UK CB (Citizen Band) Radio Frequencies:

USA CB Bands Were widely pirated in the UK in the late 70's to early 80's until legalised on an entirely different set of Frequencies and using Narrow FM (called: CB27/81), You might still find the odd user still on these frequencies but probably using SSB (Single Side Band) for DX'ing around the world. After much pressure the Government reluctantly allocated the Band to the UK but decided to keep the NFM mode instead of the AM mode that the USA used. Update: - 2015 It Is Now Legal To Use AM & Sideband (USB/LSB) On Both UK Band Allocations, But It Is Still Illegal To Do So On CB Radios That Do Not Confirm To British Standards, That Means You Still Cannot Legally Use Your Old Americn CB Radios.

UK CB27/81: 40 Channels FM, maximum of 4 watts, First Allocated CB Band in the UK.
UK CEPT: 40 Channels FM.
934 UK: 20 Channels, maximum of 8 watts output and 8 element beam. withdrawn from CB use on 31 December 1998.
