I recently bought 2 [GME TX677] UHFs, and I wanted a place to quickly
look up what each UHF channel is for, so here it is. I haven't used UHFs
regularly since the mid 90s, before the available channels were expanded
from 40 to 80.

Note: Duplex channels are repeater channels, generally with wider reach.
Check the [GME UHF FAQ] for more information.
