Re: [chirp_devel] [UV-5R] Support for 144/220 Model and Band Expansion

I believe the above is what you are referring to.

This is a BFB291 and newer (it is actually from a UV-5RAX BFB296 144/220 model)

0x0000-0x0007 AA 36 74 02 20 02 60 DD

36 = 136 MHz VHF lower band limit 74 = 174 MHz VHF upper band limit 02 20 = 220 UHF lower band limit 02 60 = 260 UHF upper band limit

Ah, right, okay. Too bad the OEM isn't a little more organized, huh? Grr.
