I bought a TYT TH-9800D Plus back in August to put in my car. It was my first one and I just wanted an inexpensive mobile unit to "get my feet wet" until such time I'd upgrade. Chirp has worked great up until a few weeks ago and now I'm getting these error messages. Same radio, same programming cable, same laptop (Toshiba Dynabook, Windows 11). The only difference, as far as I know, is a newer version of Chirp. But even going back and trying an older version of Chirp, I still get the same message.
This also appears to only be an issue with Chirp as the TYT and RT Systems software works fine.
I just wanted to toss this out there in case anyone else has seen it and found a solution.
