I have had several individuals tell me that the UV-5R Settings tab does not work for them. The last person that reported the problem, I had convinced to switch from using v0.3.0 stable to 20130225 daily. I asked him to work his way back installing previous versions until the settings tap worked again and let me know what version it was.
He claims that the transition for a working to non-working settings tab occurs between CHIRP daily versions 20130216 (works) and 20130217 (doesn't work).
I'm trying to get a debug.log from this person.
Obviously, I am unable to duplicate this with my UV-5R radio with BFB231 firmware. This person has BFB281 firmware. I also have a similar issue with someone I have been trying to help me with the new Baofeng UV-5R 144/220 dual band radio.
