Rugby VLF Building

The Pawsey family recently wrote to us:


My aunt is clearing her home. Her husband, David Pawsey, worked for STC in Sydney during WW2, and as an electrical engineer subsequently. Among his papers is a 1960s profile of the UK Rugby Radio Station (small document).

Here is a scanned verion of that document that they have kindly sent to us:

Some history of the Rugby Radio Station from Wikipedia:

Following the end of the First World War the British government set about implementing plans for an Imperial Wireless Chain to link the countries of the British Empire. It was decided that the new wireless service would be state-run by the Post Office. The site east of Hillmorton, was chosen in 1923. Part of the site had previously been occupied by RAF Lilbourne between 1915 and 1920.

Its large very low frequency (VLF) transmitter came into service on 1 January 1926 and was originally used to transmit telegraph messages to the Commonwealth as part of the Imperial Wireless Chain. After the 1950s this transmitter, active as callsign GBR on 16.0 kHz, using Morse code and later on 15.975 kHz with frequency-shift keying FSK and minimum-shift keying MSK, was used for transmitting messages to submerged submarines. Criggion radio station acted as a reserve. The GBR transmitter was shut down on 1 April 2003 and was replaced by a new one at the Skelton transmitting station.

In 1927, a second transmitter was installed to initiate the first transatlantic commercial telephone service; linking New York and London on 60 kHz using single-sideband modulation. This transmitter was decommissioned in 1956 and became the time signal transmitter MSF. This new function developed from the decision, in 1951, to use the station to transmit modulated standard frequencies for scientific reference purposes. In 1972 these transmissions were consolidated onto the present frequency of 60 kHz and a further reference, that of a time signal, was added. In 1977 this took the form of the rolling slow code in use until April 2007, when BT's contract to transmit the time signal also passed to VT Communications, using their Anthorn radio station in Cumbria.


The aerial system at the VLF transmitter existed between 1926 and 2004 and consisted of twelve 250 metre (820 ft) high, guyed steel-framework masts insulated against ground and carrying an aerial wire. This wire was mainly destroyed by heavy iceloads in the winter of 1940. After the shutdown of GBR, the facility was only used for transmitting the MSF time signal. Therefore, eight of the twelve masts were obsolete and demolished on the night of 19 June 2004 to 20 June 2004.

A trial transmission of the LORAN-C navigation system was run at the station from June 2005 until March 2007.The remaining four 'tall' masts were demolished on 2 August 2007. The site is now being developed into a large new housing estate named Houlton, the first homes of which were occupied in December 2017.


Radio Heritage Foundation projects and activities connect radio, popular culture, history and heritage.

The charitable trust has been giving a voice to those involved in radio via our website since 2004 and will continue to do so.

We are inclusive of all visitors, regardless of race, color, sex, age, national origin, religion, sexual orientation, gender identity and/or expression, or disability and aim to connect people of all ages and cultures who love radio

We welcome a sense of wonder from the joy of listening via radio, and from memories retold for the enjoyment of all generations.

We prefer to use environmentally sustainable goods and services where we can afford to, and we provide free community access worldwide to our collections, published research, preservation and promotion activities in a completely paper-free environment.
