Standing on the summit is the North Hessary Tor transmitting station, an FM radio and television transmitter which uses a {{convert|196|m|ft|0}} high guyed mast. It was built by the BBC in 1955 when a transmitter was needed to introduce 405-line television into Devon. It now carries a small UHF TV transmitter which serves Princetown and Dartmoor. FM radio transmissions began in 1956 and cover most of Devon and eastern parts of Cornwall.
