Introduction
Radio Broadcasting in the UK began in 1920 with Marconi's experimental station 2MT located in
Writtle, Essex. Guglielmo Marconi brought together his own research together with the work of
scientists, being particularly inspired by the work of Heinrich Hertz, but bringing together the work of
others such as Augusto Righi, who was Marconi's tutor, Michael Faraday, James Clerk Maxwell, Nikola
Tesla, David Hughes, Sir Oliver Lodge and Alexanda Popov to produce commercially viable wireless
communication systems.

How it all began
Michael Faraday worked on many electromagnetic theories from around 1831 to 1857. James Clerk
Maxwell had mathematically predicted that radio waves existed in 1864 and it was Heinrich Hertz who
produced the first man-made radio waves using a 'Spark-Gap' transmitter between 1885 and 1889.
Nikola Tesla developed many complex electromagnetic principles while it was David Hughes who
invented the microphone in 1880. In 1894 Sir Oliver Lodge perfected a radio wave detector called a
Coherer, a predecessor of the electronic valve method of detection.
Marconi
Marconi was born on April 25th 1874 and was brought up in England
and Italy. He attended scientific lectures given by Augusto Righi and did
much work on the development of radio. By 1895 Marconi had made
experimental transmissions using 'Hertzian Waves' over several
kilometers in Italy. However insufficient interest was shown in his native
Italy so, in 1896, he moved to London where the benefits of the wireless
telegraphy system were demonstrated to General Post Office and Armed Forces. After much
development work Marconi made the first radio transmission across the Atlantic from Poldhu,
Cornwall to Signal Hill, St Johns, Newfoundland, Canada in December 1901.
Marconi is often credited with the invention of radio, but perhaps he should be credited with the
bringing together of many other scientists work to evolve a workable wireless communication system.
However even this statement can be challenged, since it is probable that the Russian scientist
Alexander Stepanovitch Popov actually stole the lead over Marconi's work.

First steps
Marconi set up an experimental transmitting station at Poldhu Point, not far from The Lizard and
Mullion in Cornwall. Here he built very large aerial systems that would be required to send his signal as
far as possible - the aim was to send his radio signals across the Atlantic - the great "Atlantic Leap".
One of the first aerial systems was circular in structure, but this was damaged by gales. Another type of
aerial system was fan shaped, shown on the right. The transmitter was a simple, but powerful, spark
gap type that essentially produced clicks that could convey the Morse Code.
At this time it was not possible to transmit actual sounds such as voice or music by radio waves.
The 12th December 1901 marked Marconi's very first trans-Atlantic transmission involved sending the
letter S in Morse Code from his station on the cliff at Poldhu. This radio signal was received by Marconi
at Signal Hill in Newfoundland, using a large antenna about 600 feet long suspended from a kite. The
signal heard was just the three faint clicks dot dot dot that denote the letter S in Morse Code. After
much more development work Marconi's radio system would provide the world with one of the most
important communication tools known to mankind.
Marconi's work was a tremendous achievement and over the next few years Marconi's wireless
telegraphy sets, which used Morse Code, were fitted to many to ocean going ships so that they could
communicate with wireless telegraphy stations on the mainland.
The Sinking Of The Titanic: Marconi's wireless telegraphy system saved the lives of over 700 passengers
aboard the Titanic which sank in April 1912. The distress calls were sent out to near-by shipping using
the Marconi apparatus and were received by the Carpathia which was to effect a rescue. Marconi's
work was widely credited for saving the lives of hundreds of people. The military also found a use for
the wireless equipment which was used during the First World War.

Radio stations
2MT Writtle (Near Chelmsford, Essex)
It was the invention of the Thermionic Valve, by Flemming and De
Forest, in 1906 that allowed Marconi to eventually produce a reliable
'Carrier Wave' that could be 'modulated' so that voice and music could
be transmitted, rather than the spark-gap transmitters that had been
used to produce the dots and dashes used by the Morse Code signals that had hitherto been
employed. Using this new method - the carrier wave - enabled Marconi to transmit speech and music
from his experimental station 2MT in 1920.
