WNBS
WNBS (1340 AM) is a radio station broadcasting a News Talk Information format. Licensed to and serving Murray, Kentucky, United States, the station is currently owned by Forever Communications, Inc. and features programming from CBS News Radio, Fox Sports Radio, and Westwood One. History WNBS signed on in July 1948 under ownership by the newly-formed Murray Broadcasting Company. The station is named for Nathan B. Stubblefield, a Murray resident who was a pioneer in early experiments with wireless voice transmissions. In 1957, the station was purchased by C.H. Pulse and Chuck Shuffett of Lebanon. In the late 1950s or 1960s, the station was knocked off the air by an airplane that crashed into the transmission tower in heavy fog. In 1976, WNBS was sold to Timkay, Inc., but Shuffett reacquired the station in 1986. In 1991, Shuffett sold both WNBS and W46BE (UHF channel 46), to Keith Stubblefield.

Near And Far Field
The near field and far field are regions of the electromagnetic (EM) field around an object, such as a transmitting antenna, or the result of radiation scattering off an object. Non-radiative ''near-field'' behaviors dominate close to the antenna or scatterer, while electromagnetic radiation ''far-field'' behaviors predominate at greater distances. Far-field (electric) and (magnetic) radiation field strengths decrease as the distance from the source increases, resulting in an inverse-square law for the '' power'' intensity of electromagnetic radiation in the transmitted signal. By contrast, the near-fields and strengths decrease more rapidly with distance: The radiative field decreases by the inverse-distance squared, the reactive field by an inverse-''cube'' law, resulting in a diminished power in the parts of the electric field by an inverse fourth-power and sixth-power, respectively. The rapid drop in power contained in the near-field ensures that effects due to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Philo Farnsworth
Philo Taylor Farnsworth (August 19, 1906 – March 11, 1971), "The father of television", was the American inventor and pioneer who was granted the first patent for the television by the United States Government. Burns, R. W. (1998), ''Television: An international history of the formative years''. IET History of Technology Series, 22. LondonThe Institution of Engineering and Technology (IET) p. 370. . He also invented a video camera tube, and the image dissector. He commercially produced and sold a fully functioning television system, complete with receiver and camera—which he produced commercially through the Farnsworth Television and Radio Corporation from 1938 to 1951, in Fort Wayne, Indiana. In later life, Farnsworth invented a small nuclear fusion device, the Farnsworth Fusor, employing inertial electrostatic confinement (IEC). Like many fusion devices, it was not a practical device for generating nuclear power, although it provides a viable source of neutrons. The desi ...

Nikola Tesla
Nikola Tesla (;"Tesla" . ''Random House Webster's Unabridged Dictionary''. ; 10 July 1856 – 7 January 1943) was a Serbian-American engineer, futurist, and inventor. He is known for his contributions to the design of the modern alternating current (AC) electricity supply system. Born and raised in the Austrian Empire, Tesla first studied engineering and physics in the 1870s without receiving a degree. He then gained practical experience in the early 1880s working in telephony and at Continental Edison in the new electric power industry. In 1884 he immigrated to the United States, where he became a naturalized citizen. He worked for a short time at the Edison Machine Works in New York City before he struck out on his own. With the help of partners to finance and market his ideas, Tesla set up laboratories and companies in New York to ...
