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 signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, 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 modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Beloit College
Beloit College is a private liberal arts college in Beloit, Wisconsin. Founded in 1846, when Wisconsin was still a territory, it is the state's oldest continuously operated college. It is a member of the Associated Colleges of the Midwest and has an enrollment of roughly 1,400 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. The first building (then called Middle College) was built in 1847, and remains in operation. Classes began in the fall of 1847, with the first degrees awarded in 1851. Beloit's first president was a Yale University graduate, Aaron Lucius Chapin, who served from 1849 to 1886. The college became coeducatio ...

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 ar ...

Lee De Forest
Lee de Forest (August 26, 1873 – June 30, 1961) was an American inventor and a fundamentally important early pioneer in electronics. He invented the first electronic device for controlling current flow; the three-element " Audion" triode vacuum tube in 1906. This started the Electronic Age, and enabled the development of the electronic amplifier and oscillator. These made radio broadcasting and long distance telephone lines possible, and led to the development of talking motion pictures, among countless other applications. He had over 300 patents worldwide, but also a tumultuous career— he boasted that he made, then lost, four fortunes. He was also involved in several major patent lawsuits, spent a substantial part of his income on legal bills, and was even tried (and acquitted) for mail fraud. Despite this, he was recognised for his pioneering work with the 1922 IEEE Medal of Honor, the 1923 Franklin Institute Elliott Cresson Medal and the 1946 American Institute of ...

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. The population of the CDP was 4,970 at the 2010 census. History Brant Rock and Ocean Bluff were originally inhabited by Native Americans, including members of the Wampanoag tribe of the Algonquian peoples. Native American artifacts have been found extensively in the area. The main road through the area, known today as Ocean Street, is a Native American road, likely very ancient. The area at the end of Brant Rock village, known as Blackman's Point, was a Native American campground. In the 1630s, the government of the Pilgrim settlers at Plymouth began to give out land grants in the area. The Ocean Bluff area was first granted to the governor of the Pilgrims. It was known by about 1638 as "Governor's Island.” Later on in the 17th century, it became known as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reginald Fessenden
Reginald Aubrey Fessenden (October 6, 1866 – July 22, 1932) was a Canadian-born inventor, who did a majority of his work in the United States and also claimed U.S. citizenship through his American-born father. During his life he received hundreds of patents in various fields, most notably ones related to radio and sonar. Fessenden is best known for his pioneering work developing 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 a lack of verifiable details has led to some doubts about this claim. Early years Reginald Fessenden was born October 6, 1866, in East Bolton, Quebec, the eldest of the Reverend Elisha Joseph Fessenden and Clementina Trenholme's four children. Elisha ...

Devonport, Tasmania
Devonport ( ; Palawa Kani: ''Tiagarra'') is a city in northern Tasmania, Australia, located on the lands of the Pannilerpanner clan of the Palawa nation. It is situated at the mouth of the Mersey River. Devonport had an urban population of 26,150 at the 2021 Australian census. History The first European settlement before 1850 was on a block of land at Frogmore, near present-day Latrobe. In 1850, a settler named Oldaker occupied land at present-day Devonport. Saw milling and coal mining developed with settlers arriving from England in 1854 on board the sailing ship 'Balmoral'. During the 1850s the twin settlements of Formby and Torquay were established on opposite banks at the mouth of the Mersey River. Torquay on the eastern shore was the larger community with police, post, magistrate, at least three hotels, shipyards and stores. A river ferry service connected the two communities. Between 1870 and 1880 the shipping industry grew and work was undertaken to deepen the mouth of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 Austra ...

Signal Hill, St
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 signal. 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, with cell signaling. Signaling theory, in evolutionary biology, proposes that a substantial driver for evolution is the ability of animals to communicate with each other by developing ways of signaling. In human engineering, signals are typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
