I have a TYT TH-UV3R. When I download my channels from my radio to CHIRP, CHIRP changes some, but not all, of the offsets.
I first enter the frequencies into CHIRP and upload them to my radio. I check my radio and the offsets are correct. Then I download the frequencies back into CHIRP and see that the offsets have changed. If I were to re-upload them to my radio, then the wrong offsets would be uploaded. So anytime I need to add a channel, I need to redo all the changed offsets.
As I mentioned, not all offsets are changed, but the ones that do change change whenever I download my channels to CHIRP.
Are the offsets actually changing, or just formatted differently? Many radios can't differentiate a split from an offset, so what gets programmed as split 145.000 MHz rx, 146.000 MHz tx, will download back to Chirp as 145.000 MHz + 1 MHz offset. These are equivalent and don't require redoing before uploading.
If the offsets are actually different, it sounds like a bug. Create a new issue and attach the bad .img you downloaded, a fixed .img like what you upload, and a description of what the channel data is supposed to contain.
