I use CB for communication between one mobile and one base. I'm about to purchase an SSB radio for the base and for the mobile -- I've only used AM till now. If I'm only concerned with communicating with one specific base station, will I still need to constantly work the clarifier in my mobile as I drive? or will it stay locked in once I get it set good? I guess I'm wondering, does me driving around effect the frequency if I'm just communicating with one specific base station? I will be using the Galaxy CBs with SSB (base and mobile).
