CHIN (AM)
CHIN (1540 kHz) is a commercial AM radio station in Toronto, Ontario, Canada. It is owned by CHIN Radio/TV International, and broadcasts a multilingual radio format, with programs in Mandarin, Cantonese, Portuguese and other languages. It also has an FM rebroadcaster at 91.9 MHz, CHIN-1-FM, originally used to fill in reception gaps in parts of Greater Toronto. But CHIN-1-FM now broadcasts a separate schedule of ethnic programming, no longer simulcasting CHIN 1540 AM. In addition, there is a full-power FM station on 100.7 MHz, CHIN-FM, which offers a third ethnic programme schedule. CHIN, CHIN-1-FM and CHIN-FM have their radio studios on College Street in the Palmerston-Little Italy neighbourhood of Toronto. By day, CHIN 1540 broadcasts at 50,000 watts, the maximum power for Canadian AM stations. But because 1540 AM is a clear-channel frequency reserved for the U.S. and Bahamas, CHIN reduces power at night to 30,000 watts to avoid interference. It uses a directional ...

Toronto
Toronto ( ; or ) is the capital city of the Canadian province of Ontario. With a recorded population of 2,794,356 in 2021, it is the most populous city in Canada and the fourth most populous city in North America. The city is the anchor of the Golden Horseshoe, an urban agglomeration of 9,765,188 people (as of 2021) surrounding the western end of Lake Ontario, while the Greater Toronto Area proper had a 2021 population of 6,712,341. Toronto is an international centre of business, finance, arts, sports and culture, and is recognized as one of the most multicultural and cosmopolitan cities in the world. Indigenous peoples have travelled through and inhabited the Toronto area, located on a broad sloping plateau interspersed with rivers, deep ravines, and urban forest, for more than 10,000 years. After the broadly disputed Toronto Purchase, when the Mississauga surrendered the area to the British Crown, the British established the town of York in 1793 and later d ...

Mandarin Chinese
Mandarin (; ) is a group of Chinese (Sinitic) dialects that are natively spoken across most of northern and southwestern China. The group includes the Beijing dialect, the basis of the phonology of Standard Chinese, the official language of China. Because Mandarin originated in North China and most Mandarin dialects are found in the north, the group is sometimes referred to as Northern Chinese (). Many varieties of Mandarin, such as those of the Southwest (including Sichuanese) and the Lower Yangtze, are not mutually intelligible with the standard language (or are only partially intelligible). Nevertheless, Mandarin as a group is often placed first in lists of languages by number of native speakers (with nearly one billion). Mandarin is by far the largest of the seven or ten Chinese dialect groups; it is spoken by 70 percent of all Chinese speakers over a large geographical area that stretches from Yunnan in the southwest to Xinjiang in the northwest and Heilongji ...

Tower Array
A tower array is an arrangement of multiple radio towers which are mast radiators in a phased array. They were originally developed as ground-based tracking radars. Tower arrays can consist of free-standing or guyed towers or a mix of them. Tower arrays are used to constitute a directional antenna of a mediumwave or longwave radio station. The number of towers in a tower array can vary. In many arrays all towers have the same height, but there are also arrays of towers of different height. The arrangement can vary. For directional antennas with fixed radiation pattern, linear arrangements are preferred, while for switchable directional patterns (usually for daytime groundwave versus nighttime skywave), square arrangements are chosen. Examples Tower arrays with guyed masts * Longwave transmitter Europe 1 * Transmitter Weisskirchen * Beidweiler Longwave Transmitter * Transmitter Wachenbrunn * Transmitter Ismaning (VoA-Station) Tower arrays with free standing towers * Junglinste ...

Directional Antenna
A directional antenna or beam antenna is an antenna which radiates or receives greater power in specific directions allowing increased performance and reduced interference from unwanted sources. Directional antennas provide increased performance over dipole antennas—or omnidirectional antennas in general—when greater concentration of radiation in a certain direction is desired. A high-gain antenna (HGA) is a directional antenna with a focused, narrow radiowave beam width, permitting more precise targeting of the radio signals. Most commonly referred to during space missions, these antennas are also in use all over Earth, most successfully in flat, open areas where there are no mountains to disrupt radiowaves. By contrast, a low-gain antenna (LGA) is an omnidirectional antenna with a broad radiowave beam width, that allows the signal to propagate reasonably well even in mountainous regions and is thus more reliable regardless of terrain. Low-gain antennas are often used i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bahamas
The Bahamas (), officially the Commonwealth of The Bahamas, is an island country within the Lucayan Archipelago of the West Indies in the North Atlantic. It takes up 97% of the Lucayan Archipelago's land area and is home to 88% of the archipelago's population. The archipelagic state consists of more than 3,000 islands, cays, and islets in the Atlantic Ocean, and is located north of Cuba and northwest of the island of Hispaniola (split between the Dominican Republic and Haiti) and the Turks and Caicos Islands, southeast of the U.S. state of Florida, and east of the Florida Keys. The capital is Nassau on the island of New Providence. The Royal Bahamas Defence Force describes The Bahamas' territory as encompassing of ocean space. The Bahama Islands were inhabited by the Lucayans, a branch of the Arawakan- speaking Taíno, for many centuries. Christopher Columbus was the first European to see the islands, making his first landfall in the "New World" in 1492 when h ...

