List Of Three-letter Broadcast Call Signs In The United States
This is a list of radio and television broadcasting stations in the United States that are currently assigned three-letter call signs. Overview In the United States, all radio and television broadcasting stations that are licensed by the Federal Communications Commission (FCC) are assigned official, and unique, call signs. Organized broadcasting began in the U.S. in the early 1920s on the AM band — FM and television did not exist yet. Initially most broadcasting stations were assigned three-letter calls; however, a switch was made in April 1922 to primarily four-letter calls, after the number of stations had increased into the hundreds. For a few years thereafter a small number of new three-letter calls continued to be issued. Although most of the original three-letter calls were randomly assigned, these later calls were often specially requested to match station slogans. The last new three-letter call was assigned to station WIS (now WVOC) in Columbia, South Carolina on Janua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kilohertz
The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), equivalent to one event (or cycle) per second. The hertz is an SI derived unit whose expression in terms of SI base units is s−1, meaning that one hertz is the reciprocal of one second. It is named after Heinrich Rudolf Hertz (1857–1894), the first person to provide conclusive proof of the existence of electromagnetic waves. Hertz are commonly expressed in multiples: kilohertz (kHz), megahertz (MHz), gigahertz (GHz), terahertz (THz). Some of the unit's most common uses are in the description of periodic waveforms and musical tones, particularly those used in radio- and audio-related applications. It is also used to describe the clock speeds at which computers and other electronics are driven. The units are sometimes also used as a representation of the energy of a photon, via the Planck relation ''E'' = ''hν'', where ''E'' is the photon's energy, ''ν'' is its frequ ...

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 o ...
