In 1964, the Radio Society of Great Britain (RSGB) initiated the Islands on the Air (IOTA) program, designed to stimulate interest in contacting and activating island locations worldwide. IOTA encourages amateur radio operators to venture to remote islands and make radio contacts, promoting DXpeditions and fostering a spirit of adventure and exploration. Participants earn awards by contacting a specified number of islands, each with a unique IOTA reference number. The program has become immensely popular within the amateur radio community, highlighting geographic diversity and the technical challenges of island operations, and enhancing global communication and camaraderie among operators.
