In 1927 the British government concluded that radio was such a powerful means of mass communication that it needed to be under state control, thus in 1927  they created a monopoly known as British Broadcasting Corporation (BBC).

The BBC was given government authority to raise revenue by charging a license fee to every home possessing a radio, and charged with the duty to provide programming . The UK population had no say in the type of programming the BBC was delivering.  By 1930 there were five million radio sets in Britain, all unavoidably tuned to the BBC.

Pop music on BBC radio was limited to short presentations of the music on weekends only and with straight laced announcers (no DJs).   Most of the British listeners turned to Radio Luxembourg, (*2) the only cross border broadcaster able to get back on the air after the war.  Radio Luxembourg  could only be heard at night in Britain when propagation was good. Despite the inconvenience the long signal fading periods,  Radio Luxembourg was extremely popular.  

In the 1960s the BBC enjoyed a statutory monopoly on radio in the UK. At that time the BBC broadcast little more than 2 hours per week of recorded popular music, a limit partly determined by the high level of royalties charged by record companies for airplay. From 1964 onwards,  a number of pirate radio stations started broadcasting from ships and coastal forts located around the UK,  but outside the 3 mile limit of British territorial waters. These pirate stations were not subject to British law in respect of both broadcasting rights and royalty payments. Most of them broadcast continuous recorded pop music and they funded themselves with advertising and sponsorship revenues  These stations were subsequently branded as “pirates”.   


Through the ensuing years the BBC and the British government were increasingly hostile toward any competition to their radio monopoly.  Their programming was limited mainly to programs aimed at boosting the morale of the British population.  This situation continued into the fifties when things began to change when the American Rock & Roll era  made it's way into the country.

In 1958 the first  European “pirate”  was Radio Mercur began  broadcasting from international waters. Established by a group of Danish businessmen the station transmitted  from a small ship anchored off Copenhagen, Denmark.

Radio Mercur's success  led to other groups starting similar ventures  including Radio Nord in 1960 anchored off Stockholm, Sweden.  Radio Veronica in 1960 began broadcasting in Dutch from an old light ship anchored off the Dutch coast. 

Caroline beginning

In the early sixties,  Ronan O'Rahilly,  the son of a well known and wealthy Irish family, came to London hoping to become involved in film making. Instead he got into the music scene managing new young artists. He quickly found out nobody would record his artists and nobody would give him air time because of government restrictions.




Radio Caroline & The British "Pirates"
1958-1970  (First Phase)
Radio Caroline DJ Johnnie Walker
O'Rahilly learned about stations the Voice of America was operating from ships at sea.  He gathered as much information on the operation from the U.S. Embassy.   He also visited Radio Nord and Radio Veronica gathering information regarding off-shore operations.

O'Rahilly then set out to fund the project.  While in the Dallas, Texas to buy transmitters he was reading an article in Life magazine and was captivated by a photograph showing president John F. Kennedy's daughter Caroline playing in the Oval Office of the White House and disrupting the serious business of government. This was exactly the image he wanted for his station. The name had to be Radio Caroline.

The original frequency  announced a wavelength of "199" meters (1509 kHz), which rhymed with "Caroline". In reality the station was on 197.3 meters (1520 kHz) at the low end of the medium wave band. The Dutch offshore station Radio Veronica was on 192 metres (1562 kHz) and when Radio Caroline was joined by Radio Atlanta and became Radio Caroline South, it chose 201 metres (1495 kHz).

The original transmitter power of the Caroline was almost 20,000 watts, which was  achieved by linking two 10-kW Continental broadcast transmitters together. Broadcasting hours were initially limited from 6 am to 6 pm daily under the slogan "Your all-day music station", because Radio Luxembourg came on the air in the English language at 6 pm and direct competition was avoided

With finance in place, Ronan purchased an old ferry boat named “Fredericia” which he promptly renamed “MV Caroline”and took it to the east coast port of Greenore, Ireland  for conversion.

Radio studios were built on the upper decks behind the ships bridge.  Power generators were installed in  the hold providing power for two 10 KW medium wave (AM ) broadcast transmitters.  The 165 ft. vertical antenna mast was installed on the deck near the bow of the ship.

Ronan was aware that  an Australian businessman,  Alan Crawford, was working on a similar project to place a broadcast station in International waters off the UK Coast which he was calling Project Atlanta. He was building his studios on a ship called  MV Mi Amigo. 

