Cold Springs Fire

[soundchaser]

I see some of these fire frequencies have a mode of FMN, I have most of them set for FM, should I change some of them to FMN? Will I hit them if it set for FM? 120's freq's I have them set for AM. I use a Pro-106, I hope what I wrote makes sense what I was wanting to know.

Leave the 120's set for AM. All Air to Air are AM and Air to Grounds (160's) are NFM. The "N" stands for narrow band.
