WRVA (AM)
WRVA (1140 kHz) is a commercial AM radio station licensed to Richmond and serving Central Virginia. WRVA airs a talk radio format and is owned by Audacy, Inc. Established in 1925, WRVA is one of Virginia's oldest radio stations, and the most powerful AM station in the Commonwealth. For much of its history, WRVA billed itself as the "Voice of Virginia." WRVA is a Class A, clear channel station, transmitting with 50,000 watts, the maximum for commercial AM stations in the U.S. It uses a directional antenna with a two-tower array to protect the other Class A station on 1140 AM, XEMR in Monterrey, Mexico. The transmitter is on WRVA Road near the James River in Henrico, Virginia. WRVA is also heard on 125 watt FM translator W241AP at 96.1 MHz in Midlothian, Virginia. Weekdays begin with "Richmond's Morning News with John Reid." Afternoon drive time is hosted by Jeff Katz. The rest of the weekday schedule comes from nationally syndicated shows including Glenn Beck, Dana L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

WRNL
WRNL (910 AM "910 AM The Fan") is a commercial radio station licensed to Richmond, Virginia. WRNL features a sports radio format and is owned and operated by Audacy, Inc. The studios, offices and transmitter are all co-located just north of the Richmond city line on Basie Road in Dumbarton, Virginia. By day, WRNL has a power of 5,000 watts non-directional. But to avoid interfering with other stations on 910 AM, at night it reduces power to 1,000 watts and uses a directional antenna. WRNL is licensed by the FCC to broadcast in the HD Radio (hybrid) format. The station also broadcasts on 250 watt FM translator W286DJ at 105.1 MHz.https://radio-locator.com/cgi-bin/finder?call=W286DJ&x=10&y=6&sr=Y&s=C Radio-Locoatr.com/W286DJ] It is also heard on the HD2 signal of sister station 94.5 WRVQ.

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.

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 ... [...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 Baham ... [...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.

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 was compelled to develop new and exclusive ways to programming by competition with 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 announcements between the tracks. Backgroun ...

Radio Station
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).

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 (frequency modulation) radio, Digital Audio Broadcasting (DAB), satellite radio, HD (digital) radio, Internet radio, music streaming se ...
