WSJT-X cat controls FT891 via DR891, but no Band activity is shown. It was working initially. Upon first install, band activity was working, but no cat control. Port is com3 and mode is USB.
Check that you get the audio coming in: there should be green bars next to Digirig’s recording device in the control panel.
Also the reason for no decodes can be something as simple as your computer’s clock being out of sync.
I installed the 2.7.0 release. No change. The PC clock is within .05 sec of correct time. The audio bar is green, showing between 40 and 80%. The Receiving bar in the lower left is green. The Decode button sometimes flashes.
Attachung screen shots.
Please share the screenshot of the waterfall screen after running the app for some time.
You can use “listen” feature to monitor the incoming audio via computer’s speakers and compare the audio with what comes from radio’s speakers.
Check that you followed all instructions for transceiver settings including setting WTH feature.