Marconi sited this experimental station, 2MT, in an ex army hut at Writtle, Essex . The station was
initially allowed to transmit its test transmissions for only half an hour a week.
Dame Nellie Melba made one of the first broadcasts from 2MT at 7.10 pm on 15th June 1920.
Consisting of a concert of opera music to entertain the listeners, the broadcast opened with a recital of
Home Sweet Home and finishing with the national anthem. Those early wireless listeners - the early
radio amateurs - heard the broadcasts from Chelmsford to Paris, Madrid and Berlin.
Two years later, on 14th February 1922, 2MT in Writtle would commence broadcast daily half hour
programmes of news and entertainment which lasted for a period of nearly three years. Listeners
could tune in using crystal sets, the simplest form of radio receiver that required no external power or
batteries. All that powers the headphones of a crystal set is the energy collected from its aerial which
is derived from the radio waves sent by the transmitter of the radio station to which the set is tuned.
Captain Peter Eckersley was the first engineer at 2MT in Essex. and also became an on-air announcer.
Eckersley found that he had a flair for radio broadcast entertianment and put on many performances,
along with his small team of colleagues, from the studio in the old army hut. The programmes would
consist of records, spoofs, plays and other music.
Page 6
By May 1922, seeing the commercial potential of radio broadcasting, Marconi's company was in talks
with wireless set manufactures and other interested organisations to set up more broadcasting
stations around the country under an umbrella organisation called the British
Broadcasting Company (BBC).
The main companies involved in the creation of the British Broadcasting Company and guaranteeing its
finances for an initial period of two years were The Marconi Co; The General Electric Co; The Radio
Communications Co; Metropolitan Vickers Co; Western Electric Co and The British Thompson-Houston
Company. Their joint mission was, of course, to make money from the sale of radio sets - and people
would only want to buy into this exciting new technology if there were wireless programmes to listen
to.
2LO London
Until now the government had done its best to thwart Marconi's efforts to establish public radio
broadcasting for the masses, but would eventually capitulate and grant the BBC a licence to operate a
public radio service.
Marconi's company would aim to provide quality programmes consisting of variety entertainment,
concerts and plays and fund the transmission of these wireless programmes by a tax collected from the
sale of wireless sets and from a licence fee administered by the Post Office. Along with 2MT in
Essex, two further experimental stations, 2LO in London and 2ZY in Manchester had been established
on May 11th and 16th respectively.

The Company era
On October 18th 1922 the British Broadcasting Company was
formed - with the government indeed granting the BBC a
licence to operate - and November 14th 1922 saw the official
opening of the BBC London station 2LO, managed by Arthur Burrows, on a wavelength of 369 meters
from Marconi House on The Strand. John Reith was appointed General Manager of the BBC on 14th
December 1922, with Captain Peter Eckersley, the first engineer at 2MT, appointed as the BBC's first
Chief Engineer. The BBC was formally registered as a limited company on 15th December 1922.
On 15th November 1922 the BBC was registered and the BBC's Manchester station, 2ZY, was officially
opened on 375 meters transmitting from the Metropolitan Vickers Electricity works in Old Trafford. On
November 16th BBC Birmingham opened with 5IT transmitting from the General Electric Company
works at Witton using 420 meters. BBC Newcastle, 5NO, was the last station to open in 1922 from a
transmitter at Eldon Square using 400 meters. These 'main' stations broadcast with a power of 1.5
kilowatts.
On December 23rd 1922 the BBC broadcast the first orchestral concert, the first programme of dance
music, the first radio talks programme and commenced the first regular bulletin of general news from
London, provided from the Reuters news source. On Christmas Day 1922 the BBC broadcast "The Truth
About Father Christmas" - the first play for radio - and transmitted the first religious programme.
