Radio London, also known as
Big L and
Wonderful Radio London, was a
top 40 (in London's case, the "
Fab 40") offshore commercial station that operated from 23 December 1964 to 14 August 1967, from a ship anchored in the
North Sea, three and a half miles off
Frinton-on-Sea,
Essex, England. The station, like other
offshore radio operators, was dubbed a
pirate radio station. Its offices were in the
West End of London at
17 Curzon Street, just off
Park Lane.
