Daventry transmitting station
The Daventry transmitting station was a major broadcasting facility located on Borough Hill on the outskirts of Daventry, Northamptonshire. It operated from 1925 until 1992, carrying long-wave, medium-wave and short-wave broadcasts at different times in its history. In its heyday the site had antennas supported by over 40 masts and towers on an antenna field extending to hundreds of acres. Since 1992, only DAB services have been broadcast from the site using a single mast.
==Long wave transmitter==
During 1923, the British Broadcasting Company's chief engineer, Peter Eckersley, deduced that it would be possible to provide a broadcast service to most of the United Kingdom using a single high-power long wave transmitter located in central England. A 50-acre site on Borough Hill was acquired by the BBC for this purpose. A T-aerial was suspended between two masts, each 500 ft high and spaced by 800 ft. The station's 25 kW transmitter used the same 5XX callsign as its experimental predecessor at Chelmsford.
The Daventry transmitter took over from Chelmsford on 27 July 1925. It opened on 187.5 kHz, but changed frequency to 187 kHz in 1927, 193 kHz in 1929 and finally 200 kHz in 1934. The transmitter was replaced by a higher-powered one at Droitwich transmitting station later the same year.
