WQUB
WQUB (90.3 FM) is a 28,000 watt effective radiated power radio station in Quincy, Illinois, in western Illinois along the Mississippi River. This station provides primary coverage for nine counties in the western Illinois and northeastern Missouri region. It is owned by the University of Missouri St. Louis and serves as a semi-satellite of KWMU in St. Louis. History WQUB began in 1948 as WWQC, a carrier current on the campus of Quincy University, then known as Quincy College. In 1974, the college was granted a full license for a 10-watt station which went on the air in 1979. Its coverage area was effectively limited to the area around Francis Hall on campus. In 1983, power was boosted to 100 watts, enough to cover the campus. The response was strong enough that the school began an effort to upgrade the station, culminating in becoming a full NPR member in 1988, not long after the school won university status. Power was also increased to 10,000 watts. The station increa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Public Radio
Public broadcasting (or public service broadcasting) is radio, television, and other electronic media outlets whose primary mission is public service with a commitment to avoiding political and commercial influence. Public broadcasters receive funding from diverse sources including license fees, individual contributions and donations, public financing, and corporate underwriting. A public service broadcaster should operate as a non-partisan, non-profit entity, guided by a clear public interest mandate. PSBs must be safeguarded from external interference—especially of a political or commercial nature—in matters related to governance, budgeting, and editorial decision-making. The PSB model relies on an independent and transparent system of governance, encompassing key areas such as editorial policy, managerial appointments, and financial oversight. Common media include AM, FM, and shortwave radio; television; and the Internet. Public broadcasting may be nationally or loc ...

Digital Subchannel
In broadcasting, digital subchannels are a method of transmitting more than one independent program stream simultaneously from the same digital radio or television station on the same radio frequency channel. This is done by using data compression techniques to reduce the size of each individual program stream, and multiplexing to combine them into a single signal. The practice is sometimes called " multicasting". ATSC television United States The ATSC digital television standard used in the United States supports multiple program streams over-the-air, allowing television stations to transmit one or more subchannels over a single digital signal. A virtual channel numbering scheme distinguishes broadcast subchannels by appending the television channel number with a period digit (".xx"). Simultaneously, the suffix indicates that a television station offers additional programming streams. By convention, the suffix position ".1" is normally used to refer to the station's main d ...

HD Radio
HD Radio (HDR) is a trademark for in-band on-channel (IBOC) digital radio broadcast technology. HD radio generally simulcast, simulcasts an existing analog radio station in digital format with less noise and with additional text information. HD Radio is used primarily by FM broadcasting, FM radio stations in the United States, U.S. Virgin Islands, Canada, Mexico and the Philippines, with a few implementations outside North America. HD Radio transmits the digital signals in unused portions of the same band as the analog AM and FM signals. As a result, radios are more easily designed to pick up both signals, which is why the HD in HD Radio is sometimes referred to stand for "hybrid digital", not "high definition". Officially, HD is not intended to stand for any term in HD Radio, it is simply part of iBiquity's trademark, and does not have any meaning on its own. HD Radios tune into the station's analog signal first and then look for a digital signal. The European DRM system shares c ...

Radio Masts And Towers
Radio masts and towers are typically tall structures designed to support antenna (radio), antennas for telecommunications and broadcasting, including television. There are two main types: guyed and self-supporting structures. They are among the tallest human-made structures. Masts are often named after the broadcasting organizations that originally built them or currently use them. A mast radiator or radiating tower is one in which the metal mast or tower itself is energized and functions as the transmitting antenna. Terminology The terms "mast" and "tower" are often used interchangeably. However, in structural engineering terms, a tower is a self-supporting or cantilevered structure, while a Guyed mast, mast is held up by stays or guy-wires. ; A ''mast'': is a guyed mast, a thin structure without the shear strength to stand unsupported, that uses attached guy lines for stability. They may be mounted on the ground or on top of buildings. Typical ''masts'' are of steel latt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shrewsbury, Missouri
Shrewsbury is an inner-ring suburb of St. Louis, located in St. Louis County, Missouri, United States. The population was 6,254 at the 2010 census. History Shrewsbury was officially platted in 1889. The land which became Shrewsbury originally belonged to Gregorie Sarpy and Charles Gratiot Sr.; by 1890, it was divided into farms and sold to families. The area now known as Shrewsbury was a farm owned by General John Murdoch. The Murdoch farm was called Shrewsbury Park, named after a town in England. In 1913, concerned resident Joseph Burge organized the Shrewsbury Improvement Association to improve Shrewsbury and develop its first sewer system. Shrewsbury was incorporated and became a village in 1913; shortly thereafter a sanitation system was established, reducing water-borne diseases prevalent at the time. In 1938, the United States government offered financial aid to the city of Shrewsbury, and land was acquired for the construction of a new city hall replacing the 1912 ori ...

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