2MT was the first British radio station to make regular entertainment broadcasts, [1] and the "world's first regular wireless broadcast" for entertainment. Transmissions began on 14 February 1922 from an ex-Army hut next to the Marconi laboratories at Writtle, near Chelmsford in Essex. Initially the station only had 200 watts and transmitted on 700m (428 kHz) on Tuesdays from 20:00 to 20:30.
Two Emma Toc (as it was called in the British Army Signalling Corps spelling alphabet of the day) was a surprising success. The presenter, producer, actor-manager and writer was Captain P. P. Eckersley, a Marconi engineer. His regular announcement; "This is Two Emma Toc, Writtle testing, Writtle testing", became in a short time quite well known. [2]
2MT led to the creation of its sister station 2LO, and subsequently the BBC. 2MT did not itself become part of the BBC and closed down on 17 January 1923.
Peter Eckersley went on to become the founding Chief Engineer at the British Broadcasting Company.
The Marconi Hut site at Writtle is commemorated by a nearby information board at Melba Court – named after Dame Nellie Melba who made Britain's first publicised entertainment broadcast from Marconi's New Street factory – unveiled in 1997 by Marconi's daughter Princess Elettra Marconi. The site was sold off and the land used for housing development in the 1990s.
A significant part of the original Writtle hut is now preserved at the Sandford Mill Museum of Science and Industry in North Chelmsford, where it forms part of a wireless and broadcasting historic exhibit.
In 1983, the Marconi Company main site in Stanmore, London, [3] found itself with an amateur radio club which applied for the call "2MT" to be issued. The UK authorities decided that they could not issue the call without the prefix "G" and so the Marconi Radio Society re-launched (G)2MT on the airwaves with many dignitaries present for the event.
The call has been used from then until 2004 when the Stanmore site was closed and moved to Capability Green, Luton, Bedfordshire, under the BAE Systems banner and which is now Selex Galileo. The call "G2MT" is not as well used, as the modern building construction has severely limited the possibilities of having a permanent transmitting station.[ clarification needed ] However, occasionally, one of the Marconi Radio Society members will bring along mobile transmitting equipment and give people the chance to hear (G)2MT over the air once again.
The 2MT call-sign has not been re-issued for regular use since 1922. However, in 2001, a special permit was given for it to be used to commemorate the 100th anniversary of the first wireless transmission across the Atlantic by Marconi in 1901. Details of this event can be found on the Chelmsford Amateur Radio Society (CARS) website. [4]
The 95th anniversary of 2MT was marked in February by amateur radio from the original hut and internet special events by a team effort of CARS with GB95-2MT, [5] EmmaToc [6] and Chelmsford Museum
The centenary of 2MT is being marked on 14th February 2022 by the village of Writtle and by amateur radio and internet special events, including by CARS with GB100-2MT [7] and EmmaToc.
Mainstream media also marked the anniversary including articles in the Daily Express [8] and iNews. [9]
Guglielmo Giovanni Maria Marconi, 1st Marquis of Marconi was an Italian inventor and electrical engineer, known for his creation of a practical radio wave–based wireless telegraph system. This led to Marconi being credited as the inventor of radio, and he shared the 1909 Nobel Prize in Physics with Karl Ferdinand Braun "in recognition of their contributions to the development of wireless telegraphy".
The early history of radio is the history of technology that produces and uses radio instruments that use radio waves. Within the timeline of radio, many people contributed theory and inventions in what became radio. Radio development began as "wireless telegraphy". Later radio history increasingly involves matters of broadcasting.
Shortwave radio is radio transmission using radio frequencies in the shortwave bands (SW). There is no official definition of the band range, but it always includes all of the high frequency band (HF), which extends from 3 to 30 MHz ; above the medium frequency band (MF), to the bottom of the VHF band.
AM broadcasting is radio broadcasting using amplitude modulation (AM) transmissions. It was the first method developed for making audio radio transmissions, and is still used worldwide, primarily for medium wave transmissions, but also on the longwave and shortwave radio bands.
