I used to keep a CB radio mounted in all of my vehicles, but since I got my truck in 2000 and a cell phone shortly after, I have not bothered. But the Kim family's ordeal convinced me to permanently add some sort of 2 way radio to my vehicle kit. I have an older Motorola Distance DPS 2W radio that I am going to start carrying along with the car charger. Aside from redundancy, would there be any advantage to also mounting a CB? Also, is there a dedicated emergency channel for FRS/GMRS radios (like Channel 9 for CB's?)
