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 transmissions, but also on the longwave and shortwave radio bands.
Radio broadcasting is the broadcasting 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 that 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, FM radio stations transmit in FM, which are older analog audio standards, while newer digital radio stations transmit in several digital audio standards: DAB, HD radio, DRM. Television broadcasting is a separate service that also uses radio frequencies to broadcast television (video) signals.
A pirate radio station is a radio station that broadcasts without a valid license.
In-band on-channel (IBOC) is a hybrid method of transmitting digital radio and analog radio broadcast signals simultaneously on the same frequency. The name refers to the new digital signals being broadcast in the same AM or FM band (in-band), and associated with an existing radio channel (on-channel). By utilizing additional digital subcarriers or sidebands, digital information is "multiplexed" on existing signals, thus avoiding re-allocation of the broadcast bands.
Low-power broadcasting is broadcasting by a broadcast station at a low transmitter power output to a smaller service area than "full power" stations within the same region. It is often distinguished from "micropower broadcasting" and broadcast translators. LPAM, LPFM and LPTV are in various levels of use across the world, varying widely based on the laws and their enforcement.
A non-commercial educational station is a radio station or television station that does not accept on-air advertisements, as defined in the United States by the Federal Communications Commission (FCC) and was originally intended to offer educational programming as part, or whole, of its programming. NCE stations do not pay broadcast license fees for their non-profit uses of the radio spectrum. Stations which are almost always operated as NCE include public broadcasting, community radio, and college radio, as well as many religious broadcasting stations. Nearly all Non-Commercial radio stations derive their support from listener support, grants and endowments, such as the governmental entity Corporation for Public Broadcasting (CPB) that distributes supporting funds provided by the congress to support Public Radio.
Digital radio is the use of digital technology to transmit or receive across the radio spectrum. Digital transmission by radio waves includes digital broadcasting, and especially digital audio radio services.
In U.S., 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.
Radio Newyork International was the name of a pirate radio station which broadcast from a ship anchored in international waters off Jones Beach, New York, United States in 1987 and 1988. The history of Radio Newyork International (RNI) is linked with the Falling Star Network and other New York City area pirate radio stations. The owner of RNI, Allan Weiner, is currently the licensee of WBCQ shortwave in Monticello, Maine.
XERA is a radio station in Mexico, broadcasting on 760 AM in San Cristóbal de las Casas, Chiapas. The callsign was most famous for its use on a border blaster at Villa Acuña, Coahuila.
A broadcast license is a type of spectrum license granting the licensee permission to use a portion of the radio frequency spectrum in a given geographical area for broadcasting purposes. The licenses generally include restrictions, which vary from band to band.
Apex radio stations was the name commonly given to a short-lived group of United States broadcasting stations, which were used to evaluate transmitting on frequencies that were much higher than the ones used by standard amplitude modulation (AM) and shortwave stations. Their name came from the tall height of their transmitter antennas, which were needed because coverage was primarily limited to local line-of-sight distances. These stations were assigned to what at the time were described as "ultra-high shortwave" frequencies, between roughly 25 and 44 MHz. They employed amplitude modulation (AM) transmissions, although in most cases using a wider bandwidth than standard broadcast band AM stations, in order to provide high fidelity sound with less static and distortion.
WKSB is a commercial radio station licensed to serve Williamsport, Pennsylvania. The station is owned by iHeartMedia, Inc., through licensee iHM Licenses, LLC, and broadcasts an adult contemporary format, switching to Christmas music for much of November and December. Its broadcast tower is located on Bald Eagle Mountain south of Williamsport at.
KKLF is a commercial radio station licensed to Richardson, Texas. Although the station's signal covers portions of the Dallas-Fort Worth Metroplex, it mainly serves areas of North Texas that are north and east of the Metroplex. This station broadcasts on the AM expanded band. It is owned by Claro Communications, Ltd., with Gerald Benavides as the licensee. It broadcasts a Tejano radio format, using the monikers "Jalapeño Radio". The DJs speak both Spanish and English.
A broadcast relay station, also known as a satellite station, relay transmitter, broadcast translator (U.S.), re-broadcaster (Canada), repeater or complementary station (Mexico), is a broadcast transmitter which repeats the signal of a radio or television station to an area not covered by the originating station.
A border blaster is a broadcast station that, though not licensed as an external service, is, in practice, used to target another country. The term "border blaster" is of North American origin, and usually associated with Mexican AM stations whose broadcast areas cover large parts of the United States, and United States border AM stations covering large parts of Canada. Conceptually similar European broadcasting included some pre-World War II broadcasting towards the United Kingdom, "radio périphérique" around France and the U.S. government-funded station Radio Free Europe, targeting eastern Europe.
Call signs in Mexico are unique identifiers for telecommunications, radio communication, radio broadcasting and transmission. They are regulated internationally by the International Telecommunication Union (ITU) as well as nationally by the Federal Telecommunications Institute, which regulates broadcast stations, wireless telecommunications and spectrum use.
KMAE was an American commercial radio station licensed in 2010 to serve the community of Bruni, Texas. The station's broadcast license was held by accordion player and Christian evangelist Paulino D. Bernal Sr. of McAllen, Texas.
Radio in Mexico is a mass medium with 98 percent national penetration and a wider diversity of owners and programming than on television. In a model similar to that of radio in the United States, Mexican radio in its history has been largely commercial, but with a strong state presence and a rising number of noncommercial stations in the 2000s and early 2010s. In August 2015, there were 1,999 legal radio stations, almost 75 percent of them on the FM band.
