Having issues getting WSJT-X to work properly with Ham Radio Deluxe for rig control. Only one application can access a COM port at a time, so Ham Radio Deluxe Rig Control needs to be the application accessing the COM port. I keep getting frequency conflicts between the programs.

The rig must be set to 'Ham Radio Deluxe' in WSJT-X settings - the most common problem is setting it to the specific rig model instead. I'm running an IC-7610 and want to use both programs simultaneously for logging and digital modes. Should I launch Ham Radio Deluxe Rig Control and Logbook first to make sure both can see the rig?

Has anyone found a reliable setup procedure that prevents these conflicts?

Yes, absolutely start HRD first! Then launch WSJT-X and go to the Radio tab in Settings. Make sure you select 'Ham Radio Deluxe' from the rig dropdown, not your IC-7610 model. This routes all CAT commands through HRD's interface.

For PTT you can use VOX where the radio engages PTT when WSJT-X sends audio, or CAT where WSJT-X sends software commands through the HRD connection. I prefer CAT control as it's more reliable than VOX triggering.

Set the soundcard to the appropriate one for digital modes - soundcards can be shared by Windows applications, so it's fine to set it identically to how you configured it in DM-780. Once working, you'll see frequency changes in both programs.