Clear-channel
A clear-channel station is an AM radio station in North America that has the highest protection from interference from other stations, particularly concerning night-time skywave propagation. The system exists to ensure the viability of cross-country or cross-continent radio service enforced through a series of treaties and statutory laws. Known as Class A stations since 1982, they are occasionally still referred to by their former classifications of Class I-A (the highest classification), Class I-B (the next highest class), or Class I-N (for stations in Alaska too far away to cause interference to the primary clear-channel stations in the lower 48 states). The term "clear-channel" is used most often in the context of North America and the Caribbean, where the concept originated. Since 1941, these stations have been required to maintain an effective radiated power of at least 10,000 watts to retain their status. Nearly all such stations in the United States, Canada and The Bahama ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Palmerston-Little Italy
Palmerston-Little Italy is a neighbourhood in central Toronto, Ontario, Canada. Its boundaries, according to the City of Toronto, are by Bathurst Street, Toronto, Bathurst Street to the east, Bloor Street to the north, Dovercourt Road to the west and College Street (Toronto), College Street to the south. It is a mature downtown neighbourhood. Within this official neighbourhood of the City of Toronto are two neighbourhoods, Palmerston and Little Italy, Toronto, Little Italy and the commercial enclave of Mirvish Village. History In the 1950s and 1960s, the Ontario provincial and Metropolitan Toronto governments proposed running a six-lane north–south expressway to the east of Grace Street. This was an extension of Ontario Highway 400, Highway 400 and would have gone from a proposed Crosstown Expressway (Toronto), Crosstown Expressway in the vicinity of Davenport and Dupont, south to the Gardiner Expressway. In the 1960s, opposition to the Spadina, Crosstown and Christie expressway ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
College Street (Toronto)
College Street is a principal arterial thoroughfare in downtown Toronto, Canada, connecting former streetcar suburbs in the west with the city centre. The street is home to an ethnically diverse population in the western residential reaches, and institutions like the Ontario Legislature and the University of Toronto in the downtown core. At Yonge Street, College continues to the east as Carlton Street. History College Street takes its name from the University of Toronto, originally King's College. Between Spadina Avenue and Yonge Street, College marks the southern boundary of the original 1827 land grant for the college. The street was immediately proposed as an east-west route along the boundary, although the section was not built until 1859. The first section built was to the west of Spadina Avenue, through the estate of Robert Baldwin, who laid out the route. This section was built with the that was also used for Spadina. The section through Baldwin's estate was laid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Studio
A recording studio is a specialized facility for sound recording, mixing, and audio production of instrumental or vocal musical performances, spoken words, and other sounds. They range in size from a small in-home project studio large enough to record a single singer-guitarist, to a large building with space for a full orchestra of 100 or more musicians. Ideally, both the recording and monitoring (listening and mixing) spaces are specially designed by an acoustician or audio engineer to achieve optimum acoustic properties (acoustic isolation or diffusion or absorption of reflected sound echoes that could otherwise interfere with the sound heard by the listener). Recording studios may be used to record singers, instrumental musicians (e.g., electric guitar, piano, saxophone, or ensembles such as orchestras), voice-over artists for advertisements or dialogue replacement in film, television, or animation, foley, or to record their accompanying musical soundtracks.

Simulcast
Simulcast (a portmanteau of simultaneous broadcast) is the broadcasting of programmes/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. Early radio simulcasts Before launching stereo radio, experiments were conducted by transmitting left and right channels on different radio channels. The earliest record found was a broadcast by the BBC in 1926 of a Halle Orchestra concert from Manchester, using the wavelengths of the regional stations and Daventry. In its earliest days the BBC often tran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rebroadcaster
A broadcast relay station, also known as a satellite station, relay transmitter, broadcast translator (U.S.), re-broadcaster (Canada), repeater (two-way radio) or complementary station (Mexico), is a broadcast transmitter which repeats (or transponds) the signal of a radio or television station to an area not covered by the originating station. It expands the broadcast range of a television or radio station beyond the primary signal's original coverage or improves service in the original coverage area. The stations may be (but are not usually) used to create a single-frequency network. They may also be used by an AM or FM radio station to establish a presence on the other band. Relay stations are most commonly established and operated by the same organisations responsible for the originating stations they repeat. However, depending on technical and regulatory restrictions, relays may also be set up by unrelated organisations. Types Broadcast translators In its simplest form ...
