I have a 991a with a bad USB interface. I am using the RS232 and data ports with digi rig. WSJT-X I have cat and ptt working.
ISSUE:
I only hear and see data when mode is set to USB. When I set mode to DATA-USB I do not hear or see any activity. Again in USB Mode, I am hearing data and seeing it on the waterfall as well as in the band activity.
Any suggestions?
