It was clearly the Kenwood TH-41 model. They had different colored rings
around the top of the antenna for the different bands. UHF was green.

Wrong.
GMRS is Class A CB (FCC designation) while the 27 MHz band is Class D
CB. I don't recall what classes B and C were offhand. FRS didn't exist
until recently and has never carried an official CB label even though it
too is under Part 95. MURS is even more recent.
Both Class A and Class D
Class B was something on UHF, and class C was 27 MHz remote control.

Does anyone have any info on the old class B CB? I'm thinking it was
a single simplex channel on 465.000 and 5 watts. May have been
another frequency. Could have been AM too. I remember seeing an old

Class B was the old day equivalent of FRS, Class C is the Class D
