Thanks @Sshannon, that makes perfect sense. I like the fact that those are available for a trip. Obviously much better than pulling over and digging out the laptop.
In the programming software for the Baofeng MP31 radio it shows the normal channels 1-22, the repeater channels 23-30, and then 31-38 which appear to be duplicates of 23-30.
Anyone know what these channels are? They have the exact same frequencies as 23-30.
Thanks,
Terry
