History

Initially the power was 100 watts on 360 metres (832 kHz). 2LO was allowed to transmit for seven minutes, after which the "operator" had to listen on the wavelength for three minutes for possible instructions to close down. On 14 November 1922 the station was transferred to the new British Broadcasting Company which in 1923 took up the nearby Savoy Hill for its broadcasting studios. At midnight on New Year's Eve 1923, the twelve chimes of Big Ben were broadcast for the first time to mark the new year.^[1]

In 1927 the company became the British Broadcasting Corporation. On 9 March 1930 2LO was replaced by the BBC Regional Programme and the BBC National Programme.

Preservation and legacy

Parts of the 2LO transmitter in the Science Museum, London (2013)

The 2LO transmitter now belongs to the Science Museum, having been donated by Crown Castle International on 7 November 2002.^[2][3] It is displayed in the Information Age gallery on the second floor of the museum.

Marconi House was demolished in 2006, apart from the listed façade, which was incorporated into a new hotel complex.^[4] A first-hand account of a broadcast from 2LO is given in The Spell of London by H. V. Morton.

The 'LO' part of 2LO's callsign was adopted in 1924 by the metropolitan radio station in Melbourne which, since 1932, has been a part of the Australian Broadcasting Corporation. The station, 3LO, still has this callsign allocated to it, but since 2000 it has used different on-air names: as from 2017, it was 774 ABC Melbourne; and it is now ABC Radio Melbourne.^[5]

The amateur radio callsign G2LO is currently held by the staff association at Arqiva, formerly Crown Castle International, formerly the domestic part of BBC Transmitter Department.^[6]

In fiction

2LO is briefly mentioned in the 1928, Lord Peter Wimsey, detective short-story The Entertaining Episode of the Article in Question by Dorothy L. Sayers.^[7]

2LO is mentioned in Chapter 32 of Anthony Burgess’s 1980 novel Earthly Powers, as part of a fictional episode involving the narrator’s brother.

A 2LO broadcast with a weather forecast and news bulletin is mentioned in Chapter V of Sir Arthur Conan Doyle's The Maracot Deep, first published as a serial in 1927.^[8]
