Daventry transmitter
The Borough Hill is a former transmitter of the BBC for long , medium and short wave . The location was Borough Hill, east of the city of Daventry . Daventry in Northamptonshire was chosen because of its central location, some 50 km southeast of Birmingham . The last transmitter was switched off in 1992.
Long wave
The long wave transmitter went into operation on July 27, 1925, replacing a test transmitter north of London . It had an output of 25 kW and initially transmitted on frequencies between 187 and 193 kHz, from January 15, 1934, finally on 200 kHz. From March 9, 1930, the national program, taken over by the secondary transmitters at the most important medium-wave locations, was broadcast, while the medium-wave transmitters broadcast the regional program ("London Regional", "West Regional", etc.).
On October 7, 1934 Daventry was replaced by the stronger transmitter Droitwich . During the Second World War , the station was reactivated to broadcast programs of the European Service of the BBC in single-frequency operation with Droitwich and a new station set up on the medium-wave station Brookmans Park . This was necessary to German bombers, the aim for to complicate the transmitter.
Medium wave
The medium wave transmitter was put into operation on August 21, 1927 and replaced the Birmingham transmitter and its secondary transmitter. The program produced in the Birmingham studio was called "Daventry Experimental", from March 9, 1930 " Midlands Regional". The 25 kW transmitter worked on frequencies between 610 and 767 kHz. On February 17, 1935, he was also replaced by Droitwich.
The Copenhagen Wave Plan , which came into force on March 15, 1950 , assigned Great Britain the frequency of 647 kHz for the third program introduced after the war. A 60 kW transmitter at the Daventry site was initially used for this purpose, and the final Dodford transmitter (150 kW) was put into operation on April 8, 1951. This was also listed as "Daventry". This transmitter was in operation until 1978, when it was replaced by Droitwich.
Shortwave
Before World War II, Daventry was the only British shortwave transmitter. During the war, shortwave transmitters were built in Daventry and numerous other locations. Most of them stayed in operation later.
At the end of 1992, the shortwave location Daventry was closed, thus ending the history of the traditional station.
