Radio Broadcasting
Radio broadcasting is transmission 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 which 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 ( amplitude modulation), FM radio stations transmit in FM (frequency modulation), which are older analog audio standards, while newer digital radio stations transmit in several digital audio standards: DAB (digital audio broadcasting), HD radio, DRM ( Digital Radio Mondiale).

Longwave
In radio, longwave, long wave or long-wave, and commonly abbreviated LW, refers to parts of the radio spectrum with wavelengths longer than what was originally called the medium-wave broadcasting band. The term is historic, dating from the early 20th century, when the radio spectrum was considered to consist of longwave (LW), medium wave, medium-wave (MW), and short wave radio, short-wave (SW) radio bands. Most modern radio systems and devices use wavelengths which would then have been considered 'ultra-short'. In contemporary usage, the term ''longwave'' is not defined precisely, and its intended meaning varies. It may be used for radio wavelengths longer than 1,000 m i.e. frequencies up to 300 kilohertz (kHz), including the International Telecommunication Union, International Telecommunication Union's (ITU's) low frequency (LF, 30–300 kHz) and very low frequency (VLF, 3–30 kHz) bands. Sometimes the upper limit is taken to be higher than 300 kHz, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AM Broadcasting
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 (also known as "AM band") transmissions, but also on the longwave and shortwave radio bands. The earliest experimental AM transmissions began in the early 1900s. However, widespread AM broadcasting was not established until the 1920s, following the development of vacuum tube receivers and transmitters. AM radio remained the dominant method of broadcasting for the next 30 years, a period called the " Golden Age of Radio", until television broadcasting became widespread in the 1950s and received most of the programming previously carried by radio. Subsequently, AM radio's audiences have also greatly shrunk due to competition from FM (frequency modulation) radio, Digital Audio Broadcasting (DAB), satellite radio, HD (digital) radio, Internet radio, music streaming se ...

RTÉ Radio 1
RTÉ Radio 1 ( ga, RTÉ Raidió 1) is an Irish national radio station owned and operated by RTÉ and is the direct descendant of Dublin radio station 2RN, which began broadcasting on a regular basis on 1 January 1926. The total budget for the station in 2010 was €18.4 million. It is the most-listened-to radio station in Ireland. History The Department of Posts and Telegraphs opened 2RN, the first Irish radio station, on 1 January 1926. Station 6CK, a Cork relay of 2RN, joined the Dublin station in 1927, and a high-power transmitter at Athlone in County Westmeath opened in 1932. From the latter date the three stations became known as Radio Athlone, later being renamed Radio Éireann ("Irish Radio"/"Radio of Ireland") in 1937. Like most small European national stations at that time, Radio Éireann attempted to satisfy all tastes on a single channel. It broadcast a mixed schedule of light entertainment and serious drama, Irish language programming, and talks. Radio Éirean ...

Atlantic 252
Atlantic 252 was an Irish longwave radio station broadcasting across Ireland and Great Britain on 252 kHz (1190 metres) from its 1988 purpose-built transmission site at Clarkstown radio transmitter, County Meath, which provided service to Atlantic 252 from 1989 until 2002. The station's studios were located 12 km (7 mi) away in Mornington House, Summerhill Road, Trim, County Meath. Atlantic 252 also had sales offices and studios at 74, Newman Street in London. After its closure, the station's former frequency and transmitter were used for the failed TEAMtalk 252 project which lasted for just a few months in 2002. From 2004, the frequency was used by RTÉ to provide a version of RTÉ Radio 1 to the expatriate community in Britain from the Clarkstown radio transmitter. Since 2014 there have been several announcements of the impending closure of this transmitter but as of 2019 it remains on air albeit on significantly reduced power.

Digital Radio Mondiale
Digital Radio Mondiale (DRM; ''mondiale'' being Italian and French for "worldwide") is a set of digital audio broadcasting technologies designed to work over the bands currently used for analogue radio broadcasting including AM broadcasting—particularly shortwave—and FM broadcasting. DRM is more spectrally efficient than AM and FM, allowing more stations, at higher quality, into a given amount of bandwidth, using xHE-AAC audio coding format. Various other MPEG-4 and Opus codecs are also compatible, but the standard now specifies xHE-AAC. Digital Radio Mondiale is also the name of the international non-profit consortium that has designed the platform and is now promoting its introduction. Radio France Internationale, TéléDiffusion de France, BBC World Service, Deutsche Welle, Voice of America, Telefunken (now Transradio) and Thomcast (now Ampegon) took part at the formation of the DRM consortium. The principle of DRM is that bandwidth is the limiting factor, and com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lists Of Radio Stations By Frequency
A list is a set of discrete items of information collected and set forth in some format for utility, entertainment, or other purposes. A list may be memorialized in any number of ways, including existing only in the mind of the list-maker, but lists are frequently written down on paper, or maintained electronically. Lists are "most frequently a tool", and "one does not ''read'' but only ''uses'' a list: one looks up the relevant information in it, but usually does not need to deal with it as a whole".Lucie Doležalová,The Potential and Limitations of Studying Lists, in Lucie Doležalová, ed., ''The Charm of a List: From the Sumerians to Computerised Data Processing'' (2009). Purpose It has been observed that, with a few exceptions, "the scholarship on lists remains fragmented". David Wallechinsky, a co-author of ''The Book of Lists'', described the attraction of lists as being "because we live in an era of overstimulation, especially in terms of information, and lists help us ...
