CB RADIO FREQUENCIES AND CHANNELS

The CB Radio spectrum is broken up into 40 channels with CB frequencies ranging from 26.965 to 27.405 MHz. Channels are generally spaced 10 MHz apart. While these channels are open to everyone, some have commonly agreed upon purposes, which are noted in the table below. Examples include Channel 9 (reserved for emergency communications) and Channel 19, which is mostly used by truckers. If you want specific information or want to share messages on these channels, you are welcome to do so or just switch over for a listen. A fair warning though: truckers have their own handles and slang, and chatty visitors are not always welcome. So be prepared and know what you’re in for if you jump on 19 as an outsider.