Radio broadcasting is the broadcasting of audio (sound), sometimes with related metadata, by radio waves to radio receivers belonging to a public audience. In terrestrial radio broadcasting the radio waves are broadcast by a land-based radio station, while in satellite radio the radio waves are broadcast by a satellite in Earth orbit. To receive the content the listener must have a broadcast radio receiver (radio). Stations are often affiliated with a radio network that provides content in a common radio format, either in broadcast syndication or simulcast, or both. Radio stations broadcast with several different types of modulation: AM radio stations transmit in AM, FM radio stations transmit in FM, which are older analog audio standards, while newer digital radio stations transmit in several digital audio standards: DAB, HD radio, DRM. Television broadcasting is a separate service that also uses radio frequencies to broadcast television (video) signals.
Chelmsford is a city in the City of Chelmsford district in the county of Essex, England. It is the county town of Essex and one of three cities in the county, along with Colchester and Southend-on-Sea. It is located 30 miles north-east of London at Charing Cross and 22 miles south-west of Colchester. The population of the urban area was 110,625 in the 2021 Census, while the wider district has 181,763.
The British Broadcasting Company Limited (BBC) was a short-lived British commercial broadcasting company formed on 18 October 1922 by British and American electrical companies doing business in the United Kingdom. Licensed by the British General Post Office, its original office was located on the second floor of Magnet House, the GEC buildings in London and consisted of a room and a small antechamber.
The year 1922 in science and technology involved some significant events, listed below.
The village and civil parish of Writtle lies 1 mile (1.6 km) west of Chelmsford, Essex, England. It has a traditional village green complete with duck pond and a Norman church, and was once described as "one of the loveliest villages in England, with a ravishing variety of ancient cottages". The village is now home to Writtle University College, one of the UK's oldest and largest land-based colleges and a partner institution of the University of Essex, the grounds of which once housed a Royal hunting lodge, later the possession of the De Brus and De Bohun families.
The Marconi Company was a British telecommunications and engineering company that did business under that name from 1963 to 1987. Its roots were in the Wireless Telegraph & Signal Company founded by Italian inventor Guglielmo Marconi in 1897, which underwent several changes in name after mergers and acquisitions. The company was a pioneer of wireless long distance communication and mass media broadcasting, eventually becoming one of the UK's most successful manufacturing companies. In 1999, its defence equipment manufacturing division, Marconi Electronic Systems, merged with British Aerospace (BAe) to form BAE Systems. In 2006, financial difficulties led to the collapse of the remaining company, with the bulk of the business acquired by the Swedish telecommunications company, Ericsson.
2LO was the second radio station to regularly broadcast in the United Kingdom. It began broadcasting on 11 May 1922, for one hour a day from the seventh floor of Marconi House in London's Strand, opposite Somerset House.
Peter Pendleton Eckersley was a pioneer of British broadcasting, the first Chief Engineer of the British Broadcasting Company Limited from 1922 to 1927 and Chief Engineer of the British Broadcasting Corporation until 1929.
CINW was the final call sign used by an English language AM radio station in Montreal, Quebec, which, along with French-language sister station CINF, ceased operations at 7:00 p.m. ET on January 29, 2010. Owned and operated by Corus Quebec, it broadcast on 940 kHz with a full-time power of 50,000 watts as a clear channel, Class A station, using a slightly directional antenna designed to improve reception in downtown Montreal.
Marconi Research Centre is the former name of the current BAE Systems Applied Intelligence Laboratories facility at Great Baddow in Essex, United Kingdom. Under its earlier name, research at this site spanned military and civilian technology covering the full range of products offered by GEC-Marconi, including radio, radar, telecommunications, mechatronics and microelectronics.
The timeline of radio lists within the history of radio, the technology and events that produced instruments that use radio waves and activities that people undertook. Later, the history is dominated by programming and contents, which is closer to general history.
1920 in radio details the internationally significant events in radio broadcasting for the year 1920.
PCGG was a radio station located at The Hague in the Netherlands, which began broadcasting a regular schedule of entertainment programmes on 6 November 1919. The station was established by engineer Hanso Idzerda, and is believed to have been Europe's first sustained broadcasting station, as well as one of the first stations in the world to transmit entertainment intended for a general audience.
The New Street Works was a manufacturing plant built for the Marconi Company in Chelmsford, England in 1912. It is credited as being the first purpose-built radio factory in the world.
