I didn't know anyone still used a CB. I haven't turned one on since I quit trucking. Even then I avoided 19. I used it to communicate with my escort vehicles, so we used a quiet channel. State police escorts would give me a handheld police radio set to go direct to their car, not to a repeater, so the range was short and would not interfere with other cops.
I knew a few ham operators, it seemed like they were vaccinated with a Victrola needle, because they never shut up, especially if we were traveling. Most had a personalized license plate with their call sign. As I remember, they liked two meter and ten meter. A couple had two meter repeaters set up at home. They also liked Cobra 29 Classic CB radios to convert to ten meter. I owned a store next to a truckstop, sold a lot of CB stuff. My tech would install the toys and tweak their radios. When I closed the business I had a huge box of K-40 whips, mirror mounts, and co-phase harness. I gave them to my son who was in high school and worked part time at a Blue Beacon. He sold them to truckers, installed them, and set the standing wave ratio. I think he made about two grand off that. And the guys were tickled pink with the price and install. lol I sure miss him, he was killed three years ago.
