The note I replied to claims the rules for CB have not changed, but they have. Sure, you don't need to grovel for permission; but there are plenty of other complications due to the addition of, and possible migration to, FM. Buying a CB radio is no longer a straight-forward process (if you plan on communicating with other CB users in your region).

I think I see. Can you elaborate on the complications and process? I am under the impression that something nearing 0-2 enforcement actions have been taken on CB operators in the last 30+ years. And these were for prolonged, amplified interference on popular channels (like 19) and only after several complaints were made and FCC warnings were ignored.
