US and Canadian Channels

The CB radio channels are radio frequencies reserved for the use of the CB.

 

In the US and Canada, the CB radio frequency band is located between 26.965 MHz and 27.405 MHz, as is often the case in other countries. It is divided into 40 channels spaced 10kHz from each other, and numbered from 1 to 40. The 40 channels cover the entire frequency band allocated to the CB and are used for general communications, allowing users to chat with each other on a variety of topics.

 

It is important to respect the codes of conduct and communication protocols when using these channels, to avoid interference and disruption with the other users. Please see the Legislation section for more information about accepted standards of conduct while using CB radios.

 

Channel 9: This is the Emergency channel and cannot be used for any non-emergency situations.

Channel 19: This is the priority channel used by truckers to exchange driving conditions on highways and major roads. This channel must not be used for casual conversations and should be left open for important road and weather conditions.

Other channels: These are the free and open channels that can be used by anyone. Channels 16, 37, 38, 39 and 40 are also open to SSB communication.

Other operators, including the military and other federal agencies, use frequencies outside of the CB radio legal frequency range. We recommend not to use the frequencies outside of the ones described above. To do so would invite the FCC to knock on your door. Please check out the FCC Website for more information.
