Rugby Radio Station became the UK’s base for radio telephony and made the first transatlantic voice transition in January 1927 which was sent to Houlton, in Maine, in the United States.
It also sent the time signal, maritime and submarine communications and played key roles in World War Two.
It could broadcast a message so powerful that it would be picked up by almost every ship at sea.
After closing, part of the building that was used to house the transmitter was saved and developed into the school.
