with an anti-American message. This action was followed on January 3, 1961, by a break in diplomatic relations between both countries that had been initiated by the US. Following this action, Cuba commenced broadcasting to the US and to the world, with a new international service called Radio Havana Cuba. In March 1961 Radio Swan announced that it would no longer sell its airtime for political programming and the station changed to an all-news format while infusing its broadcasts with coded messages. The station described itself as "assisting those who are fighting Castro within Cuba" and it began transmitting on fourteen frequencies. The CIA issued a press release claiming its anti-Castro broadcasts were now being beamed by seven radio stations as well as Radio Swan. A station identifying itself as Radio Swan briefly resumed broadcasts in 1975–1976 on 6.185 MHz. The station used a mailing address in San Pedro Sula, Honduras, and referred to itself as "La Primera Voz Democratica de Latinoamerica" ("The First Voice of Democracy in Latin America"). Since San Pedro Sula is located on the Honduran mainland, it is possible that these broadcasts originated there rather than on Swan Island, though no positive verification has been determined. Bay of Pigs invasion broadcasts During the Bay of Pigs Invasion of Cuba, which took place between April 15–19, 1961, it became obvious to all concerned that the purpose of the station was to assist in the landings. But following the abortive invasion, Radio Swan suddenly changed format again. While its tone remained anti-Castro, its programming did not promote an uprising against the Cuban government. The station changed its format and name and Vanguard Service Corporation became new owners of the station. Radio Swan became Radio Americas and it remained on the air until May 1968 when the station closed down and its AM transmitter was transported to South Vietnam to assist in the wars of South-East Asia. The World Tomorrow radio program One of the loyal sponsors who advertised on both Radio Swan and Radio Americas was Herbert W. Armstrong with The World Tomorrow radio program. In the January edition of his magazine The Plain Truth, a letter to the editor praised Armstrong by claiming that "... you could not have chosen a better station than Radio SWAN for reaching the Caribbean area. ... It is becoming popular with all those who share in the dislike of Fidel Castro
