CJOB (AM)
CJOB (680 kHz) is a commercial AM radio station in Winnipeg, Manitoba, Canada. It is owned and operated by Corus Radio and airs a news/ talk format with news and sports programs. CJOB and its sister stations, CFPG-FM, CJKR-FM, and CKND-DT, have studios and offices at 201 Portage in Winnipeg. The transmitter tower array is located off Floodway Road near Saint Adolphe. CJOB operates at 50,000 watts (the highest power permitted for Canadian AM stations), but because 680 kHz is a clear channel frequency, CJOB must use a directional antenna at all times to avoid interfering with other stations. Even with this restriction, CJOB's low frequency, transmitter power, and Manitoba's mostly flat land (with near-perfect ground conductivity) allows it to reach almost all of Manitoba during the day. Programming CJOB airs local talk shows during the day, with news-intensive segments during AM and PM drive time. Evenings, CJOB has a sports talk show, and at night, CJOB carries two nat ...

Radio Station
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).

Drive Time
Drive time is the daypart in which radio broadcasters can reach the most people who listen to car radios while driving, usually to and from work, or on public transportation. Drive-time periods are when the number of radio listeners in this class is at its peak and, thus, commercial radio can generate the most revenue from advertising. Drive time usually coincides with rush hour. Content Mainstream stations employ high-status presenters for drive time shows. In the United States, popular national hosts who are associated with morning drive include Howard Stern, Ryan Seacrest and Steve Inskeep, while Sean Hannity is associated with afternoon drive on the East Coast. Drive time often includes a heavier run of traffic reports, for which many stations employ their own helicopters or hire a third-party traffic reporting service. For popular music-oriented stations, morning drive-time is typically dominated by the " morning zoo" genre of radio program, with the afternoon portion ...

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] |
Clear Channel Station
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] |
Saint Adolphe, Manitoba
St. Adolphe, or Saint Adolphe, originally called Pointe-Coupée, is a community in the Rural Municipality of Ritchot, Manitoba, Canada. It is located along the east bank of the Red River, approximately south of Winnipeg. It was named after Adolphe Turner, who made a large donation to the local church. St. Adolphe is notable for being home to the world's largest snow maze. The community is surrounded by a dike as a result of several devastating floods, it was raised to levels above the 1997 Red River flood, which was the last major flood to inundate the town and area. History The area was first settled by the Métis before 1812. They were joined by others who came after the merger of the Hudson's Bay Company and the North West Company and residents from the Red River Colony who arrived after the floods of 1826 and 1852. In 1857, the Parish of St. Norbert was founded which encompassed the then settlements of Pointe-Coupée (now St. Adolphe) and Point-à-Grouette (now Ste. A ...

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 ...

Transmitter
In electronics and telecommunications, a radio transmitter or just transmitter is an electronic device which produces radio waves with an antenna. The transmitter itself generates a radio frequency alternating current, which is applied to the antenna. When excited by this alternating current, the antenna radiates radio waves. Transmitters are necessary component parts of all electronic devices that communicate by radio, such as radio and television broadcasting stations, cell phones, walkie-talkies, wireless computer networks, Bluetooth enabled devices, garage door openers, two-way radios in aircraft, ships, spacecraft, radar sets and navigational beacons. The term ''transmitter'' is usually limited to equipment that generates radio waves for communication purposes; or radiolocation, such as radar and navigational transmitters. Generators of radio waves for heating or industrial purposes, such as microwave ovens or diathermy equipment, are not usually called transmitter ...

201 Portage
201 Portage (formerly TD Centre, Canwest Place, and CanWest Global Place) is an office tower at the northwest intersection of Portage and Main in Winnipeg, Manitoba, Canada. It is the 2nd tallest building in Winnipeg and in the province of Manitoba. History Announced as TD Centre in November 1987, the 33-storey building was constructed between 1988 and 1990 by the Toronto Dominion Bank for $38,000,000. The construction of 201 Portage required the demolition of the Childs Building (also known as the McArthur Building) at 211 Portage. When the Childs Building was constructed in 1909, it was the tallest building in Winnipeg. The Childs Building had been 12 storeys above ground, and tall. A smaller twin building was planned but never built. Originally built by the Toronto Dominion Bank, the skyscraper was acquired by Canwest to serve as the company's main corporate headquarters. Global Winnipeg ( CKND-DT) moved its operations to 201 Portage on September 1, 2008. Having declare ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sister Station
In broadcasting, sister stations or sister channels are radio or television stations operated by the same company, either by direct ownership or through a management agreement. Radio sister stations will often have different formats, and sometimes one station is on the AM band while another is on the FM band. Conversely, several types of sister-station relationships exist in television; stations in the same city will usually be affiliated with different television networks (often one with a major network and the other with a secondary network), and may occasionally shift television programs between each other when local events require one station to interrupt its network feed. Sister stations in separate (but often nearby) cities owned by the same company may or may not share a network affiliation. For example, WNYW and WWOR-TV, in New York City and Secaucus, New Jersey, are both owned by Fox Corporation. WNYW is a Fox owned-and-operated station; WWOR-TV is a MyNetworkTV o ...

Radio Format
A radio format or programming format (not to be confused with broadcast programming) describes the overall content broadcast on a radio station. The radio format emerged mainly in the United States in the 1950s, at a time when radio was compelled to develop new and exclusive ways to programming by competition with television. The formula has since spread as a reference for commercial radio programming worldwide. A radio format aims to reach a more or less specific audience according to a certain type of programming, which can be thematic or general, more informative or more musical, among other possibilities. Radio formats are often used as a marketing tool and are subject to frequent changes. Except for talk radio or sports radio formats, most programming formats are based on commercial music. However the term also includes the news, bulletins, DJ talk, jingles, commercials, competitions, traffic news, sports, weather and community announcements between the tracks. Background ...
