CHIRP

Until now it has been considered safe to upload the Main block of any Baofeng UV-5R style radio to another of a similar style. Only the uploading of the Aux block has been prevented when the firmware versions do not match.

It has been discovered that there is a "special block" in the Main block that differs between the High/Low power radios and the High/Mid/Low power radios (like the Intek KT-980HP or Baofeng BF-F8HP). Since these new radios with 3 power levels use the same ident string as the UV-5R style radios (with BFB291 firmware or newer), it is possible to upload the image from a radio having 3 power levels into a radio with 2 power levels. When this is done, the radio will no long receive any signals.

A patch is needed to prevent uploading an image file to a radio when the "special blocks" don't match.
