Success! I reinstalled HamLib. I went to Preferences - Add/Remove Software and did a search on HamLib. I clicked on all the choices with the exception of SoapySDR. Now I call up a terminal on the DSI screen, cd to sbitx directory, start ./sbitx, close out Fldigi, start WSJT-X and move it to the HDMI monitor screen, and the WSJT-X now connects for rig control. l log in through the 8080 weblink on a third monitor on another computer and? I can change frequency by web control, and the frequency changes register appropriately back on the WSJT-X HDMI window from the rig. And I just completed a FT8 QSO to Texas, so it works.
