Sender Zehlendorf
Sender Zehlendorf or Zehlendorf (radio) transmission facility was a radio transmission facility which was in service since 1936, when a short wave transmitter was built on the occasion of the Berlin 1936 Summer Olympics in Zehlendorf (a village near Oranienburg) as part of the establishment of permanent radio services. This Zehlendorf site, which until the end of World War II was referred to as the Rehmate Radio Transmission Centre (german: Funksendestelle Rehmate), had 26 different antennas at the time (that is, before and at the end of World War II). In 2017 the last antenna at the site was demolished by controlled implosion, ending the era of the transmission towers in Zehlendorf. History In 1945, most of the Rehmate Radio Transmission Centre was dismantled by the Soviet occupying forces as reparation, who left only three wooden radio masts. Two of these wooden masts supplied the building material for a 100-metre-tall transmission tower built at Golm in 1948, which was us ...

Effective Radiated Power
Effective radiated power (ERP), synonymous with equivalent radiated power, is an IEEE standardized definition of directional radio frequency (RF) power, such as that emitted by a radio transmitter. It is the total power in watts that would have to be radiated by a half-wave dipole antenna to give the same radiation intensity (signal strength or power flux density in watts per square meter) as the actual source antenna at a distant receiver located in the direction of the antenna's strongest beam (main lobe). ERP measures the combination of the power emitted by the transmitter and the ability of the antenna to direct that power in a given direction. It is equal to the input power to the antenna multiplied by the gain of the antenna. It is used in electronics and telecommunications, particularly in broadcasting to quantify the apparent power of a broadcasting station experienced by listeners in its reception area. An alternate parameter that measures the same thing is effec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Simulcast
Simulcast (a portmanteau of simultaneous broadcast) is the broadcasting of programmes/programs or events across more than one resolution, bitrate or medium, or more than one service on the same medium, at exactly the same time (that is, simultaneously). For example, Absolute Radio is simulcast on both AM and on satellite radio. Likewise, the BBC's Prom concerts were formerly simulcast on both BBC Radio 3 and BBC Television. Another application is the transmission of the original-language soundtrack of movies or TV series over local or Internet radio, with the television broadcast having been dubbed into a local language. Early radio simulcasts Before launching stereo radio, experiments were conducted by transmitting left and right channels on different radio channels. The earliest record found was a broadcast by the BBC in 1926 of a Halle Orchestra concert from Manchester, using the wavelengths of the regional stations and Daventry. In its earliest days the BBC often transmit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voice Of Russia
Voice of Russia ( rus, Голос России, r=Golos Rossii), commonly abbreviated VOR, was the Russian government's international radio broadcasting service from 1993 until 2014, when it was reorganised as Radio Sputnik. Its interval signal was a chime version of 'Majestic' chorus from the ''Great Gate of Kiev'' portion of ''Pictures at an Exhibition'' by Mussorgsky. History Russian President Boris Yeltsin issued a decree on 22 December 1993 which reorganised Radio Moscow under a new name: Voice of Russia. On 9 December 2013, Russian President Vladimir Putin issued a presidential decree dissolving the Voice of Russia as an agency, and merging it with RIA Novosti to form the ''Rossiya Segodnya'' international news agency. Margarita Simonyan, editor-in-chief of the Rossiya Segodnya, said in March 2014 that "We will stop using obsolete radio broadcasting models, when the signal is transmitted without any control and when it is impossible to calculate who listens to it and wher ...

Transmitter Berlin-Koepenick
In electronics and telecommunications, a radio transmitter or just transmitter is an electronic device which produces radio waves with an antenna. The transmitter itself generates a radio frequency alternating current, which is applied to the antenna. When excited by this alternating current, the antenna radiates radio waves. Transmitters are necessary component parts of all electronic devices that communicate by radio, such as radio and television broadcasting stations, cell phones, walkie-talkies, wireless computer networks, Bluetooth enabled devices, garage door openers, two-way radios in aircraft, ships, spacecraft, radar sets and navigational beacons. The term ''transmitter'' is usually limited to equipment that generates radio waves for communication purposes; or radiolocation, such as radar and navigational transmitters. Generators of radio waves for heating or industrial purposes, such as microwave ovens or diathermy equipment, are not usually called transmitters, even ...
