I'll give this a try. I would be a very simple fix if it works. Thanks.

Actually the BTech GMRS-V1 has semi-fixed channels. Channels 0 through
22 are fixed and channels 23 through 127 are programmable. I think the
driver may let the user go through the motions of programming the
fixed channels, the radio just ignores the changes.
