This is just a FYI from me.

Most radios have a minimum of 6 character display for memory.

Here is my naming convention.

Digits 1 and 2 are the county.

Digits 3 and 4 are the city.

Digit 5 is U(hf) or V(hf)

Digit 6 is Numeric 1-9 for instances of more multiple repeaters in a city.

When you have multiple dozens of repeater channels this quickly helps you see which is which.

Here are the first group of channels in my radio.
