What is CB?

Citizens Band radio (CB) is a 2-way voice communication system for personal use for the general public.  It lets you talk from your truck, car, home, business, or boat to other people who have a CB radio. Technically, a CB radio is a transceiver. It functions both as a radio transmitter (when sending messages) and a receiver (when receiving messages). Citizens Band radio was created by the FCC in 1958. There are as total of 40 channels on the CB band.  Channel 19 is unofficially regarded as a general-purpose channel to make contacts and listen to conversations and reports of traffic and road conditions.  Channel 9 is reserved for emergency communications.

Do I need a license to operate a CB?

No license is required.  The FCC used to issue licenses for CBs, but they discontinued that requirement many years ago.
