Troy University Public Radio
Troy Public Radio is a network of public radio stations based in Troy, Alabama, United States, that serve southeastern Alabama and parts of western Georgia and northwestern Florida with classical music, folk music, and jazz programs, as well as news and feature programs from the National Public Radio, Public Radio Exchange, and American Public Media networks. The stations are licensed to Troy University, on whose main campus the studios are located. History WTSU-FM started broadcasting on March 1, 1977 as the state's third public radio station (the callsign stands for the university's name then, "Troy State University,"), and the first south of Birmingham. WTSU originally broadcast at 90.1 MHz with a power of 50,000 watts; by 1981, it moved to its present frequency of 89.9, doubling its wattage to 100,000. Programming from the start was a blend of NPR news and classical music, combined with an automated block of "beautiful music" between 9:00 a.m. and 4:00 p.m. T ...

Troy, Alabama
Troy is a city in and the county seat of Pike County, Alabama, United States. It was formally incorporated on February 4, 1843. Between 1763 and 1783, the area where Troy sits was part of the colony of British West Florida.The Economy of British West Florida, 1763–1783 by Robin F. A. Fabel (University of Alabama Press, 2002) After 1783, the region fell under the jurisdiction of the newly created United States of America. As of the 2010 census, its population was 18,033. The 2019 estimated population was 18,957. The City of Troy is considered one of the fastest-growing cities in Alabama. Troy is home to Troy University, the fourth-largest university in total enrollment in Alabama. History Before the Civil War For many centuries, the area around Troy was settled by different tribes of Native Americans, but became primarily known for its Muskogee Creek presence. Most Creek tribes lived along rivers or streams at that time. Near the Troy area, many Native American ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Classical 24
Classical 24 is a syndicated, satellite-delivered public radio service providing classical music to its carrying stations. It generally airs overnights on many non-commercial and a handful of commercial classical music stations. However, the service is operated 24 hours a day and is used by some stations during the day to augment their schedules. It was co-created by a partnership between Minnesota Public Radio and Public Radio International to fulfill the need for a comprehensive classic music service for stations to supplement their schedules. As part of this partnership, the service is produced by American Public Media and since 2018, is distributed by Public Radio Exchange. It began operation on December 1, 1995. Unlike most mainstream classical music stations, Classical 24 adheres to a "clock" that typically consists of one or two short selections at the beginning of the hour, followed by a longer work such as a symphony, and then a short piece or two to close the hour. ...

Foot (unit)
The foot ( feet), standard symbol: ft, is a unit of length in the British imperial and United States customary systems of measurement. The prime symbol, , is a customarily used alternative symbol. Since the International Yard and Pound Agreement of 1959, one foot is defined as 0.3048 meters exactly. In both customary and imperial units, one foot comprises 12 inches and one yard comprises three feet. Historically the "foot" was a part of many local systems of units, including the Greek, Roman, Chinese, French, and English systems. It varied in length from country to country, from city to city, and sometimes from trade to trade. Its length was usually between 250 mm and 335 mm and was generally, but not always, subdivided into 12 inches or 16 digits. The United States is the only industrialized nation that uses the international foot and the survey foot (a customary unit of length) in preference to the meter in its commercial, e ...

Metre
The metre (British spelling) or meter (American spelling; see spelling differences) (from the French unit , from the Greek noun , "measure"), symbol m, is the primary unit of length in the International System of Units (SI), though its prefixed forms are also used relatively frequently. The metre was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole along a great circle, so the Earth's circumference is approximately km. In 1799, the metre was redefined in terms of a prototype metre bar (the actual bar used was changed in 1889). In 1960, the metre was redefined in terms of a certain number of wavelengths of a certain emission line of krypton-86. The current definition was adopted in 1983 and modified slightly in 2002 to clarify that the metre is a measure of proper length. From 1983 until 2019, the metre was formally defined as the length of the path travelled by light in a vacuum in of a second. After the 2019 redefiniti ...

Height Above Average Terrain
Height above average terrain (HAAT), or (less popularly) effective height above average terrain (EHAAT), is the vertical position of an antenna site is above the surrounding landscape. HAAT is used extensively in FM radio and television, as it is more important than effective radiated power (ERP) in determining the range of broadcasts (VHF and UHF in particular, as they are line of sight transmissions). For international coordination, it is officially measured in meters, even by the Federal Communications Commission in the United States, as Canada and Mexico have extensive border zones where stations can be received on either side of the international boundaries. Stations that want to increase above a certain HAAT must reduce their power accordingly, based on the maximum distance their station class is allowed to cover (see List of North American broadcast station classes for more information on this). The FCC procedure to calculate HAAT is: from the proposed or actual antenna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical cir ...

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 ef ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Facility ID
The facility ID number, also called a FIN or facility identifier, is a unique integer number of one to six digits, assigned by the U.S. Federal Communications Commission (FCC) Media Bureau to each broadcast station in the FCC Consolidated Database System (CDBS) and Licensing and Management System (LMS) databases, among others. Because CDBS includes information about foreign stations which are notified to the U.S. under the terms of international frequency coordination agreements, FINs are also assigned to affected foreign stations. However, this has no legal significance, and the numbers are not used by the regulatory authorities in those other countries. Current FCC practice is to assign facility ID numbers sequentially, but this is not an official requirement, so third-party users must not rely on it. Unlike call signs, however, the FIN associated with a particular station never changes; thus, the FCC staff and interested parties can be certain to which station an application ...

City Of License
In American, Canadian, and Mexican broadcasting, a city of license or community of license is the community that a radio station or television station is officially licensed to serve by that country's broadcast regulator. In North American broadcast law, the concept of ''community of license'' dates to the early days of AM radio broadcasting. The requirement that a broadcasting station operate a ''main studio'' within a prescribed distance of the community which the station is licensed to serve appears in U.S. law as early as 1939. Various specific obligations have been applied to broadcasters by governments to fulfill public policy objectives of broadcast localism, both in radio and later also in television, based on the legislative presumption that a broadcaster fills a similar role to that held by community newspaper publishers. United States In the United States, the Communications Act of 1934 requires that "the Commission shall make such distribution of licenses, f ...
