The Ultimate CB Radio Page

Citizens’ band or short-distance CB radio was invented and first licensed in 1947 operating on a 27 megahertz (MHz) or 11-meter radio frequency over 40 channels. Military and other government entities originally used CBs to communicate until the 1960’s when taxis and other businesses began to use them. It’s range of use is around one to five miles.

CBs became mainstream when truckers began to use them to communicate with each other in the 1970s. Speed limits were lowered to 55 mph for safety and gas shortage reasons, often resulting in speed traps operated by law enforcement. Truckers would use CB radios to alert each other to slow down for police. CB communication also aided those in trouble. Channel 9 was designated the emergency station.

Today, truckers have digital gear to maintain communication such as GPS systems and cell phones, so CBs are mostly relegated to hobby status and neighborhood use in an emergency. No licensing is required.
