Celebrating 90 years of British Broadcasting, 1920 - 2010

摘要

Geoff Watts GOEVW writes: January 15th, 1920 saw the first broadcasts from MZX in Chelmsford and June 15th will be the 90th anniversary of the recital by Dame Nellie Melba, the famous Australian Prima Donna. Dame Nellie Melba gave her historic 30 minute concert from the Marconi New Street works in Chelmsford. The experimental Station MZX transmitted on a wavelength of 2,750 metres using a 15kW transmitter and a T' antenna.rnAlthough the Dame Nellie concert, the first by a recognised professional artiste, is generally recognised to have been a turning point in British Broadcasting history, it was not the first broadcast. Two Marconi engineers, W. Ditcham and Captain H. Round started what was probably the first ever true telephony 'broadcasts' months earlier.
