PROS (like SOLAR) includes channels you probably already have in your scanner if you're listening to any of the agencies listed in the title. Examples: CNF, FIRE OC (Orange Co), RRU2, VFIREs, the 3 SoCal CalFire Commands, and Federal Air-Grounds. As you can see, if you're programming initial attack wildland channels from San Diego Co, Riverside, and Orange, you already have them.
