New 80 channels

[GME Man]

Hello there, I am upgrading my radio from the additional 40 channels to 80 channels. I was just double checking, do I select channels 41-80 as narrow band and leave the original 40 channels as wide band or do I select all channels 1-80 as narrow band.

Thanks.

There is mountains of information relating to this all over the Internet, including on this very site. I'm not going to go in depth, however basically:
- all channels are 12.5khz, except 22/23 which are 25khz (but these channels can only be used for permitted data).
- channels 61/62/63 do not exist and should not be programmed (they are set aside due to the above data channels).

Thank you peteramjet
