I remember sitting in my grandparents kitchen in Southern Oklahoma and talking on their big Cobra base station. They had side band and an extra amplifier on their unit...which broadcast from a 40' tower from their house which sat on top of a 200" hill. To say they could talk to anyone anywhere was an understatement.
I just remember the early 23 channel units having a lot more power to reach out and touch people several states away than the 40 channel units.
And any CB is still better than a Fuzz Buster any day of the week.
Yeah, these folks would run the coax to the ridge and mount an antenna up there, with at least one amp in the setup.
In Virginia, even then, a fuzzbuster could get you busted, and they're still illegal out there.
Radio could help in a pinch, was used to report fires/accidents, jibber jabber (ratchet jaw), road conditions (route semi-traffic going into construction areas) and the like, it was just a whole lot more useful. The early ones did seem more powerful, and there were guys with linear amps out there who came through better'n broadcast.
