Hertz
The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), often described as being equivalent to one event (or Cycle per second, cycle) per second. The hertz is an SI derived unit whose formal expression in terms of SI base units is 1/s or s−1, meaning that one hertz is one per second or the Inverse second, reciprocal of one second. It is used only in the case of periodic events. It is named after Heinrich Hertz, Heinrich Rudolf Hertz (1857–1894), the first person to provide conclusive proof of the existence of electromagnetic waves. For high frequencies, the unit is commonly expressed in metric prefix, multiples: kilohertz (kHz), megahertz (MHz), gigahertz (GHz), terahertz (THz). Some of the unit's most common uses are in the description of periodic waveforms and musical tones, particularly those used in radio- and audio-related applications. It is also used to describe the clock speeds at which computers and other electronics are driven. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
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 radio syndication, 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.

Northwestern United States
The Northwestern United States, also known as the American Northwest or simply the Northwest, is an informal geographic region of the United States. The region consistently includes the states of Oregon, Washington, Idaho, Montana and Wyoming. Some sources include Southeast Alaska in the Northwest. The related but distinct term Pacific Northwest generally excludes areas from the Rockies eastward, whereas the term " Inland Northwest" excludes areas west of the Cascades. The Northwestern United States is a subportion of the Western United States (which is, itself, even more ambiguous). In contrast, states included in the neighboring regions (Southwestern United States and Great Plains) and Utah are not simultaneously considered part of both regions. Like the southwestern United States, the Northwest definition has moved westward over time. The current area includes the old Oregon Territory (created in 1848–Oregon, Washington, Idaho, and areas in Montana west of the Conti ...

Western Canada
Western Canada, also referred to as the Western provinces, Canadian West, or Western provinces of Canada, and commonly known within Canada as the West, is a list of regions of Canada, Canadian region that includes the four western provinces and territories of Canada, provinces just north of the Canada–United States border namely (from west to east) British Columbia, Alberta, Saskatchewan and Manitoba. The people of the region are often referred to as "Western Canadians" or "Westerners", and though diverse from province to province are largely seen as being collectively distinct from other Canadians along cultural, linguistic, socioeconomic, geographic and political lines. They account for approximately 32% of Canada's total population. The region is further subdivided geographically and culturally between British Columbia, which is mostly on the western side of the Canadian Rockies and often referred to as the "British Columbia Coast, west coast", and the "Prairie Provinces" (c ...

Washington (state)
Washington, officially the State of Washington, is a U.S. state, state in the Pacific Northwest region of the United States. It is often referred to as Washington State to distinguish it from Washington, D.C., the national capital, both named after George Washington (the first President of the United States, U.S. president). Washington borders the Pacific Ocean to the west, Oregon to the south, Idaho to the east, and shares Canada–United States border, an international border with the Provinces and territories of Canada, Canadian province of British Columbia to the north. Olympia, Washington, Olympia is the List of capitals in the United States, state capital, and the most populous city is Seattle. Washington is the List of U.S. states and territories by area, 18th-largest state, with an area of , and the List of U.S. states and territories by population, 13th-most populous state, with a population of just less than 8 million.

Richmond, British Columbia
Richmond is a city in the coastal Lower Mainland region of British Columbia, Canada. Mainly a suburban city, it occupies almost the entirety of Lulu Island (excluding Queensborough, New Westminster, Queensborough), between the two estuarine distributaries of the Fraser River. Encompassing the adjacent Sea Island (British Columbia), Sea Island (where the Vancouver International Airport is located) and several other smaller islands and uninhabited islets to its north and south, the suburb neighbours Vancouver and Burnaby on the Burrard Peninsula to the north, New Westminster and Annacis Island to the east, Delta, British Columbia, Delta to the south, and the Strait of Georgia to the west. The indigenous Coast Salish peoples were the first people to inhabit the area of modern-day Richmond, with the Musqueam Indian Band, Musqueam Band naming the site near Terra Nova "" or "boiling point". Today, East Asian Canadians make up a majority of Richmond's population, along with the Contine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Lulu Island
Lulu Island is the name of the largest island in the estuary of the Fraser River, located south of Vancouver, British Columbia, Canada, and the List of Canadian islands by population, second-most populous island in British Columbia, after Vancouver Island. The city of Richmond, British Columbia, Richmond occupies most of the island, while a small section at the eastern tip, known as Queensborough, New Westminster, Queensborough, is part of the city of New Westminster. Lulu Island is situated between the two principal arms of the Fraser River estuary across and downstream from the City of New Westminster. The middle arm of the Fraser River separates it on the northwest from Sea Island (British Columbia), Sea Island, the site of Vancouver International Airport, which, despite its name, is also part of the City of Richmond, and Swishwash Island and Iona Island (British Columbia), Iona Island.

Transmitter
In electronics and telecommunications, a radio transmitter or just transmitter (often abbreviated as XMTR or TX in technical documents) is an electronic device which produces radio waves with an antenna (radio), antenna with the purpose of signal transmission to a radio receiver. 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 Electromagnetic radiation, radiates radio waves. Transmitters are necessary component parts of all electronic devices that communicate by radio communication, radio, such as radio broadcasting, radio (audio) 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 fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
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 * Junglins ...

Directional Antenna
A directional antenna or beam antenna is an antenna that radiates or receives greater radio wave power in specific directions. Directional antennas can radiate radio waves in beams, when greater concentration of radiation in a certain direction is desired, or in receiving antennas receive radio waves from one specific direction only. This can increase the power transmitted to receivers in that direction, or reduce interference from unwanted sources. This contrasts with omnidirectional antennas such as dipole antennas which radiate radio waves over a wide angle, or receive from a wide angle. The extent to which an antenna's angular distribution of radiated power, its radiation pattern, is concentrated in one direction is measured by a parameter called antenna gain. A high-gain antenna (HGA) is a directional antenna with a focused, narrow beam width, permitting more precise targeting of the radio signals. Most commonly referred to during space missions, these antennas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Clear-channel Station
A clear-channel station is a North American AM radio station that has the highest level of protection from interference from other stations, particularly from nighttime skywave signals. This classification 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 the 1983 adoption of the Regional Agreement for the Medium Frequency Broadcasting Service in Region 2 (Rio Agreement), 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 a transmitter power output ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
List Of North American Broadcast Station Classes
This is a list of broadcast station classes applicable in much of North America under international agreements between the United States, Canada and Mexico. Effective radiated power (ERP) and height above average terrain (HAAT) are listed unless otherwise noted. All radio and television stations within of the US-Canada or US-Mexico border must get approval by both the domestic and foreign agency. These agencies are Industry Canada/ Canadian Radio-television and Telecommunications Commission (CRTC) in Canada, the Federal Communications Commission (FCC) in the US, and the Federal Telecommunications Institute (IFT) in Mexico. AM Station class descriptions All domestic (United States) AM stations are classified as A, B, C, or D. * A (formerly I) — clear-channel stations — 10 kW to 50 kW, 24 hours. **Class A stations are only protected within a radius of the transmitter site. **The old Class I was divided into three: Class I-A, I-B and I-N.
