Radio Veronica began transmitting in Dutch in April 1960 on AM mediumwave (192 meter, 1562 kHz; later 538 meter, 557 kHz) from the
MV Borkum Riff, and after 1965 from the
MV Norderney, in international waters off the coast of
Scheveningen, and soon became the most popular radio station in the Netherlands. Broadcasts were targeted to the Netherlands only, and transmitting power was deliberately kept moderate to avoid interference with international radio stations. Most broadcasts were recorded on shore in
Hilversum. The station operated until August 1974, when the Dutch ratification of the
Strasbourg treaty came into effect, after which Radio Veronica—then called VOO—became part of the regular Dutch broadcasting system. Radio Veronica is now an independent radio station. From 1964, Radio Noordzee and TV Noordzee transmitted in Dutch from
REM Island, an artificial construction resembling an early offshore oil platform. It was built in
Ireland and towed into a position off the coast of the Netherlands, where it was assembled on site. The two stations were short lived and were forcibly closed by an air and sea attack by the
Dutch Armed Forces. However, the funds solicited from the project by the REM island project were later used to launch a legitimate and fully licensed station in the Netherlands. In 1970,
Radio Noordzee Internationaal (RNI) began broadcasting on AM, FM and international shortwave from the
MV Mebo II, originally anchored off the Netherlands. The ship moved for some time off the coast of south-eastern England, where it was
jammed by a
Royal Navy transmitter, before returning to the Netherlands. The owners of the
MV Mebo II eventually sold their offshore station to
Libya as a revolutionary radio station. In the end Libya blew the vessel up and sank it for target practice. Other pirate stations broadcasting to the Netherlands included Capital Radio (1970, aboard the
MV King David),
Radio Delmare (1978, aboard the
MV Martina),
Radio Monique (1984-1987, aboard Radio Caroline's
MV Ross Revenge), and Radio 558/819 (1988-1989, aboard the
MV Ross Revenge). There are still many Dutch pirate radio stations, mostly located in rural areas. It has been claimed that in 2011 approximately 50% of all European pirate stations are located in the East-Netherlands, especially in the provinces of Overijssel, Friesland and Drenthe, as well as western Brabant. Most of the pirate radio stations broadcast so-called "pirate music": traditional Dutch folk music combined with classic English, German and Polka. Most operate on FM, but some can be found on AM, particularly 1611 to 1700 kHz. Like many other European countries, another hotspot is the 48 meter-band on
Shortwave radio, frequency 6200-6500 kHz. == Sweden ==
