CBTL-FM
CBT-FM is a public radio station in Grand Falls-Windsor, Newfoundland and Labrador, Canada owned by the Canadian Broadcasting Corporation and broadcasting the CBC Radio One news and information network. An AM station for many decades, in 2022, CBT transitioned to FM broadcasting on 93.3 MHz with an effective radiated power of 100,000 watts from a transmitter near the town of Northern Arm. Four FM re-broadcasters provide additional coverage. History CBT launched in 1949 on 1350 kHz after the Broadcasting Corporation of Newfoundland, the pre-Confederation public broadcaster, was absorbed by the CBC when Newfoundland joined Canada. The frequency was changed to 990 kHz in 1956, and then to 540 kHz in 1963 (with 990 being reassigned to CBY in Corner Brook). On 540 kHz, CBT transmitted with 10,000 watts using a non-directional antenna. It was a Class A station broadcasting on a Canadian and Mexican clear channel frequency from a transmitter on Crawley Avenue in Grand Falls-Wind ...

All-news Radio
All-news radio is a radio format devoted entirely to the discussion and broadcast of news. All-news radio is available in both local and syndicated forms, and is carried on both major US satellite radio networks. All-news stations can run the gamut from simulcasting an all-news television station like CNN, to a "rip and read" headline service, to stations that include live coverage of news events and long-form public affairs programming. Many stations brand themselves ''Newsradio'' but only run news during the morning and afternoon drive times, or in some cases, broadcast talk radio shows with frequent news updates. These stations are properly labeled as "news/talk" stations. Also, some National Public Radio stations identify themselves as ''News and Information'' stations, which means that in addition to running the NPR news magazines such as ''Morning Edition'' and ''All Things Considered'', they run other information and public affairs programs.

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 effec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canadian Radio-television And Telecommunications Commission
The Canadian Radio-television and Telecommunications Commission (CRTC; french: Conseil de la radiodiffusion et des télécommunications canadiennes, links=) is a public organization in Canada with mandate as a regulatory agency for broadcasting and telecommunications. It was created in 1976 when it took over responsibility for regulating telecommunication carriers. Prior to 1976, it was known as the Canadian Radio and Television Commission, which was established in 1968 by the Parliament of Canada to replace the Board of Broadcast Governors. Its headquarters is located in the Central Building (Édifice central) of Les Terrasses de la Chaudière in Gatineau, Quebec. History The CRTC was originally known as the Canadian Radio-Television Commission. In 1976, jurisdiction over telecommunications services, most of which were then delivered by monopoly common carriers (for example, telephone companies), was transferred to it from the Canadian Transport Commission although the abbrev ...

Transmitter
In electronics and telecommunications, a radio transmitter or just transmitter is an electronic device which produces radio waves with an antenna (radio), antenna. The transmitter itself generates a radio frequency alternating current, which is applied to the Antenna (radio), 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 communication, radio, such as radio broadcasting, radio and television broadcasting stations, cell phones, walkie-talkies, Wireless LAN, 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 engineering, communication purposes; or radiolocation, such as radar and navigational transmitters. Generators of radio waves for heatin ... [...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 Bahamas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Omnidirectional Antenna
In radio communication, an omnidirectional antenna is a class of antenna which radiates equal radio power in all directions perpendicular to an axis (azimuthal directions), with power varying with angle to the axis (elevation angle), declining to zero on the axis. When graphed in three dimensions ''(see graph)'' this radiation pattern is often described as ''doughnut-shaped''. Note that this is different from an isotropic antenna, which radiates equal power in ''all'' directions, having a ''spherical'' radiation pattern. Omnidirectional antennas oriented vertically are widely used for nondirectional antennas on the surface of the Earth because they radiate equally in all horizontal directions, while the power radiated drops off with elevation angle so little radio energy is aimed into the sky or down toward the earth and wasted. Omnidirectional antennas are widely used for radio broadcasting antennas, and in mobile devices that use radio such as cell phones, FM radios, walkie ...

Canadian Confederation
Canadian Confederation (french: Confédération canadienne, link=no) was the process by which three British North American provinces, the Province of Canada, Nova Scotia, and New Brunswick, were united into one federation called the Canada, Dominion of Canada, on July 1, 1867. Upon Confederation, Canada consisted of four provinces: Ontario and Quebec, which had been split out from the Province of Canada, and the provinces of Nova Scotia and New Brunswick. Over the years since Confederation, Canada has seen numerous territorial changes and expansions, resulting in the current number of Provinces and territories of Canada, ten provinces and three territories. Terminology Canada is a federation and not a confederate association of sovereign states, which is what "confederation" means in contemporary political theory. It is nevertheless often considered to be among the world's more decentralization, decentralized federations. The use of the term ''confederation'' arose in the Provin ...
