WQYK-AM
WJBR (1010 kHz) is an AM radio station licensed to Seffner, Florida, United States, serving the Tampa Bay market with an all-podcast format known as "Podcast Radio US". Owned by the Beasley Broadcast Group, the station's studios are located on Executive Center Drive in St. Petersburg. By day, WJBR transmits with 50,000 watts, the maximum for commercial AM stations. As 1010 AM is a clear channel frequency reserved for Class A stations CFRB Toronto and CBR Calgary, WJBR must reduce power to 5,000 watts at night. Its transmitter is off Martin Luther King Jr. Boulevard (Florida State Road 574) in Seffner, using a directional antenna with three-tower array to protect other stations from interference. It is directional towards the east and west to protect WJXL Jacksonville by day, which also operates on 1010 AM.

Radio Broadcasting
Radio broadcasting is transmission of audio (sound), sometimes with related metadata, by radio waves to radio receivers belonging to a public audience. In terrestrial radio broadcasting the radio waves are broadcast by a land-based radio station, while in satellite radio the radio waves are broadcast by a satellite in Earth orbit. To receive the content the listener must have a broadcast radio receiver (''radio''). Stations are often affiliated with a radio network which provides content in a common radio format, either in broadcast syndication or simulcast or both. Radio stations broadcast with several different types of modulation: AM radio stations transmit in AM ( amplitude modulation), FM radio stations transmit in FM (frequency modulation), which are older analog audio standards, while newer digital radio stations transmit in several digital audio standards: DAB (digital audio broadcasting), HD radio, DRM ( Digital Radio Mondiale).

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] |
Florida State Road 574
State Road 574 (SR 574) is an east–west state highway in Central Hillsborough County, Florida. It runs from northwestern Tampa to Plant City, and parallels County Road 574 west of Mango. Route description Beginning at the intersection of U.S. Route 92 (US 92 or the Dale Mabry Highway) on the north side of Raymond James Stadium and the site of the former Tampa Stadium as Martin Luther King Jr. Boulevard (formerly Buffalo Avenue), SR 574 is a six-lane divided highway until it passes the home office of the Tampa Bay Buccaneers, and narrows down to a four-lane divided highway. Instantly, the road is surrounded by the Tampa Branch of St. Joseph's Hospital. The road remains a four-lane divided highway until it reaches Armenia Avenue and becomes a four-lane undivided highway with occasional left-turn lanes. The road crosses the Hillsborough River over a high bridge built in 1960. The intersection of southbound US 41 Business (US 41 Bus.) moves from Highland Avenue to Ta ...

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] |
