Dan,
If I understand what you are getting at, that changed with BFB291

This is my BFB231

0x0000 to 0x0007
AA 42 46 42 32 33 31 DD

42 = B
46 = F
42 = B
32 = 2
33 = 3
32 = 1

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

These values change based on the OEM software band limits set in the Other
menu.

CHIRP should probably change them as well. I've been thinking about it but
I haven't been smart enough to figure it out how to do it yet (I had been
considering putting out a request for help).
