Baofeng UV-5RV2+ Firmware N5R2407-BFB297 Programming Issue

I have several of these same model radios, but with different Firmware BFS313-BFS297. The CHIRP Programming works perfectly. I recently purchased several more of these same model radios, but with the newer Firmware N5R2407-BFB297. The only thing that does not seem to be programming correctly is the FM Radio Preset. The upload to the radio runs to completion with no errors. However, when pressing the Call button, the frequency of 65.000 is displayed. What was programmed is 89.300.

I have included my CHIRP Programming file.

  • Status changed from New to Rejected

On some of the new Baofeng radios, the radio no longer writes the frequency of the broadcast FM station to memory and no longer reads from it either. This is not a CHIRP issue. Sorry.

Updated by Jim Unroe about 4 years ago

After looking at the attached CHIRP Radio Image file, it appears to have been from a radio that was programmed with an image file that was a cross between a BFB memory layout and an N5R memory layout. This should not be. I would suggest that you upload a "factory" image to this radio to restore the memory to its proper layout for a radio with N5R2407 firmware.

This issue has been reopened. It appears that Baofeng has changed how they store the value of the broadcast FM radio frequency.

Downloaded CHIP Daily 20151225 and tried setting the FM broadcast frequency to 89.3. This worked on all six radios.