On January 17th 1923 the original station 2MT in Essex was closed, but more BBC stations were to be
established around the country: BBC Cardiff, 5WA, opened on February 13th on 353m from a
transmitter at the Castle Avenue electric works; BBC Glasgow, 5SC, opened using a transmitter at Port
Dundas on 420m, while BBC Aberdeen, 2BD, started on October 10th using 459m from a transmitter at
the Aberdeen Steam Laundry. BBC Bournemouth, 2BD, opened on October 17th on 385m from a
transmitter at North Cemetery, and on the 16th November 2FL Sheffield opened. The first Gaelic
broadcast from BBC Aberdeen was made on 2nd December 1923.
Page 8
1924 saw more expansion with the opening of 5PY Plymouth on 28th March, the 2EH Edinburgh relay
of 5SC on May 1st and in June stations 6LV and 2LS were opened to bring a relay of 2ZY to Liverpool
and Leeds/Bradford. On September 15th 1924 BBC Belfast, 2BE, was opened. Other relay stations
were also opened; 6KH in Hull; 5NG in Nottingham; 2DE in Dundee on 12th November 1924; 6ST in
Stoke on Trent and 5SX in Swansea, which opened on the 12th December 1924. The relay stations in
the system broadcast with a power of 100 watts. On December 28th the BBC's Chelmsford transmitting
station began to transmit an alternative programme.
During 1923 the number of radio receiving licences, which cost 10 shillings, grew to 500,000 driven by
the high quality programmes transmitted. BBC London, 2LO, moved from Marconi House to new
studios at Savoy Hill, while BBC Birmingham, 5IT, moved to new studios at The Picture House on New
Street.
On November 14th 1923 John Reith became Managing Director of the BBC and declared that the BBC
must bring the best broadcasting to the widest possible number of homes. John Reith was a Scottish
engineer who envisaged that the BBC's mission must be to "inform, educate and entertain".
On 31st December 1923 Big Ben chimed in the new year for the first time by radio, while just a matter
of weeks later, in February 1924, the Greenwich Time signal ("The Pips") was broadcast for the first
time on BBC radio. By the mid 1920's programmes from the BBC could be received my most of the
population.
Company becomes Corporation
The BBC's licence expired 31st December 1926 and a government committee recommended that the
Britich Broadcasting Company should be replaced with a public authority. The first Royal Charter was
agreed upon and published on 20th December 1926 enabling the British Broadcasting Company to be
nationalised and therefore to become the British Broadcasting Corporation with the granting of the
first 10 year Royal Charter.
Page 9
While the BBC was no longer an independent commercial company, the aim of the charter was that it
would remain independent of central government interference as the corporation would, from there
on, be overseen by an appointed Board of Governors, John Reith being the first Director General (DG)
who was also knighted in 1927.
In 1929, the rather puritanical, John Reith felt that he had to sack Peter Eckersley, the original engineer
at 2MT, for having an extra-marital affair and for subsequently getting divorced.
Under Reith's leadership the BBC continued its mission to "inform, educate and entertain" and
contined broadcasts of talks, variety and concerts. However, due to pressure from the newspaper
industry the BBC was not allowed to transmit its news bulletins, assembled by the news agencies, until
after 7pm - after the newspapers had been printed, distributed and sold! This was a measure taken so
that newspaper sales would not be lost to a BBC radio news service.
By the early 1930's the premises at Marconi House at Savoy Hill were becoming inadequte for the
BBC's needs therefore the corporation had to find and establish a new operating centre. In 1932 the
BBC moved into purpose built studios at Portland Place in London - the famous and now iconic
Broadcasting House.
Popular entertainment prorammes broadcast by the BBC in the 1930's included "ITMA" - It's That Man
Again and "Band Wagon".
The regional scheme
On 21st August 1927 the BBC opened the new 5GB station at the Daventry transmitting site using
medium waves, this brought a new Regional Programme as an alternative to the longwave National
Programme to the Midland Region. 5GB was a new departure for the BBC, not only did it mark the
start of a new policy 'The Regional Scheme', but it also required a high power transmitter of between
30 - 50 kilowatts, bigger than any transmitter previously built.
