I just bought a 2nd UV-82, and CHIRP reads it but will not display any data, if I try to write to it I get a unsupported version error.I have another UV-82 that works perfectly with CHIRP.Checking the radios I see the following firmwares#1 - BF8210 (works with CHIRP)#2 - B82S21 (Does not work with CHIRP)any ideas?
