The strict definition of a pirate radio station is a station that operates from sovereign territory without a broadcasting license, or just beyond the territorial waters of a sovereign nation from on board a ship or other marine structure with the intention of broadcasting to that nation without obtaining a broadcasting license from that nation (such as Radio Caroline before its present incarnation). Cuba Pirate radio by Cuban exiles Unlike the sanctioned and fully licensed transmissions by the United States government, a number of groups in exile, mainly based in Florida, have attempted various offshore radio broadcasts to Cuba, from time to time. These stations are mainly short lived and sporadic in transmission times, but because their broadcasts are not licensed by any nation, their signals are considered to be from pirate radio stations and the USA has taken various physical and legal steps to close them down at different times. However, when the USA government broadcasts to Cuba within the medium wave broadcast band, such operation violates certain agreements to which the USA government is a party. Mexico Pirate radio in Mexico There are a number of pirate radio stations in Mexico. Radio Insurgente, the voice of the Zapatista movement, operated from 2003 to 2009. The station was unlicensed, but according to the San Andres Accords, the indigenous communities targeted by Radio Insurgente had the right to broadcast their own content. The most recent example of a true pirate radio station in Mexico is La Tremenda 106.5 in Nuevo Laredo, Tamaulipas. It broadcast international contemporary music and news in Spanish and English. It used the fictitious U.S. call sign "KLPR" on its logo. The station began operations in May 2006, was shut down in June 2008 by the federal police in a "violent" take over. It was suspected that the signal was also used for transmitting messages of members of organized crime. Today, there are several other pirate stations in Nuevo Laredo as well. The border-blaster or other border stations in Mexico do not meet either above definitions of pirate radio station, however may be considered as such by some governments. Border blasters From the earliest days of the history of broadcasting, a number of radio stations licensed in Mexico, became known to the general public as border-blasters. This was due to their excessive use of power which was necessary to reach their intended audience in American cities far
