In 1929, Baldock Radio Station opened its doors for the first time.

That was the start of a nine-decade journey (and counting) that would see it evolve from a radio receiving station to the home of Ofcom’s work on managing the airwaves Baldock Radio Station began operating in 1929.

It was created as a part of the Imperial Wireless Chain, an international communications network to link the countries of the British Empire. In that same year, it helped to complete the first transatlantic radiotelephone call, made to the UK from Rocky Point, New Jersey, USA.
