Radio Caroline is a British radio station founded in 1964 by Ronan O’Rahilly and Allan Crawford, initially to circumvent the record companies’ control of popular music broadcasting in the United Kingdom and the BBC‘s radio broadcasting monopoly.^[1] Unlicensed by any government for most of its early life, it was a pirate radio station that never became illegal as such due to operating outside any national jurisdiction, although after the Marine, &c., Broadcasting (Offences) Act 1967 it became illegal for a British subject to associate with it.

The Radio Caroline name was used to broadcast from international waters, using five different ships with three different owners, from 1964 to 1990, and via satellite from 1998 to 2013. Since August 2000, Radio Caroline has also broadcast 24 hours a day via the internet and by the occasional restricted service licence. Currently, the station broadcasts on 648 kHz AM across much of England and DAB radio in certain areas of the UK: these services are part of the Ofcom small-scale DAB+ trials. Caroline can be heard on DAB+ in Aldershot, Birmingham, Cambridge, Brighton, Glasgow, Norwich, London,^[2] Portsmouth, Poulton-le-Fylde and