To ensure reasonable co-operation between the two projects Ronan and Crawford agreed Radio Caroline was to anchor in the Irish sea, broadcasting to Ireland, Scotland and the North of England while Radio Atlanta was to anchor off the  British coast at Essex from where it would cover London and the South East. 

Caroline was anchored three miles off the coast of Felixstowe, a seaside town on the North Sea coast of Suffolk, England.  It's 10,000 watt signal was a mere 80 miles from London and less from Luxembourg.

On Easter Sunday 1964  at 12 noon, Radio Caroline came on the air with the pre-recorded opening announcement “This is Radio Caroline on 199, your all day music station.”  Some of the first programs were recorded on land and taken out to the ship to be played as live.  Caroline was on the air shattering the monopolies of the BBC and Luxembourg and changing radio forever.

A month later, Crawford's “Radio Atlanta” was launched from the ship Mi Amigo,  located in international waters off the coast of Harwich, England. Both stations continued to operate completely independently for several months until merging operations months later.

Caroline then moved to an anchorage off the coast of the Isle of Man and broadcast as Radio Caroline North while the Mi Amigo remained off the coast of Essex broadcasting as Radio Caroline South. The British government classified both operations as  “pirates” though at that time, both were legally operating in international waters.

In 1966 the British Postmaster General, Anthony Wedgwood Benn, introduced a law that proclaimed the so called “pirate” stations illegal.  The law, called the “Marine Offences Act”, became effective on August 14, 1967 but  the two Radio Caroline ships continued to broadcast from international waters.  One of the first problems brought on by the new law was the daily boat that came out of Harwich with food, mail and other supplies couldn’t legally set sail.   Radio Caroline made arrangement to bring in supplied from Holland which could take 24 hours. Often the ship would run short of water.

The Act went after the main source of the station's income... advertisers.... by making it a criminal offense to assist in any way such stations by persons subject to UK laws.  

Station operators thought they could  get around the law if they were staffed, supplied and funded by non-British citizens, but this proved impractical.  Eventually,  unable to pay their bills,  particularly the company providing provisions,  Radio Caroline went off the air in 1968 when two tugs representing the supply company towed the vessels away to satisfy debts.

Footnotes:

(*) Not all the "pirate" stations were profitable, and in the early days, several smaller stations came and went - but the Big Six (Caroline South, Caroline North, Radio London, Radio 390, Radio Scotland and Radio 270) all made money for their backers.
__________________________________________________________________________________________________________________________________________

(*1)   According to WordiQ  (http://www.wordiq.com) the two ship stations of Radio Caroline International eventually ran out of money in early 1968 and a salvage company towed them away for unpaid bills. But when a new and very powerful offshore radio station aboard the MV Mebo II anchored off the coast of Southeast England in time for the British General Election, it suddenly switched its name from Radio Northsea International - (RNI), to - Radio Caroline and began to lobby for the introduction of licensed commercial radio in the United Kingdom. As a result of this development the British Government resorted to Jamming the station with a succession of increasingly powerful transmitters on the same frequency. After the election Radio Caroline fell silent once more and the radio ship moved back to Holland where it became Radio Northsea International once again.

In 1983 Radio Caroline returned to the airwaves from a larger ship called the MV Ross Revenge which had been previously used by Ross Fisheries as a fishing vessel in the Cod Wars with Iceland. The radio ship anchored off Southeast England and became home to: Radio Caroline in English with part time services known as Caroline Overdrive playing album music programs and Caroline Viewpoint airing sponsored religious programs. Also on board was a Dutch service on another AM frequency, which was managed under contract to Dutch organizations and known variously as: Radio Monique, Radio 558 and Radio 819. 1989, Dutch authorities with British assistance, raided the MV Ross Revenge and shut down all transmissions.

__________________________________________________________________________________________________________________________________________


(*2)   the 1960s in the UK, the term "Pirate Radio"  referred to not only a perceived theft of the state-run airwaves by the unlicensed broadcasters but also the risk-taking nature of offshore radio stations that actually operated on anchored ships or marine platforms. A good example of this kind of activity was Radio Luxembourg located in the Grand Duchy of Luxembourg. The English language evening broadcasts from Radio Luxembourg were intentionally beamed toward the British Isles by Luxembourg licensed transmitters, while the intended audience in the United Kingdom originally listened to their radio sets by permission of a Wireless License issued by the British General Post Office (GPO).

