Oldest Radio Station
It is generally recognised that the first radio transmission was made from a temporary station set up by Guglielmo Marconi in 1895. This followed on from pioneering work in the field by a number of people including Alessandro Volta, André-Marie Ampère, Georg Ohm and James Clerk Maxwell.Mimi Colligan, ''Golden Days of Radio'', Australia Post, 1991 The several potential contenders for the title of "oldest radio station" are listed below, organized by sign-on date. These are not restricted to radio broadcasting, i.e., the transmissions were not necessarily intended to reach a wide audience.

Radio Transmission
Radio is the technology of telecommunication, communicating using radio waves. Radio waves are electromagnetic waves of frequency between 3 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna (radio), antenna which radiates the waves. They can be received by other antennas connected to a radio receiver; this is the fundamental principle of radio communication. In addition to communication, radio is used for radar, radio navigation, radio control, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by Modulation, modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the tran ...

Beloit College
Beloit College is a private liberal arts college in Beloit, Wisconsin, United States. Founded in 1846 when Wisconsin was still a territory, it is the state's oldest continuously operated college. It has an enrollment of roughly 1,000 undergraduate students. History Beloit College was founded by the group Friends for Education, which was started by seven pioneers from New England who, soon after their arrival in the Wisconsin Territory, agreed that a college needed to be established. The group raised funds for a college in their town and convinced the territorial legislature to enact the charter for Beloit College on February 2, 1846.

Parker Building (New York City)
The Parker Building was a 12-story office and loft structure completed in 1900 at the southeast corner of Fourth Avenue (later Park Avenue South) and 19th Street, in Manhattan, New York City. The edifice occupied ground which was formerly the site of the Gettysburg Cyclorama structure. Insurance company property In 1902 the Parker Building was acquired by the Metropolitan Life Insurance Company. The acquisition was brokered by Frank E. Smith through John F. Hollingsworth. The latter accepted the Westminster Hotel, at Irving Place, as partial payment. The aggregate mortgage on the Parker Building at the time was $900,000. Temporary art gallery Government experts appraised paintings and statuary from the Don Marcello Massaranti collection of Italian art on the 10th floor of the Parker Building in July 1902. As of August 1904 the art collection continued to be exhibited there. Henry Walters bought the collection for $1,000,000 in Rome, Italy, in 1902. He eventually moved the art ...

Brant Rock
Ocean Bluff-Brant Rock is a census-designated place (CDP) in Plymouth County, Massachusetts, United States, composed of the neighborhoods of Ocean Bluff, Brant Rock, Fieldston, and Rexhame in the town of Marshfield.

Reginald Fessenden
Reginald Aubrey Fessenden (October 6, 1866 – July 22, 1932) was a Canadian-American electrical engineer and inventor who received hundreds of List of Reginald Fessenden patents, patents in fields related to radio and sonar between 1891 and 1936 (seven of them after his death). Fessenden pioneered developments in radio technology, including the foundations of amplitude modulation (AM) radio. His achievements included the first transmission of speech by radio (1900), and the first two-way radiotelegraphic communication across the Atlantic Ocean (1906). In 1932 he reported that, in late 1906, he also made the first radio broadcast of entertainment and music, although that claim has not been well documented.

History Of Broadcasting In Australia
The history of broadcasting in Australia has been shaped for over a century by the problem of communication across long distances, coupled with a strong base in a wealthy society with a deep taste for aural communications in a silent landscape. Australia developed its own system, through its own engineers, manufacturers, retailers, newspapers, entertainment services, and news agencies. The government set up the first radio system, and business interests marginalized the hobbyists and amateurs. The Labor Party was especially interested in radio because it allowed them to bypass the newspapers, which were mostly controlled by the opposition. Both parties agreed on the need for a national system, and in 1932 set up the Australian Broadcasting Commission, as a government agency that was largely separate from political interference. The first commercial broadcasters, originally known as "B" class stations were on the air as early as 1925. Many were sponsored by newspapers in Austr ...

Signal Hill, St
A signal is both the process and the result of transmission of data over some media accomplished by embedding some variation. Signals are important in multiple subject fields including signal processing, information theory and biology. In signal processing, a signal is a function that conveys information about a phenomenon. Any quantity that can vary over space or time can be used as a signal to share messages between observers. The '' IEEE Transactions on Signal Processing'' includes audio, video, speech, image, sonar, and radar as examples of signals. A signal may also be defined as observable change in a quantity over space or time (a time series), even if it does not carry information. In nature, signals can be actions done by an organism to alert other organisms, ranging from the release of plant chemicals to warn nearby plants of a predator, to sounds or motions made by animals to alert other animals of food. Signaling occurs in all organisms even at cellular levels, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