Page 10
The Geneva Plan of 14th November 1926 had reduced the number of medium wave frequencies
available to the BBC so from now on the BBC would develop this pattern of services under The Regional
Scheme. It was this development that led to the eventual demise of the original pioneering low power
local stations such as 2LO, 2ZY and 5IT by 1931. These original low power local stations closed and
were replaced by the two BBC radio services; National and Regional.
With the successful establishment of 5GB at Daventry the Regional Programme was provided on
Medium Wave for the Midlands area. 5GB was deemed to be a great success and there followed the
establishment of seven regional services across the UK, each broadcasting programmes from its own
local studio - The regions covered were Midlands, West, North, South East, Scottish, Welsh and N
Ireland. The National Programme was broadcast from the centrally located transmitting station 5XX
on longwave from Daventry, backed up by medium wave fillers in areas where the long wave signal
was weak.
This new Regional Scheme required the BBC to build new, more powerful, transmitting stations that
could carry both the National Programme and the Regional Programme services to the whole country.
The first of these "Twin Wave" stations to be purpose built specifically for the Regional Scheme was
Brookmans Park in Hertfordshire - a meticulously chosen site capable of providing signals to London
and the South East. The station was a huge undertaking, using four large lattice towers, two towers
used to support the aerial system for each service.
The Brookmans Park station opened in 1929 using wavelengths of 261 meters* for the National
Programme at 70 kilowatts and 356 meters for the Regional Programme at 40 kilowatts. Because the
National Programme used shorter wavelengths (higher frequencies) the range was somewhat less than
that of the Regional Programme on 356 meters, however the longwave transmitter 5XX at Daventry
also transmitted the National Programme and would fill in any areas of poorer reception. The BBC
ensured that the new transmission arrangements would provide robust reception for listeners with
both valved radios and humble crystal sets which were still being used.
Page 11
On September 6th 1934 the BBC opened a new Twin Wave station located near the town of Droitwich
to serve the Midlands region. Droitwich was to replace the existing transmitting site at Daventry.
Initially the 5XX service was moved from Daventry to Droitwich using powerful new transmitters that
produced 150 kilowatts. Five months later, on February 17th 1935, 5GB opened from Droitwich
radiating the Regional Programme on medium wave with a power of 50 kilowatts; this replaced the
original 5GB 25 kilowatt transmitter at Daventry.
Eventually further high power "Twin Wave" stations would be built at Moorside Edge (North),
Washford Cross (West) and Westerglen (Scottish). Additional high power transmitting stations were
also established at Lisnagarvey ('N.Ireland' on 977 kHz at 100 kW), Burghead ('Scottish' on 767 kHz at
60 kW), Stagshaw ('North' on 1122 kHz at 60 kW), Clevedon ('West' on 1475 kHz at 20 kW) and Start
Point ('West' on 1050 kHz at 100 kW) to bring a Regional Programme to most areas of the UK.
Additionally Penmon (Welsh) and Redmoss (Scottish) carried lower powered (5kW) transmissions of
the Welsh and Scottish regional programme.
Long wave
Until 1924 the BBC had been providing local programmes on the medium waves from the chain of
relatively low power transmitters established around the country. In June of that year 5XX, a new
experimental transmitting station at Marconi's Chelmsford site, was opened using the long
waves enabling the BBC to be heard over most of the country and also overseas with the alternative
National Programme enabling people in Britain, who were beyond reach of a local medium wave
transmitter, to hear the BBC.
The experimental long wave station at Chelmsford was deemed a great success and to a permanent
site was sought out and on July 25th 1925 the 5XX transmitter was moved to Daventry in
Northamptonshire. Daventry was a more centralised location and with a new more powerful 25kW
transmitter on 1562 meters (187.5 kHz) enabled improved coverage across a greater area of the UK.
By this time there were over 1½ million radio receivers in use, many were still crystal sets, but valved
Page 12
radios which could amplify the signals enough to enable loudspeaker operation, though more
expensive, gradually gained popularity.
With the new 5XX Daventry station in operation the BBC experimented with stereophonic broadcasts
for the first time with a concert from Manchester being broadcast from all transmitters, 5XX longwave
transmitting the right hand channel, while the local mediumwave stations broadcast the left hand
channel.
