Ernst Alexanderson
Ernst Frederick Werner Alexanderson (January 25, 1878 – May 14, 1975) was a Swedish-American electrical engineer, who was a pioneer in radio and television development. He invented the Alexanderson alternator, an early radio transmitter used between 1906 and the 1930s for longwave long distance radio transmission. Alexanderson also created the amplidyne, a direct current amplifier used during the Second World War for controlling anti-aircraft guns. Background Alexanderson was born in Uppsala, Sweden. He studied at the University of Lund (1896–97) and was educated at the Royal Institute of Technology in Stockholm and the Technische Hochschule in Berlin, Germany. He emigrated to the United States in 1902 and spent much of his life working for the General Electric and Radio Corporation of America. Engineering work Alexanderson designed the Alexanderson alternator, an early longwave radio transmitter, one of the first devices which could transmit modulated audio (sound) over rad ...

Tuned Radio Frequency Receiver
A tuned radio frequency receiver (or TRF receiver) is a type of radio receiver that is composed of one or more tuned radio frequency (RF) amplifier stages followed by a detector (demodulator) circuit to extract the audio signal and usually an audio frequency amplifier. This type of receiver was popular in the 1920s. Early examples could be tedious to operate because when tuning in a station each stage had to be individually adjusted to the station's frequency, but later models had ganged tuning, the tuning mechanisms of all stages being linked together, and operated by just one control knob. By the mid 1930s, it was replaced by the superheterodyne receiver patented by Edwin Armstrong. Background The TRF receiver was patented in 1916 by Ernst Alexanderson. His concept was that each stage would amplify the desired signal while reducing the interfering ones. Multiple stages of RF amplification would make the radio more sensitive to weak stations, and the multiple tuned circuit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio 2XG
Radio station 2XG, also known as the "Highbridge Station", was an experimental radio station located in New York City and licensed to the De Forest Radio Telephone and Telegraph Company from 1915–1917 and 1920–1924. In 1916, it became the first radio station employing a vacuum-tube transmitter to make news and entertainment broadcasts on a regular schedule, and, on November 7, 1916, became the first to broadcast U.S. presidential election returns by spoken word instead of by Morse code. Pre-World War I history Initially all radio stations used spark transmitters, which could only transmit Morse code messages. In 1904, Valdemar Poulsen invented an "arc-transmitter" capable of transmitting full audio, and in late 1906 Lee de Forest founded the Radio Telephone Company and began producing his own "sparkless" arc-transmitters. Between 1907 and 1910, de Forest made a number of demonstration entertainment broadcasts, and even spoke about developing news and entertainment broadcasting ...

WHA (AM)
WHA (970 AM) is a non-commercial radio station, licensed since 1922 to the University of Wisconsin and located in Madison, Wisconsin. It serves as the flagship for the Wisconsin Public Radio talk-based "Ideas Network". WHA's programming is also broadcast by two low-powered FM translators, and by WERN FM's HD3 digital subchannel. The station airs a schedule of news and talk programs from Wisconsin Public Radio, NPR, American Public Media, Public Radio International, the Canadian Broadcasting Corporation and the BBC. The same call letters are used by WHA-TV in Madison, the flagship station for PBS Wisconsin. Broadcast frequencies WHA transmits on 970 AM from a 258-foot tower at Silver Spring Farm within the University of Wisconsin–Madison Arboretum. It operates at 5,000 watts during the day. Although WHA's tower is relatively short by modern broadcasting standards, its transmitter power and Wisconsin's flat land (with near-perfect ground conductivity) gives it a daytime cove ...

Virginia Gregg
Virginia, officially the Commonwealth of Virginia, is a state in the Mid-Atlantic and Southeastern regions of the United States, between the Atlantic Coast and the Appalachian Mountains. The geography and climate of the Commonwealth are shaped by the Blue Ridge Mountains and the Chesapeake Bay, which provide habitat for much of its flora and fauna. The capital of the Commonwealth is Richmond; Virginia Beach is the most-populous city, and Fairfax County is the most-populous political subdivision. The Commonwealth's population was over 8.65million, with 36% of them living in the Baltimore–Washington metropolitan area. The area's history begins with several indigenous groups, including the Powhatan. In 1607, the London Company established the Colony of Virginia as the first permanent English colony in the New World. Virginia's state nickname, the Old Dominion, is a reference to this status. Slave labor and land acquired from displaced native tribes fueled the growing p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Iva Toguri D'Aquino
Iva Ikuko Toguri D'Aquino ( ja, 戸栗郁子 アイバ; July 4, 1916 – September 26, 2006) was a Japanese-American disc jockey and radio personality who participated in English-language radio broadcasts transmitted by Radio Tokyo to Allied troops in the South Pacific during World War II on ''The Zero Hour'' radio show. Toguri called herself " Orphan Ann", but she quickly became inaccurately identified with the name "Tokyo Rose", coined by Allied soldiers and which predated her broadcasts. After the surrender of Japan, Toguri was detained for a year by the United States military before being released for lack of evidence. US Department of Justice officials agreed that her broadcasts were " innocuous", but when Toguri tried to return to the US a popular uproar ensued, prompting the Federal Bureau of Investigation to renew its investigation of Toguri's wartime activities. She was subsequently charged by the US Attorney's Office with eight counts of treason. Her 1949 trial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
