2ZY
Résumé
2ZY was the name of a radio station established by the British Broadcasting Company in Manchester, England, in 1922. Part of the newly nationalised British Broadcasting Corporation from 1 January 1927, the station continued broadcasting under the 2ZY name until its transmissions came to be referred to, from 9 March 1930, as "the Manchester programme". Subsequently, on 17 May 1931, the Manchester station – broadcasting from a new high-powered station at Moorside Edge – became the main production centre of the newly launched BBC North Regional Programme, which was to remain on air until the outbreak of the Second World War in 1939.
2ZY aired its first test transmission on 450 metres on 17 May 1922 and regular broadcasting from the station started on 15 November 1922, just one day after sister station in London, 2LO, had begun transmitting daily programmes. On the same day, 5IT began in Birmingham and eight other stations opened in subsequent months across Britain. The frequency chosen for 2ZY was then 385 metres medium wave. The programmes were at first broadcast from the Metropolitan-Vickers electricity works in Old Trafford. The ornate iron water tower at the works was the site of the transmitter.
From 1922 to 1924 all the programmes broadcast by these early stations were made locally as networking was not technically possible, but when quality improved the majority of output was provided by London. The idea of re-transmitting a service in a neighbouring area was tried in May 1924 when the Glasgow service from station 5SC was picked up and rebroadcast from a transmitter in Edinburgh. 2ZY became the first English station to do this when its signal was "relayed" to a transmitter covering Liverpool from 11 June 1924 (the station was called 6LV) and the Leeds/Bradford area on 8 July 1924 (station 2LS). Hull was next (station 6KH, from 15 August 1924) and Nottingham followed (station 5NG opened on 16 September 1924). The last of that period was a relay to the Stoke-on-Trent area (from station 6ST) which began on 21 October 1924.
