The Complete History Of CB Radio 1945-1981
Ringway Manchester・10 minutes read
Al Gross, an engineer from Parsons People Electric Products, significantly contributed to the development of Citizens Band (CB) radio, which became popular in the U.S. in 1945 and was notably used by truckers for communication and security. The legalization of CB radio in the UK in 1981 came after extensive lobbying but faced mixed reactions due to licensing costs and restrictions, ultimately leading to a decline in its usage as mobile phones gained prevalence.
Insights
- Al Gross was instrumental in the development of Citizens Band (CB) radio, which evolved from military two-way radios used during World War II and was significantly improved by the introduction of transistors, making the technology more accessible and affordable for the public.
- The establishment of the Citizens Band Radio Service in the U.S. in 1945 allowed various groups, especially truck drivers and tradesmen, to utilize CB radios for communication and safety, leading to a vibrant culture that included CB clubs and a unique language, although the subsequent legalization of CB radio in the UK in 1981 faced challenges due to regulatory restrictions and the rise of mobile phones.

What is Citizens Band radio?
Citizens Band (CB) radio is a two-way radio communication system that allows individuals to communicate over short distances using designated radio frequencies. Established in the United States in 1945, CB radio operates primarily in the 27 megahertz band and was initially designed for use by tradesmen, truck drivers, and hobbyists. The system features a 23-channel setup, enabling users to connect with one another for various purposes, including entertainment, safety, and information sharing. Over the years, CB radio has evolved significantly, particularly with the introduction of solid-state electronics, which made the devices smaller, lighter, and more affordable, thus broadening their accessibility to the general public.
How does CB radio work?
CB radio operates by transmitting and receiving radio waves over specific frequencies designated for Citizens Band communication. Users can communicate with one another by selecting a channel within the 27 megahertz band, which allows for short-range conversations. The technology relies on radio transceivers, which combine both transmitter and receiver functions, enabling users to send and receive messages. The introduction of solid-state electronics has improved the efficiency and reliability of these devices, making them easier to use and more portable. CB radio users often employ a unique language, including ten-codes, to facilitate communication, particularly in noisy environments like trucks or construction sites.
Who uses CB radio today?
Today, CB radio is utilized by a diverse group of individuals, including truck drivers, outdoor enthusiasts, and hobbyists. Truckers were among the first significant users of CB radio, relying on it for communication regarding road conditions, fuel availability, and safety alerts. While the popularity of CB radio has declined with the rise of mobile phones and other communication technologies, it still serves as a valuable tool for those in remote areas or for specific communities that prefer its use for real-time communication. Additionally, CB radio clubs continue to exist, fostering a sense of community among users who share a passion for radio communication.
What are the benefits of using CB radio?
The benefits of using CB radio include immediate communication without the need for a cellular network, making it particularly useful in remote areas or during emergencies. CB radio allows users to connect with others in real-time, providing vital information about road conditions, weather updates, and safety alerts. It also fosters a sense of community among users, as many participate in CB clubs and share a common interest in radio communication. Furthermore, CB radio is relatively inexpensive compared to other communication devices, and the lack of monthly fees makes it an attractive option for those who need reliable communication without ongoing costs.
Is CB radio legal in the UK?
Yes, CB radio is legal in the UK, having been officially legalized on November 2, 1981, after significant lobbying efforts. The British government updated regulations to allow the use of FM equipment on designated frequencies, specifically 27 and 934 megahertz. However, the legalization came with certain restrictions, such as limitations on antenna choices and the requirement for a license, which may have contributed to a decline in operator numbers over the years. Despite the regulations, some users continued to operate illegal equipment, reflecting the ongoing popularity and demand for CB radio communication among certain groups.

The Evolution and Impact of CB Radio
- Al Gross, an engineer from Parsons People Electric Products in Cleveland, Ohio, played a pivotal role in the development of Citizens Band (CB) radio, which evolved from portable two-way radios used by the U.S. Army during World War II, significantly enhanced by the introduction of transistors.
- The Citizens Band Radio Service was established in the United States in 1945, regulated by the FCC, initially operating in the 460 to 470 megahertz UHF band, with a 23-channel system set at 27 megahertz in the 1960s, primarily benefiting tradesmen, truck drivers, and electronics hobbyists.
- The introduction of solid-state electronics reduced the size, weight, and cost of CB radios, making them accessible to the general public, leading to the formation of CB clubs and the development of a unique CB language alongside ten-codes.
- The first significant users of CB radio were American truckers, who utilized it for entertainment and as a security measure against hijacking, especially during the oil crisis when they needed to locate fuel stations, while also serving as a communication tool for isolated communities.
- In Britain, the government updated the 1949 Wireless Telegraphy Act to regulate CB equipment due to concerns over illegal usage, leading to the formation of the Citizens Band Association, which campaigned for frequency allocation on 232 megahertz, but was met with impractical government proposals.
- By 1981, the British government announced the legalization of CB radio, allowing FM equipment on 27 and 934 megahertz, following significant lobbying efforts, although many users continued to operate illegal AM and sideband equipment despite the new regulations.
- The legalization of CB radio in the UK on November 2, 1981, was met with mixed reactions, as the £10 license allowed operation of three CB sets but imposed restrictions on antenna choices, leading to a decline in operator numbers as mobile phones emerged in the following years.