Short wave
John Reith had been keen to provide an overseas radio service since 1924 and eventually after
technical and financial delays, a licence to broadcast on short wave was obtained from the Post Office
in 1926, and the experimental station G5SW, using the short waves, opened at the Chelmsford site on
11th November 1927. It was intended that G5SW would transmit programmes from Britain to the
Empire from a 10 kW transmitter.
The G5SW short wave transmissions were also a success for the BBC and this led to the establishment
of a permanent Empire Station at Daventry in December 1932 using two 15 kW transmitters and a
number of directional aerial arrays to beam the signals to various parts of the globe - the first
programmes from the BBC Empire Service being broadcast on 19th December 1932. King George V
made the first Round-the-Empire broadcast and the Christmas Day broadcast on December 25th 1932.

Normandie calling
While the BBC was expanding its transmission facilities it continued providing quality programming of
great broadcasting worth. However some listeners began to find this type of programming a little dull
and when Radio Normandie commenced programmes in English from France in 1931 many British
listeners tuned in to 269meters (1113 kc/s), later changed to 274 metres. Radio Normandie was a
commercial station established in 1929 and based at Villa Vincelli la Grandier in Fécamp.
The English programmes were broadcast after the French programmes had gone off the air and were
supplied to the station by the International Broadcasting Company (IBC), an organisation that had been
setup by Philco radio salesman Captain Leonard F Plugge in 1930. On Sundays, when the BBC was
concentrating on religious output, Radio Normandie was said to command 80% of the British radio
audience.
The programmes were comparatively lively and fun, and financed by advertising, Philco being an early
sponsor. Henleys, a car sales company, successfully launched the SS1 motor car on the station. This
proved to sceptics that radio advertising really worked. Henley's went on to become a chain of car
showrooms and repair garages from which later Jaguars, Rovers, Land-Rovers, etc, were sold, while SS
Cars (aka Swallow Sidecars) went on to become Jaguar Cars!
Radio Normandie could be heard across Southern England and beyond and proved to be such a success
with the audience that programmes were expanded in 1932 and ran from 6pm to 3am. Roy Plomley
and Bob Danvers-Walker were voices that could be heard on Radio Normandie in the late 1930's, along
with commercials voiced by Gracie Fields.
Meanwhile the BBC Chamber Orchestra was broadcast for the first time on 18th December 1931 and
later, having moved to moved to new headquarters at Broadcasting House in Portland Place in May
1932, the BBC commenced experiments with the Baird 30 line mechanical television system, while on
December 19th The Empire Service was inaugurated.
Page 14
As 1933 arrived so did Radio Luxembourg, using a large 200kW transmitter on 1190 meters longwave,
English programmes started in June running from 5pm to midnight. Like Radio Normandie the
programmes were of a less formal nature than those provided by the BBC and also funded by
advertising and sponsorship. Again the programmes proved to be a hit with the British listening public
and by December 3rd 1933 Radio Luxembourg had expanded English programmes to run from 3.30 pm
to midnight.
Pirate radio
UK pirate radio (unlicensed illegal broadcasting) was popular in the 1960s
and experienced another surge of interest in the 1980s.[1] There are currently
an estimated 150 pirate radio stations in the UK. A large proportion of these
pirate radio stations operate in London, with significant clusters
in Harlesden, Stoke Newington, Southwark and Lambeth.
1960s"Pirate radio" in the UK first became widespread in the early 1960s when pop music stations such
as Radio Caroline and Radio London started to broadcast on medium wave to the UK from offshore
ships or disused sea forts. At the time these stations were not illegal because they were broadcasting
from international waters. The stations were set up by entrepreneurs and music enthusiasts to meet
the growing demand for pop and rock music, which was not catered for by the legal BBC
Radio services.
The first British pirate radio station was Radio Caroline, which
started broadcasting from a ship off the Essex coast in 1964. By
1967 twenty-one pirate radio stations were broadcasting to an
estimated daily audience of 10 to 15 million. The format of this
wave of pirate radio was influenced by Radio Luxembourg and
