Citizen Band Radio (CB Radio) is a two-way radio system that allows individuals to communicate over short distances. It operates on 40 designated channels within the 27 MHz band and is commonly used for personal, business, and recreational communication. CB radios are popular among truck drivers, outdoor enthusiasts, and hobbyists. Users do not need a license to operate CB radios, making them accessible to the general public. Communication is typically limited to a few miles, depending on terrain and conditions. CB radios can be used for various purposes, including emergency communication and sharing information about road conditions.
