WERC (AM)
WERC (960 kHz) is a commercial AM radio station licensed to Birmingham, Alabama. It is owned by iHeartMedia and it simulcasts a talk radio format with sister station 105.5 WERC-FM. The studios and offices are in Beacon Ridge Tower on First Avenue South in Birmingham, off Interstate 65. WERC transmits with 5,000 watts. By day, the signal is non-directional, but to protect other stations on 960 AM from interference, at night it uses a directional antenna with a two-tower array. The transmitter is off Arkadelphia Road near Interstate 20 in Birmingham. Programming WERC was the first station in Birmingham to carry an all-talk format. Weekdays begin with a local news and interview show, "Alabama's Morning News with JT and Leah." The rest of the weekday schedule is nationally syndicated shows, largely from co-owned Premiere Networks: "The Glenn Beck Program," "The Clay Travis and Buck Sexton Show," "The Sean Hannity Show," " The Michael Berry Show," "The Jesse Kelly Show," "Coa ...

AM Broadcasting
AM broadcasting is radio broadcasting using amplitude modulation (AM) transmissions. It was the first method developed for making audio radio transmissions, and is still used worldwide, primarily for medium wave (also known as "AM band") transmissions, but also on the longwave and shortwave radio bands. The earliest experimental AM transmissions began in the early 1900s. However, widespread AM broadcasting was not established until the 1920s, following the development of vacuum tube receivers and transmitters. AM radio remained the dominant method of broadcasting for the next 30 years, a period called the "Golden Age of Radio", until television broadcasting became widespread in the 1950s and received most of the programming previously carried by radio. Subsequently, AM radio's audiences have also greatly shrunk due to competition from FM (FM broadcasting, frequency modulation) radio, Digital audio broadcasting, Digital Audio Broadcasting (DAB), satellite radio, HD Radio, HD (digi ...

Interstate 20 In Alabama
In Alabama, Interstate 20 (I-20) travels through the center of the state. It enters the state from Mississippi near Cuba, and travels northeastward through Tuscaloosa and Birmingham. At Birmingham, I-20 turns eastward and heads through Oxford before crossing the Georgia state line near Lebanon. Other cities on the route include Livingston, Bessemer, and Pell City. For approximately , more than half its distance within the state, I-20 is concurrent with I-59 from the Mississippi state line to eastern Birmingham near Birmingham–Shuttlesworth International Airport. Mileage and exits on the concurrency are I-59's, although both highways have the same mileage for the Alabama concurrency. Route description Western Alabama After I-20/I-59 enters Alabama from Mississippi, they travel concurrently northeastward across the Tombigbee River and Black Warrior River delta country which is generally low-lying farmland until reaching Tuscaloosa. This area contains low population. U.S. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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 * Junglinster L ...

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 in ... [...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 ...

Interstate 65 In Alabama
Interstate 65 (I-65) meanders across of the Alabama countryside linking six of the state's 10 largest cities. The highway links together many important roadways that make commerce inside and outside of the state's boundaries possible. It starts at Interstate 10 in Alabama, I-10 near Mobile, Alabama, Mobile. The route passes through the major cities of Montgomery, Alabama, Montgomery, Birmingham, Alabama, Birmingham, and Decatur, Alabama, Decatur before entering Tennessee in the north near the town of Ardmore, Alabama. The entire Alabama portion of I-65 is dedicated as Heroes Highway in honor of Central Intelligence Agency officer Johnny Micheal Spann and all of the people who died during the September 11 attacks. Route description I-65 starts its northward journey in Mobile as a three-lane freeway at a directional Y interchange with Interstate 10 in Alabama, I-10 not far from the Gulf of Mexico. From there, it runs northeast, intersecting with Interstate 165 (Alabama), ... [...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 own ...

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 broadcasting, radio was compelled to develop new and exclusive ways to programming by competition with Television broadcasting, 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 an ...
