Description

On my new UV-5R, the CHIRP-entered frequency for the FM radio gets uploaded to the radio, but upon using the radio afterwards doesn't work (appears as if write failed). I've diagnosed this to a big/little endian issue (byte reversal) between CHIRP and the UV-5R. CHIRP is big endian, UV-5R is little endian (for FM radio frequency anyway).

I did hex dumps of CHIRP img files to compare the memory contents for values stored by CHIRP (for upload) versus contents for values stored by the UV-5R (via download). Attached is a cut-n-paste of hex dump data of img files for two test cases I did.

This issue appears in other bug reports, including 2299, 2765, and 10005.
