What is a CB radio?
A CB radio, also known as a Citizen Band radio, is a communication device that uses the CB radio bands to allow wireless communication over short distances. CB radios are usually easy to use and do not require any special licensing or training.
History of CB radios
The history of CB radios dates back to the 1940s when they were first introduced in the US. Originally designed for use by community radios, CB radios quickly became a popular means of communication for truck drivers, outdoors enthusiasts and others who wanted an easy and inexpensive way to communicate.
How does a CB radio work?
CB radios operate in the frequency range from 26.565 to 27.405 MHz and utilise AM, FM and SSB modulation modes. They use an antenna to transmit and receive electromagnetic signals. Communication takes place via different channels on which people can talk to each other, similar to a walkie-talkie.
CB radios and their applications
CB radios are used in various applications. Truck drivers use them to communicate with each other and exchange information about road conditions, traffic jams and rest areas. Outdoor enthusiasts use CB radios to stay in touch during activities such as camping, hiking or off-road driving. CB radios are also used by security personnel, construction site operators and event organisers.
