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.

These channels are for Australia, other countries may be different.
