KC2XAK
KC2XAK was the world's first UHF television station, which went on the air on December 29, 1949. It was a broadcast translator of New York City's WNBT (today's WNBC), and broadcast on 529–535 MHz in Bridgeport, Connecticut. The station's launch was code-named "Operation Bridgeport", as a test by RCA and NBC, to determine if the UHF spectrum was feasible to use for communications and broadcasting as part of a nationwide television station plan. It was operational during a several-year freeze on new television stations by the FCC which lasted from October 1948 to April 1952. The station used a 1 kW transmitter with a 20-dB gain antenna on a tower elevated above average terrain at the top of Success Hill. This resulted in an effective radiated power of 10 kW. Operation Bridgeport was a success in the sense that it demonstrated the viability of UHF broadcasting, and UHF became a major part of the FCC's plan for new television licensing in the early 1950s.

List Of Experimental Television Stations
This page is a list of the experimental television stations before 1946. After 1945 (in the United States) the television frequencies were opened up to commercialization and regular broadcasts began. Regular broadcast television start dates vary widely by country; in many regions, initial broadcast video deployment was delayed due to mobilisation for World War II. (Note: The listing of current broadcast channels for these stations is not up-to-date as many Band I, low-VHF stations have moved to UHF frequencies as a result of digital television transition. This is less of an issue in the United Kingdom because of its all-UHF system, but most early US broadcasters were on affected channels before analogue shutdown. Very few full-service North American broadcasters remain on physical channels VHF 2-6 digitally due to Electromagnetic interference, impulse noise problems and strict limits on maximum transmitted power at these frequencies.)

KPTV
KPTV (channel 12) is a television station in Portland, Oregon, United States, affiliated with the Fox network. It is owned by Gray Media alongside Vancouver, Washington–licensed MyNetworkTV affiliate KPDX (channel 49). The two stations share studios on NW Greenbrier Parkway in Beaverton; KPTV's transmitter is located in the Sylvan-Highlands section of Portland. History Early years KPTV signed on the air on September 18, 1952, as Oregon's first television station. KPTV originally broadcast on channel 27, making it also the nation's first commercial television station to broadcast on the UHF band. (the first experimental UHF station was Bridgeport, Connecticut's KC2XAK on channel 24). The station was originally owned by Empire Coil. As Portland's only television station at the time, it carried programming from all four networks of the time: ABC, CBS, NBC and the DuMont Television Network.

Broadcast Relay Station
A broadcast relay station, also known as a satellite station, relay transmitter, broadcast translator (U.S.), re-broadcaster (Canada), repeater ( two-way radio) or complementary station (Mexico), is a broadcast transmitter which repeats (or transponds) the signal of a radio or television station to an area not covered by the originating station. These expand the broadcast range of a television or radio station beyond the primary signal's original coverage or improves service in the original coverage area. The stations may be (but are not usually) used to create a single-frequency network. They may also be used by an AM or FM radio station to establish a presence on the other band. Relay stations are most commonly established and operated by the same organisations responsible for the originating stations they repeat. Depending on technical and regulatory restrictions, relays may also be set up by unrelated organisations. Types Translators In its simplest form, a broadcast tra ...

Television Channels And Stations Disestablished In 1952
Television (TV) is a telecommunication medium for transmitting moving images and sound. Additionally, the term can refer to a physical television set rather than the medium of transmission. Television is a mass medium for advertising, entertainment, news, and sports. The medium is capable of more than "radio broadcasting", which refers to an audio signal sent to radio receivers. Television became available in crude experimental forms in the 1920s, but only after several years of further development was the new technology marketed to consumers. After World War II, an improved form of black-and-white television broadcasting became popular in the United Kingdom and the United States, and television sets became commonplace in homes, businesses, and institutions. During the 1950s, television was the primary medium for influencing public opinion.Diggs-Brown, Barbara (2011''Strategic Public Relations: Audience Focused Practice''p. 48 In the mid-1960s, color broadcasting was intro ...

History Of Bridgeport, Connecticut
The history of Bridgeport, Connecticut was, in the late 17th and most of the 18th century, one of land acquisitions from the native inhabitants, farming and fishing. From the mid-18th century to the mid-19th century, Bridgeport's history was one of shipbuilding, whaling and rapid growth. Bridgeport's growth accelerated even further from the mid-19th century to the mid-20th century with the advent of the railroad, Industrialization, massive immigration, labor movements until, at its peak population in 1950, Bridgeport with some 159,000 people was Connecticut's second most populous city. In the late 20th century, Bridgeport's history was one of deindustrialization and declining population, though it overtook Hartford, Connecticut, Hartford as the state's most populous city by 1980. Pre-colonial period Much of the land that became Bridgeport was originally occupied by the Pequonnock Indians of the Paugussett nation. One village consisted of about five or six hundred inhabitants in app ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Experimental Television Stations
An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale but always rely on repeatable procedure and logical analysis of the results. There also exist natural experimental studies. A child may carry out basic experiments to understand how things fall to the ground, while teams of scientists may take years of systematic investigation to advance their understanding of a phenomenon. Experiments and other types of hands-on activities are very important to student learning in the science classroom. Experiments can raise test scores and help a student become more engaged and interested in the material they are learning, especially when used over time. Experiments can vary from personal and informal natural comparisons ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Television In The United States
History is the systematic study of the past, focusing primarily on the human past. As an academic discipline, it analyses and interprets evidence to construct narratives about what happened and explain why it happened. Some theorists categorize history as a social science, while others see it as part of the humanities or consider it a hybrid discipline. Similar debates surround the purpose of history—for example, whether its main aim is theoretical, to uncover the truth, or practical, to learn lessons from the past. In a more general sense, the term ''history'' refers not to an academic field but to the past itself, times in the past, or to individual texts about the past. Historical research relies on primary and secondary sources to reconstruct past events and validate interpretations. Source criticism is used to evaluate these sources, assessing their authenticity, content, and reliability. Historians strive to integrate the perspectives of several sources to develop a ...

Mass Media In Bridgeport, Connecticut
Mass is an intrinsic property of a body. It was traditionally believed to be related to the quantity of matter in a body, until the discovery of the atom and particle physics. It was found that different atoms and different elementary particles, theoretically with the same amount of matter, have nonetheless different masses. Mass in modern physics has multiple definitions which are conceptually distinct, but physically equivalent. Mass can be experimentally defined as a measure of the body's inertia, meaning the resistance to acceleration (change of velocity) when a net force is applied. The object's mass also determines the strength of its gravitational attraction to other bodies. The SI base unit of mass is the kilogram (kg). In physics, mass is not the same as weight, even though mass is often determined by measuring the object's weight using a spring scale, rather than balance scale comparing it directly with known masses. An object on the Moon would weigh less than it d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
