2MT

2MT was the first British radio station to make regular broadcasts, and the third such radio station in the world (after PCGG in The Hague and KDKA in Pittsburgh, Pennsylvania)

Transmissions began on February 14, 1922 from an ex-Army hut next to the Marconi laboratories at Writtle, near Chelmsford in Essex. Initially the station only had 200 watts of power, and transmitted on 700m on Tuesdays from 2000 to 2030.

Two Emma Toc, in the phonetic alphabet of the day, was a surprising success, and led to the creation of its sister station 2LO, and subsequently the BBC. 2MT did not itself become part of the BBC and finally closed down on January 17, 1923.

The Marconi Hut site at Writtle is commemorated by a nearby information board at Melba Court, unveiled in 1997 by Marconi's daughter Princess Elettra Marconi. The site was sold off and the land used for housing development in the 1990s. Christened Melba Court it was named after Dame Nellie Melba who made Britain's first publicised entertainment broadcast from Marconi's New Street factory.

The site grid reference is TL681063.
