For me, I read the radio forums avidly - it's amazingly divisive, and some of it illegal. CB has settled down nicely in the main to a community. The PMR446 folk can't do much with the low power they are allowed and no proper antenna rules - so they buy (sometimes from me) higher power radios that I know they will put on the low power unregulated band and talk for miles. Ethically, I'm torn. It's wrong, but I sort of have to set that to one side. CBers and PMR446 folk even have a sort of national database of callsigns, it's highly organised into communities. They of course hate the hams, and the hams hate them - many secretly are both. Old hams hate new hams, because the tests they took were different/easier/harder, and many continue with Morse, which puts those people into a promoted/demoted category. I sell one radio that is designed for radio hams, but can be used by CB'ers - that's always fun when people order them and ask advice. I have two different answers, depending on who asks. What is clear is people like the idea of these communities. The technology is crazily complex for some, simple for others. I programmed one radio for an elderly chap to talk to his elderly friend ten miles away. I messed up, but he won't let me fix it. His first response when he called was from a trucker on the old Route 66 in America. He has kept my programming error. He is 85, and enjoying his new unexpected hobby.
