freq Control and change freqs manually until you figure out setup. In my case I have freq control through IC9700.
Sometimes the -DUP get enabled and I disable using the IC9700 FUNC button. Still waiting for a local to test QSO, Chat functionality, Broadcasting and everything else!!
