Why didn't I do this before. In Oct 2021 I rebuilt my Pi-Star with Pi Zero 2, including Pi-Star from scratch. Around this time my FT-991A stopped talking to YSF/C4FM. Well tonight, I decided to reset radio. A few minutes of adding settings and it works. #hamradio
I had to sort some setting for my Raspberry Pi and WSJT-X. Had no audio out, but found was SSB Port Select (wasn't USB) that was wrong.
