Use a virtual serial port emulator (splitter) to split the COM port so HRD Rig Control and WSJT-X can control the radio. The USB cable is used for Rig control in WSJT-X. Same as #2, but close HRD rig control leaving HRD Logbook open. WSJT-X uses Ham Radio Deluxe as the Rig in it's settings. Get HRD up and running with the USB cable and using it for rig control in HRD. The USB cable for HRD rig control and the CI-V cable for WSJT-X rig control. Using two cables (it works well with other logging programs as well).Multiple ways to Integrate WSJT-X with Ham Radio Deluxe See my article Using the Icom 7300 with NEW Ham Radio Deluxe and WSJT-X. In this configuration I'm using QSO forwarding in HRD Logbook. I have videos and articles on WSJT-X and there are 3 or 4 good ways to integrate it with Ham Radio Deluxe. WSJT-X is also a very easy program to setup and operate, especially if you are using a radio like the Icom 7300 or Icom 7610 that has built-in sound capabilities. In the video below you'll see WSJT-X FT8. WSJT-X is a popular program for JT65, JT9 and the most popular mode is FT8. In this setup I'm using the CI-V cable for rig ( Icom 7300) control in WSJT-X as opposed to using Ham Radio Deluxe as the rig in WSJT-X. The last part of this series with Ham Radio Deluxe is adding WSJT-X FT8 to it.
