Severe weather, EMP, solar flares, terrorist attack, or governmental collapse could cause an emergency situation where your cell phone and internet no longer work. Having a Citizen Band radio (CB) can help you stay up to date on the latest happenings because you can both receive critical bulletins and request assistance if need be.

CB radios will likely still function after an EMP scenario. The likelihood increases if they are stored in a Faraday cage and have an alternative power source, like batteries, which also have been safely stored.
What is a CB Radio?
A CB radio is a citizens band radio. It is a land mobile system that allows short-distance voice communication between individuals. They have a range from three to twenty miles, although some conditions will allow for intermittent communication over a much larger distance. Most countries do not require a license for you to operate one.
Why is it Important to Learn CB Codes?
Because only one person can transmit on a frequency channel at a time, using a standard language streamlines communication. Whether you are using a vehicle-mounted, base station with external antenna, or handheld CB, the communication codes are the same.
For preppers, having access to communication in various forms is a powerful tool for you and your family’s readiness. You need to know how to speak and understand the language being used, however.

Break or breaker, followed by a number, lets other users know that you want to start transmission on a specific channel. So, for instance, Breaker one-five would refer to channel 15.

If your technique needs a little work, you might hear 10-91 (talk close to the mic) or 10-92 (your transmitter needs adjustment). 10-11 means you are talking too quickly.

Respecting air time and other users are vital to successful CB use. Because only one person can speak at a time, you’ll need to be careful you aren’t interrupting an ongoing conversation when you break in. This is also referred to as stepping on or walking over. When more than one user tries to use the same channel, no one can be understood.
