The Progressive Farmer
''Progressive Farmer'' is an agricultural magazine, published 14 times a year by Data Transmission Network, DTN. The magazine is based in Birmingham, Alabama, Birmingham, Alabama. History Founded in Winston, North Carolina, in 1886 by North Carolina native Leonidas Lafayette Polk (1837–1892; a Confederate Army veteran who is often confused with CSA General Leonidas Polk, no relation), the publication was intended to bring the latest information on crop and livestock production to the reunited nation's agrarian economy in the Southeastern United States, Southeast. After Polk died in 1892, Clarence Hamilton Poe, Clarence H. Poe from Raleigh, NC, took over as editor in 1899, and in 1903, he and three partners purchased the publication, taking it from a newspaper to a magazine with 36,000 subscribers by 1908.

The Des Moines Register
''The Des Moines Register'' is the daily morning newspaper of Des Moines, Iowa. History Early period The first newspaper in Des Moines was the ''Iowa Star''. In July 1849, Barlow Granger began the paper in an abandoned log cabin by the junction of the Des Moines and Raccoon River. In 1854, ''The Star'' became the ''Iowa Statesman'' which was also a Democratic paper. In 1857, ''The Statesman'' became the ''Iowa State Journal'', which published 3 times per week. In 1870, ''The Iowa Statesman'' became the ''Iowa State Leader'' as a Democratic newspaper, which competed with pro-Republican ''Iowa Daily State Register'' for the next 32 years.

WILL-TV
WILL-TV (channel 12) is a PBS member television station licensed to Urbana, Illinois, United States, serving the Central Illinois region. Owned by the University of Illinois Urbana-Champaign as part of Illinois Public Media, it is sister to NPR member stations WILL (580 AM) and WILL-FM (90.9). The three stations share studios at Campbell Hall for Public Telecommunication on the university's campus; WILL-TV's transmitter is located on East 1700th Road North, west of Monticello. History Commercial television operation in the United States was first authorized in 1941. However, by 1948, the Federal Communications Commission (FCC) determined that insufficient channels had been created to provide for national interference-free coverage, and there was also a need to set aside allocations for use by non-commercial educational stations. In order to give itself time to review options, a "freeze" on new TV station construction was announced, which would last until 1952. Meanwhile, in May ...

Public Broadcasting
Public broadcasting involves radio, television and other electronic media outlets whose primary mission is public service. Public broadcasters receive funding from diverse sources including license fees, individual contributions, public financing and commercial financing. Public broadcasting may be nationally or locally operated, depending on the country and the station. In some countries a single organization runs public broadcasting. Other countries have multiple public-broadcasting organizations operating regionally or in different languages. Historically, public broadcasting was once the dominant or only form of broadcasting in many countries (with the notable exceptions of the United States, Mexico and Brazil). Commercial broadcasting now also exists in most of these countries; the number of countries with only public broadcasting declined substantially during the latter part of the 20th century. Definition The primary mission of public broadcasting is that of public servic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sideband
In radio communications, a sideband is a band of frequencies higher than or lower than the carrier frequency, that are the result of the modulation process. The sidebands carry the information transmitted by the radio signal. The sidebands comprise all the spectral components of the modulated signal except the carrier. The signal components above the carrier frequency constitute the upper sideband (USB), and those below the carrier frequency constitute the lower sideband (LSB). All forms of modulation produce sidebands. Sideband creation We can illustrate the creation of sidebands with one trigonometric identity: :\cos(A)\cdot \cos(B) \equiv \tfrac\cos(A+B) + \tfrac\cos(A-B) Adding \cos(A) to both sides: :\cos(A)\cdot +\cos(B)= \tfrac\cos(A+B) + \cos(A) + \tfrac\cos(A-B) Substituting (for instance) A \triangleq 1000\cdot t and B \triangleq 100\cdot t, where t represents time: :\underbrace_\cdot \underbrace_ = \underbrace_ + \underbrace_ + \unde ...

FM Radio
FM broadcasting is a method of radio broadcasting using frequency modulation (FM). Invented in 1933 by American engineer Edwin Armstrong, wide-band FM is used worldwide to provide high fidelity sound over broadcast radio. FM broadcasting is capable of higher fidelity—that is, more accurate reproduction of the original program sound—than other broadcasting technologies, such as AM broadcasting. It is also less susceptible to common forms of interference, reducing static and popping sounds often heard on AM. Therefore, FM is used for most broadcasts of music or general audio (in the audio spectrum). FM radio stations use the very high frequency range of radio frequencies. Broadcast bands Throughout the world, the FM broadcast band falls within the VHF part of the radio spectrum. Usually 87.5 to 108.0 MHz is used, or some portion thereof, with few exceptions: * In the former Soviet republics, and some former Eastern Bloc countries, the older 65.8–74 MHz band ...

Grain Elevator
A grain elevator is a facility designed to stockpile or store grain. In the grain trade, the term "grain elevator" also describes a tower containing a bucket elevator or a pneumatic conveyor, which scoops up grain from a lower level and deposits it in a silo or other storage facility. In most cases, the term "grain elevator" also describes the entire elevator complex, including receiving and testing offices, weighbridges, and storage facilities. It may also mean organizations that operate or control several individual elevators, in different locations. In Australia, the term describes only the lifting mechanism. Before the advent of the grain elevator, grain was usually handled in bags rather than in bulk (large quantities of loose grain). Dart's Elevator was a major innovation. It was invented by Joseph Dart, a merchant, and Robert Dunbar, an engineer, in 1842 and 1843, in Buffalo, New York. Using the steam-powered flour mills of Oliver Evans as their model, they invented th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
