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". The number of ...

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 primarily ...

WHO (AM)
WHO (1040 kHz "Newsradio 1040") is a commercial AM radio station in Des Moines, Iowa, United States. The station is owned by iHeartMedia and carries a news/talk radio format. The radio studios are on Grand Avenue in Des Moines. WHO broadcasts with 50,000 watts, the maximum power permitted for commercial AM stations.

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] |
Eastern Standard Time (North America)
The Eastern Time Zone (ET) is a time zone encompassing part or all of 23 states in the eastern part of the United States, parts of eastern Canada, the state of Quintana Roo in Mexico, Panama, Colombia, mainland Ecuador, Peru, and a small portion of westernmost Brazil in South America, along with certain Caribbean and Atlantic islands. Places that use: * Eastern Standard Time (EST), when observing standard time (autumn/winter), are five hours behind Coordinated Universal Time ( UTC−05:00). * Eastern Daylight Time (EDT), when observing daylight saving time (spring/summer), are four hours behind Coordinated Universal Time ( UTC−04:00). On the second Sunday in March, at 2:00 a.m. EST, clocks are advanced to 3:00 a.m. EDT leaving a one-hour "gap". On the first Sunday in November, at 2:00 a.m. EDT, clocks are moved back to 1:00 a.m. EST, thus "duplicating" one hour. Southern parts of the zone (Panama and the Caribbean) do not observe daylight saving time. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North American Regional Broadcasting Agreement
The North American Regional Broadcasting Agreement (NARBA, es, Convenio Regional Norteamericano de Radiodifusión) 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 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 es ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
