FM Broadcasting In The UK
FM sound broadcasting began in the United Kingdom on 2 May 1955 when the BBC started an FM broadcasting service the Light Programme, the Third Programme and the Home Service to the south east of England. There are now over 40 BBC and over 250 commercial FM sound broadcasting stations in the United Kingdom. BBC The BBC began using ''FM sound broadcasting'' in 1955, but at that time AM sound broadcasting predominated. The BBC's 'popular music' station, BBC Radio 1, opened in 1967 but only broadcast on MW until the end of the 1980s, and had 'borrowed' BBC Radio 2's FM frequencies for approximately 24 hours each week. 1987 saw the switch on of Radio 1's first full time FM frequency, and in 1995, FM coverage of Radio 1 matched that of the other BBC national stations that also aired on FM. During the start of this period, Radio 1 had gradually reducing at the end of the 1980s until the final 'borrow' took place in March 1990, five months before Radio 2 became the BBC's first FM- ...

FM Broadcasting
FM broadcasting is a method of radio broadcasting that uses frequency modulation (FM) of the radio broadcast carrier wave. Invented in 1933 by American engineer Edwin Armstrong, wide-band FM is used worldwide to transmit high fidelity, high-fidelity sound over broadcast radio. FM broadcasting offers higher fidelity—more accurate reproduction of the original program sound—than other broadcasting techniques, such as AM broadcasting. It is also less susceptible to Electromagnetic interference, common forms of interference, having less static and popping sounds than are often heard on AM. Therefore, FM is used for most broadcasts of music and general audio (in the audio spectrum). FM radio stations use the very high frequency range of radio frequency, radio frequencies. Broadcast bands Throughout the world, the FM broadcast band falls within the VHF part of the radio spectrum. Usually 87.5 to 108.0 MHz is used, or some portion of it, with few exceptions: * In the Commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Simulcast
Simulcast (a portmanteau of "simultaneous broadcast") is the broadcasting of programs or events across more than one resolution, bitrate or medium, or more than one service on the same medium, at exactly the same time (that is, simultaneously). For example, Absolute Radio is simulcast on both AM and on satellite radio. Likewise, the BBC's Prom concerts were formerly simulcast on both BBC Radio 3 and BBC Television. Another application is the transmission of the original-language soundtrack of movies or TV series over local or Internet radio, with the television broadcast having been dubbed into a local language. Yet another is when a sports game, such as Super Bowl LVIII, is simulcast on multiple television networks at the same time. In the case of Super Bowl LVIII, the game's main broadcast channel was CBS, but viewers could watch it on other CBS-owned television channels or streaming services as well; Nickelodeon and Paramount+ showed the English-language broadcast, ...

Radio Data System
Radio Data System (RDS) is a communications protocol standard for embedding small amounts of digital information in conventional FM broadcasting, FM radio broadcasts. RDS standardizes several types of information transmitted, including time, station identification and program information. The standard began as a project of the European Broadcasting Union (EBU), but has since become an international standard of the International Electrotechnical Commission (IEC). Radio Broadcast Data System (RBDS) is the official name used for the U.S. version of RDS. The two standards are only slightly different, with receivers able to work with either system with only minor inconsistencies in the displayed data. Both versions carry data at 1,187.5 bits per second (about 1.2kbit/s) on a 57 kHz subcarrier, so there are exactly 48 cycles of subcarrier during every data bit. The RBDS/RDS subcarrier was set to the third harmonic of the 19 kHz FM stereo#Stereo FM, FM stereo pilot tone to mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Independent National Radio
Independent National Radio (INR) is the official term for the three national commercial radio stations currently or previously broadcasting on analogue radio in the United Kingdom, beginning in 1992. One station was allocated an FM licence, and the other two were allocated AM medium wave frequencies previously used by BBC Radio 3 and BBC Radio 1. Background The stations came about following the Broadcasting Act 1990 which allowed for the launch of independent national radio (INR) stations in the United Kingdom. The Radio Authority was mandated to award three INR licences. The FM licence (INR1) had to be for a 'non-pop' station, and one (INR3) had to be for a predominantly speech-based service. The remaining licence (INR2) was to be open to 'all-comers'. The licences were to be awarded to the highest cash bidder, providing that the applicant met criteria set down in the Broadcasting Act. Plans for a fourth station, using 225 kHz long wave, were mooted in 1996 but were aband ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Independent Local Radio
Independent Local Radio is the collective name given to commercial radio stations in the United Kingdom. As a result of the buyouts and mergers permitted by the Broadcasting Act 1990, and deregulation resulting from the Communications Act 2003, most commercial stations are now neither independent (although they remain independent from the BBC) nor local, as almost all of them are now relays of a national brand, with all remaining locality reduced to nothing more than a weekday regional programme and localised commercials, news, weather and peak-time travel information. The same name is used for Independent Local Radio in Ireland. History Development of ILR Until the early 1970s, the BBC had a legal monopoly on radio broadcasting in the UK. Despite competition from the commercial Radio Luxembourg and, for a period in the mid-1960s, the off-shore " pirate" broadcasters, it had remained the policy of both major political parties that radio was to remain under the BBC.

BBC Local Radio
BBC Local Radio (also referred to as Local BBC Radio) is the BBC's local and regional radio division for England and the Channel Islands, consisting of 39 stations. As of December 2024, the network broadcasts to a combined audience of 7.1 million, with a listening share of 4.6%, according to RAJAR. History The popularity of pirate radio was to challenge a then very "stiff" and blinkered management at the BBC. The most prominent concession by the BBC was the creation of BBC Radio 1 to satisfy the ever-demanding new youth culture with their thirst for new, popular music. The other, however, was that these pirate radio stations were, in some cases, local. As a result, BBC Local Radio began as an experiment. Initially, stations had to be co-funded by the BBC and local authorities, which only some Labour-controlled areas proved willing to do. Radio Leicester was the first to launch on 8 November 1967, followed by Leeds, Stoke, Durham, Sheffield, Merseyside, Brighton, and Not ...

Restricted Service Licence
A UK Restricted Service Licence (often called an RSL) is typically granted to radio stations and television stations broadcasting within the UK to serve a local community or a special event. Licences are granted by the broadcasting authority Ofcom (formerly the Radio Authority and the Independent Television Commission, respectively). History In 1972, the Independent Broadcasting Authority was created and given responsibility for regulating independent television and radio services in the UK. Over time, the demand for local services increased, and finally prompted an Act of Parliament to deregulate the respective industries and facilitate new long-term and short-term broadcast licences. In 1990, the Broadcasting Act 1990 became law, and led to the establishment of two licensing authorities: the Radio Authority to license new radio services and monitor existing licences, and the Independent Television Commission, to license new short-term television services.

Broadcasting Service
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. The encoding of a radio broadcast depends on whether it uses an analog or digital signal. Analog radio broadcasts use one of two types of radio wave modulation: amplitude modulation for AM radio, or frequency modulation for FM radio. Newer, digital radio stations transmit in several different digital audio standards, such as DAB (Digital Audio Broadcasting), HD radio, or DRM (Digital Radio Mondiale). ...
