This was unacceptable to the CB lobby partly because the low power would give a short range but mainly because the cost of equipment to operate in this band would be prohibitive. The government initially proposed an FM system on a 928В MHz band with an RF input power not exceeding 500В mW. Many active and potential users continued in their insistence on a 27В MHz system, although for a locally available Citizen's Band system, the 27В MHz concept was not universally endorsed. The CB lobby argued that interference from AM was unlikely to occur from the use of original unmodified AM radio equipment, a view initially rejected but later accepted by the Ministry of Defence. Interference problems associated with badly calibrated amplitude modulated (AM) or Single Side Band (SSB) equipment were cited as the main factor, and it was made clear that if any system was legalised it would be frequency modulated (FM).

The UK government made it clear from the outset that legislation for use of this equipment would be unlikely. In the early stages of the run up to the final legislation, most of the pro-CB lobby wanted the government to legislate around the US standard CB system, primarily due to the large user base that already existed. As of 8 December 2006, a licence is no longer required to own or operate a CB radio providing it complies with one of the 3 type approval conditions currently permitted by Ofcom: FM only, 4 watts power output and operating on either or both UK and CEPT (EU) 27В MHz bands only. Unlike that required to qualify for a radio amateur licence, no proof of technical competence was needed. A licence to operate these new radios became compulsory, and this could be purchased from most Post Office counters for ВЈ15. Given that virtually all illegal CB radios were contraband, this concession required the licensed amateur to pay outstanding import duty and VAT. At the same time the ownership of non-UK approved 27В MHz transceivers was made illegal except for those obtained by UK radio amateurs holding a UK 'A' (HF) licence, for conversion to the 28В MHz (10-metre) amateur allocation. The UK Government eventually legalised CB radio, and on 2 November 1981 a CB service was introduced on a frequency band and offset that is incompatible with the imported American radios. Many expensive models were written off, and the safety implications were obvious, but there was no practical way to police a separation, and the government did not rate the protection of model flying as an important issue.

They were paying for a licence to use the band, and interference resulted in loss of control of the aircraft. The big problem for the UK was that the 27 MHz band was already licensed legally to radio control model aircraft users. In response to this, the government commissioned a white paper proposing a CB service called 'Open Channel' around 860В MHz. During this time, a great many CB clubs emerged in the UK and they became centres of protest in the march towards legalisation, in the hope that existing equipment could be used legally. Companies in Britain sold US equipment quite openly, and equipment was readily available in car accessory shops.

In the period 1976вЂ“1978, CB radio in Britain was much popularised by novelty hit songs and its use in the film Convoy and the usage of illegal CB radio peaked in 1980. As citizens band radio has been advertised in the US since before 1962, it is possible that a number of these radios were brought into the UK and used illegally. Early use was known around the international shipping ports in the UK, particularly Liverpool, London and Southampton in 1968.

9 Licence-free CB brings rise in popularityД¬B radio was first introduced into the United Kingdom around 1968.

It is also fitted as standard to 'Street Glide' and 'Electra Glide' models of Harley Davidson touring motorcycles sold in the UK. Although the use of CB radios in the UK has declined from its peak, it is still popular, especially with the farming community, Land Rover owners and Mini-Cab services. In December 2006, CB radio was deregulated by Ofcom and it is now licence-free. In the United Kingdom, CB radio was first legally introduced in 1981, but had been used illegally for some years prior to that.