However, under terms of that Wireless License, it was an offense under the Wireless Telegraphy Act to listen to unauthorized broadcasts, which possibly included those transmitted by Radio Luxembourg. Therefore as far as the British authorities were concerned, Radio Luxembourg was a "pirate radio station" and British listeners to the station were breaking the law (although as the term 'unauthorized' was never properly defined it was somewhat of a legal grey area). This did not stop British newspapers from printing program schedules for the station, or a British weekly magazine aimed at teenage girls, "Fab 208" from promoting the deejays and their lifestyle (Radio Luxembourg's wavelength was 208 metres).

Radio Luxembourg was later joined by two other well known pirate stations received in the UK in violation of UK licensing, Radio Caroline and Radio London, both of which broadcast from vessels anchored outside of territorial limits and were therefore legitimate but unauthorized in much the same way as Luxembourg. Indeed, all three stations even had registered offices based in mainland UK.  (Courtesy of Wikipedia) .

Misc Quotes:

³ "When the seas were rough however, this proved to be somewhat of a problem, which I would guess was also true on some of the other pirate ships. We often had to weigh down the pick-up arms on the turntables, just to keep the needle from lifting out of the grooves of the records when the ship was rocking back and forth. To do this, we often used some of those monstrously large English (old) pennies, sometimes stacking up two or three of them at a time. It didn't always work however and sometimes the needle would literally fly off the records, which of course tended to mess up the songs that were playing at the time.

³ "We had a teleprinter which was supposed to bring us the news from the wire services. Sadly, affected by our transmitters, it generated only gobbledygook most of time. So it was back to the old tried and tested method of nicking the news from the Beeb."  (BBC) (Courtesy of The Pirate Radio Hall of Fame) www.offshoreradio.co.uk/sre1.htm

³ " Into this stifled arena came the “pirate” radio stations of the sixties. Although often referred to in the press as “illegal”, this was in fact journalistic laziness. Many of the stations would have been “illegal” if they had drifted another half mile landwards, coming under British law. They had been carefully planned, and were set up to be cunningly and carefully placed three and a half miles offshore where, outside the legal “three mile limit” of U.K. sovereignty they could safely ignore all national legal constraints.

³  (About Radio Caroloine)  "The RF combiner that allowed both of the 10KW transmitters to be run together to hopefully produce 20,000 watts of power. The transmitter room was on deck level, more or less below the studio where the two Continental Electronics transmitters stood side by side along with an audio compressor/limiter. The transmitters each contained a series of safety features which would cause them to shut down in the event of a problem. In very rough weather it was not uncommon for them to switch off, seldom both together, but the engineer would have to be on hand to push the reset button. I am not sure if this was due to the transmitters being tilted and tossed around or the effects of the waves breaking over the aerial upsetting the antenna tuning. The antenna was a folded dipole with a multiple wire forming one end and the steel mast as the other. The loading coils were in a purpose built cupboard in the ships lounge with heavy duty coaxial cable leading to the transmitters."  (Courtesy of

³ "But the end of Caroline was because of unpaid bills and NOT Government legislation remembers Don Allen. "It happened on a Saturday evening. We went off the air at ten o'clock and we watched a bit of television -- and about two o'clock Sunday morning, we were all set to go to bed when we heard this 'thump' on the side of of the ship. We all thought what could that be? Men from a tug had come across and had taken over the ship. They had pirated it. They said they had their orders to cut the anchor chain and late Sunday afternoon we were towed away."  (Courtesy of  Rock-it Radio's Tribute to Pirate Offshore Radio. www.rockitradio.net/pirate.html  )

³  "Not all the offshore stations were profitable, and in the early days, several smaller stations came and went - but the Big Six (Caroline South, Caroline North, Radio London, Radio 390, Radio Scotland and Radio 270) all made money for their backers.

³  The peak of the so-called "pirate radio" stations was only three years -- from 1964 until 1967 -- but in that time the freewheeling broadcasts, many staffed by Americans, brought a party atmosphere and a pop music variety to the UK  that had never experienced such a sound.

³  The British Government eventually forced the "pirate" broadcasters off the air in 1967.   They quickly  put a replacement for the pirates  on the air calling it "BBC Radio 1" . And it was based firmly on the program format created by the "pirates". It even employed mostly ex-pirate DJ's and used the same jingles.

³  A flotilla of nine ships and disused marine towers in the Thames estuary soon jumped on the floating bandwagon, and by 1968 boasted 10 to 15 million daily listeners. The Government had been monitoring the development of the industry closely. They decided it could not continue. Radio ships paid no taxes, no royalties on the records they played and their signals could be a hazard to shipping.   (Courtesy of http://www.suite101.com)
