Quick Answer
CB radios can be used legally without a license in the United States, as long as you follow the Federal Communications Commission (FCC) guidelines.
CB Radio Frequency Allocation
CB radios operate on a specific frequency band, 26.965 MHz to 27.235 MHz, which is allocated for public use without a license. This band is divided into 40 channels, each with a 10 kHz bandwidth. The FCC regulates the use of these frequencies to prevent interference and ensure public safety.
CB Radio Technical Requirements
To use a CB radio legally, you must ensure it complies with FCC technical requirements. This includes a maximum power output of 4 watts, a channel selector, and a modulation system that meets FCC standards. Your CB radio must also be certified by the FCC and have a label indicating its compliance with regulations. You can verify your radio’s certification by checking the FCC ID number, which is usually printed on the radio’s label.
CB Radio Operating Guidelines
When using a CB radio without a license, you must follow FCC guidelines for operation. This includes keeping transmissions brief and informative, avoiding the use of profanity or obscene language, and not transmitting interfering signals. You should also be aware of the FCC’s regulations regarding tone alarms, which are prohibited on CB radios.
