Citizen Band (CB) radio is a type of two-way radio communication system that allows individuals to talk to each other over short distances. It operates on 40 designated channels within the 27 MHz band and does not require a license for personal use. CB radios are popular among truck drivers, outdoor enthusiasts, and hobbyists for their ease of use and ability to communicate without a phone or internet connection. CB radios can transmit voice messages and are often used for sharing information about road conditions, weather, and emergencies. They are equipped with features like microphones, speakers, and sometimes antennae to enhance communication range. CB radio has a unique culture, including the use of 10-codes and slang, making it a distinct form of communication.
