Music Radio
Music radio is a radio format in which music is the main broadcast content. After television replaced old time radio's dramatic content, music formats became dominant in many countries. Radio drama and comedy continue, often on public radio. Music drives radio technology, including wide-band FM, modern digital radio systems such as Digital Radio Mondiale, and even the rise of internet radio and music streaming services (such as Pandora and Spotify). When radio was the main form of entertainment, regular programming, mostly stories and variety shows, was the norm. If there was music, it was normally a live concert or part of a variety show. Backstage sound engineers who jockeyed discs (records) from one turntable to another to keep up with the live programming were often called disc jockeys. With the mass production and popularity of records in the mid 1940s, as well as the birth of TV, it was discovered that a show was needed to simply play records and hire a disc jockey to ...

Low-power Broadcasting
Low-power broadcasting is broadcasting by a broadcast station at a low transmitter power output to a smaller service area than "full power" stations within the same region. It is often distinguished from "micropower broadcasting" (more commonly "microbroadcasting") and broadcast translators. LPAM, LPFM and LPTV are in various levels of use across the world, varying widely based on the laws and their enforcement. Canada Radio communications in Canada are regulated by the Radio Communications and Broadcasting Regulatory Branch, a branch of Industry Canada, in conjunction with the Canadian Radio-television and Telecommunications Commission (CRTC). Interested parties must apply for both a certificate from Industry Canada and a license from CRTC in order to operate a radio station. Industry Canada manages the technicalities of spectrum space and technological requirements whereas content regulation is conducted more so by CRTC. LPFM is broken up into two classes in Canada, Low (5 ...

ICASA
The Independent Communications Authority of South Africa (ICASA) is an independent regulatory body of the South African government, established in 2000 by the ICASA Act to regulate both the telecommunications and broadcasting sectors in the public interest. Traditionally, telecommunications and broadcasting services operated separately and so has the regulation of the sectors. Broadcasting in South Africa was regulated by the Independent Broadcasting Authority (IBA), whereas telecommunications was regulated by the South African Telecommunications Regulatory Authority (SATRA). Rapid technological developments have led to the convergence of broadcasting and telecommunications services. This also had an influence on the convergence of regulation resulting in the merging of the IBA and SATRA. ICASA functions under the Department of Communications (DoC). It was initially composed of seven Council members. The ICASA amendment Act of 2006 included the Postal services, previously r ...

Northriding
North Riding is a suburb of Randburg, in Region C - formerly Johannesburg Region 5, South Africa. The suburb was named after one of the three historic subdivisions of Yorkshire. 'North' was favoured at the time due to North Riding's location north of the CBD of Johannesburg. The Suburb formerly fell under the jurisdiction of the Randburg Town Council before it was incorporated into the City of Johannesburg Metropolitan area. Of the original 3 farms that were joined to form Randburg, North riding was located on the Olievenhout farm. North Riding fully encloses the Suburb of Bellair Park. The area was once prominently known as a horse riding and stable stronghold in the north of Johannesburg, but gave way to other areas such as Kyalami and Honeydew extensions. This can be seen in the road and street names. Previously the area was rather rural, had Agricultural Holding status and is still referred to as Northriding A.H. by some. After 1996 North Riding developed rapidly, in bot ...

Johannesburg North, Gauteng
Johannesburg North is a suburb of Randburg, South Africa. It is located in Region C of the City of Johannesburg Metropolitan Municipality. Location It is divided in two by the Witkoppen Road and is situated halfway between Fourways Mall/Monte Casino to the east and Northgate Shopping Centre to the west on the northern outskirts of Randburg. History The suburb was largely formed during apartheid as White-Only subsidy housing for new families, but since the collapse of apartheid and the introduction of true democracy, the area has enjoyed a peaceful multi-cultural influx of new residents. The southern side is facing encroaching development of cluster homes, but in majority the houses in this area are free standing, middle income, family homes, with an average yard size of 1000 meters and containing single story homes.

Randpark Ridge
Randpark Ridge is an upmarket suburb of Randburg, South Africa. It is located in the Randburg region (region C) of the City of Johannesburg. It fell into the town of Randburg during the apartheid era. Developed in the early 1980s and still relatively new, Randpark Ridge is bordered by several other suburbs including Weltevreden Park, Sundowner, Boskruin, Bromhof, Honeydew and Fairland. It is located on the north-west extremity of Johannesburg. History The suburb has its origins as part of an old Witwatersrand farm called ''Boschkop'', named after the distinctive hill to north of the suburb, which is now the Boschkop Nature Reserve in the suburb of Boskruin. On this land, an old brick farm house was supposedly built on the land in around 1860. In 1903 the farm was owned by a J. Labuschagne and he sold part of the original land and farm house to John Dale Lace. He added on to the original Boer farmhouse; two gabled sections to either side, and a dam, built over the ''spruit'' ...

Fourways
The area referred to as Fourways (which is a collection of suburbs, including the traditional suburb of Fourways) is the fastest-developing commercial and residential hub in Sandton, north of Johannesburg, South Africa. The main access routes to Fourways are off the N1 at R511 William Nicol Drive, or alternatively along R564 Witkoppen Road. It is located mostly in Region E of the City of Johannesburg Metropolitan Municipality. It is roughly as far as one can go in the Johannesburg Metropolitan area before it dissolves into rolling hills, game farms and the capital Pretoria, 55 kilometres to the northeast. Hartebeespoort Dam and the Magaliesberg Mountains lie half an hour to the north-west. It is bordered by Bryanston to the east and south and Randburg to the west. The Fourways area is also home to the Fourways Mall which became the largest shopping centre in Africa post an extensive upgrade. Montecasino, which is a leisure and casino complex, is also located in the Fourways d ...

Randburg
Randburg is an area located in the Gauteng province of South Africa. Formerly a separate municipality, its administration devolved to the newly created City of Johannesburg Metropolitan Municipality, along with neighbouring Sandton and Roodepoort, in the late 1990s. During the transitional period of 1996–2000, Randburg was part of the Northern Metropolitan Local Council (MLC). History Randburg was founded as a town in 1959, as the amalgamation of 32 suburbs, northwest of Johannesburg. Although economically linked to Johannesburg, residents chose to create their own town council. The name ''Randburg'' was chosen in a competition, and is derived from the South African Rand currency, which was introduced at around the same time that the new municipality was established in 1959. Like other affluent northern suburbs of Johannesburg, the area was regarded as relatively liberal and elected Democratic Party members of parliament. As Apartheid ended, it became more supportive of F. W. d ...

Effective Radiated Power
Effective radiated power (ERP), synonymous with equivalent radiated power, is an IEEE standardized definition of directional radio frequency (RF) power, such as that emitted by a radio transmitter. It is the total power in watts that would have to be radiated by a half-wave dipole antenna to give the same radiation intensity (signal strength or power flux density in watts per square meter) as the actual source antenna at a distant receiver located in the direction of the antenna's strongest beam ( main lobe). ERP measures the combination of the power emitted by the transmitter and the ability of the antenna to direct that power in a given direction. It is equal to the input power to the antenna multiplied by the gain of the antenna. It is used in electronics and telecommunications, particularly in broadcasting to quantify the apparent power of a broadcasting station experienced by listeners in its reception area. An alternate parameter that measures the same thing is e ...
