KYYS07
KYYS (1250 AM) is a commercial radio station broadcasting a Regional Mexican format. It is licensed to Kansas City, Kansas. While it is owned by Audacy, Inc., the operations are under a local marketing agreement (LMA) with Reyes Media Group. By day, KYYS is powered at 25,000 watts. But to protect other stations from interference on 1250 AM, it uses a directional antenna with a three-tower array at all times. Power is reduced to 3,700 watts at night. History In Lawrence and Topeka The station was first authorized, by telegram on April 27, 1927, as WREN, to the Jenny Wren flour company in Lawrence, Kansas. It operated at 1090 kHz for its first months and then used 1180 kHz, shared with KFKU, the radio station of the University of Kansas. On November 11, 1928, as part of the implementation of the Federal Radio Commission's General Order 40, WREN and KFRU were moved to 1220 kHz. In March 1941, under the provisions of the North American Regional Broadcastin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KZPT
KZPT (99.7 FM) is a hot adult contemporary radio station licensed to and serving the Kansas City metropolitan area. The station is owned by Audacy, Inc. Its transmitter is located in east Kansas City, and studios are located in Mission, Kansas. History Early years 99.7 FM's historic roots go back to an experimental station, W9XER, which began as an "Apex" high-frequency station owned by the Midland Broadcasting Company in Kansas City. In 1937, it was operating on 31.6 MHz, and by 1940 was transmitting on 42.46 MHz. In late 1941, W9XER was converted into one of the earliest FM stations, now transmitting on 46.5 MHz. In 1944 the station received a commercial license as KMBC-FM, and began daily broadcasts that June. In 1946, it moved to 97.9 FM. For two more years, KMBC-FM broadcast on 100.5 FM, until the station was deleted in December 1949. Metromedia later revived the KMBC-FM call letters, when the station signed on at its permanent 99.7 FM location on October ...

Radio Station
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. The encoding of a radio broadcast depends on whether it uses an analog or digital signal. Analog radio broadcasts use one of two types of radio wave modulation: amplitude modulation for AM radio, or frequency modulation for FM radio. Newer, digital radio stations transmit in several different digital audio standards, such as DAB (Digital Audio Broadcasting), HD radio, or DRM ( Digital Ra ...

North American Regional Broadcasting Agreement
The North American Regional Broadcasting Agreement (NARBA, ; ) refers to a series of international treaties that defined technical standards for AM band (mediumwave) radio stations. These agreements also addressed how frequency assignments were distributed among the signatories, with a special emphasis on high-powered clear-channel station, clear channel allocations. The initial NARBA bandplan, also known as the "Havana Treaty", was signed by the United States, Canada, Mexico, Cuba, the Dominican Republic, and Haiti on December 13, 1937, and took effect March 29, 1941. A series of modifications and adjustments followed, also under the NARBA name. NARBA's provisions were largely supplanted in 1983, with the adoption of the Regional Agreement for the Medium Frequency Broadcasting Service in Region 2 (Rio Agreement), which covered the entire Western hemisphere. However, current AM band assignments in North America largely reflect the standards first established by the NARBA agreement ...

General Order 40
The Federal Radio Commission's (FRC) General Order 40, dated August 30, 1928, described the standards for a sweeping reorganization of radio broadcasting in the United States. This order grouped the AM radio band transmitting frequencies into three main categories, which became known as Clear Channel, Regional, and Local. It also included provisions for coordination with Canadian station assignments. The majority of the reassignments resulting from the plan's implementation went into effect on November 11, 1928. Background Radio transmissions in the United States were originally regulated by the Department of Commerce, as authorized by the Radio Act of 1912. The first formal regulations governing broadcasts intended for the general public were adopted effective December 1, 1921. This initially established just two transmitting wavelengths: 360 meters (833 kHz) for "entertainment" broadcasts, and 485 meters (619 kHz) for "market news and weather reports".

Federal Radio Commission
The Federal Radio Commission (FRC) was a government agency that regulated United States radio communication from its creation in 1927 until 1934, when it was succeeded by the Federal Communications Commission (FCC). The FRC was established by the Radio Act of 1927, which replaced the Radio Act of 1912 after the earlier law was found to lack sufficient oversight provisions, especially for regulating broadcasting stations. In addition to increased regulatory powers, the FRC introduced the standard that, in order to receive a license, a radio station had to be shown to be "in the public interest, convenience, or necessity". Previous regulation Radio Act of 1912 Although radio communication (originally known as "wireless telegraphy") was developed in the late 1890s, it was largely unregulated in the United States until the passage of the Radio Act of 1912. This law set up procedures for the Department of Commerce to license radio transmitters, which initially consisted primaril ...

KFKU
KFKU was a Lawrence, Kansas AM radio station. It was licensed to the University of Kansas from its founding in 1924, until its suspension of operations in 1987 and deletion in 1996. History KFKU was first licensed on December 18, 1924, to the University of Kansas at Lawrence, for 500 watts on 1090 kHz. Its establishment was financed by a $20,000 grant from the engineering faculty. The station's debut broadcast on December 15 coincided with the "third annual radio night", and featured a concert by the KU band and a speech by Chancellor Ernest Lindley. Initial programming ran on Monday and Thursday nights and included lectures complementing correspondence courses in areas such as philosophy and Spanish, as well as special events such as commencement and basketball games. In mid-1927, KFKU was assigned to share its frequency with recently licensed WREN, also located in Lawrence, which had been set up to promote Jenny Wren flour. This had been proposed by R. C. Jackman, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lawrence, Kansas
Lawrence is a city in and the county seat of Douglas County, Kansas, United States, and the sixth-largest city in the state. It is in the northeastern sector of the state, astride Interstate 70 in Kansas, Interstate 70, between the Kansas River, Kansas and Wakarusa River, Wakarusa Rivers. As of the 2020 United States census, 2020 census, the population of the city was 94,934. The city is a college town with a significant student population, because it is home to both the University of Kansas (KU) and Haskell Indian Nations University (HINU).

WREN Advertisement (1935)
Wrens are a family, Troglodytidae, of small brown passerine birds. The family includes 96 species and is divided into 19 genera. All species are restricted to the New World except for the Eurasian wren that is widely distributed in the Old World. In Anglophone regions, the Eurasian wren is commonly known simply as the "wren", as it is the originator of the name. The name ''wren'' has been applied to other, unrelated birds, particularly the New Zealand wrens (Acanthisittidae) and the Australian wrens (Maluridae). Most wrens are visually inconspicuous though they have loud and often complex songs. Exceptions include the relatively large members of the genus ''Campylorhynchus'', which can be quite bold in their behaviour. Wrens have short wings that are barred in most species, and they often hold their tails upright. Wrens are primarily insectivorous, eating insects, spiders and other small invertebrates, but many species also eat vegetable matter and some eat small frogs and liza ...

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 * Junglins ...

Directional Antenna
A directional antenna or beam antenna is an antenna that radiates or receives greater radio wave power in specific directions. Directional antennas can radiate radio waves in beams, when greater concentration of radiation in a certain direction is desired, or in receiving antennas receive radio waves from one specific direction only. This can increase the power transmitted to receivers in that direction, or reduce interference from unwanted sources. This contrasts with omnidirectional antennas such as dipole antennas which radiate radio waves over a wide angle, or receive from a wide angle. The extent to which an antenna's angular distribution of radiated power, its radiation pattern, is concentrated in one direction is measured by a parameter called antenna gain. A high-gain antenna (HGA) is a directional antenna with a focused, narrow beam width, permitting more precise targeting of the radio signals. Most commonly referred to during space missions, these antennas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
