Cremlingen Transmitter
The Cremlingen transmitter is a large mediumwave transmission facility established in 1962 for transmitting the programme of Deutschlandfunk on 756 kHz near Cremlingen-Abbenrode. It was also known as ''Sender Braunschweig'' or ''Sender Königslutter''. The first transmitter was installed in 1962. It transmitted the program of Deutschlandfunk on 755 kHz (756 kHz from 1978 on) at a power of 100 kW and used as its aerial a 137-metre-high Guy-wire, guyed steel framework Radio masts and towers, mast. The transmitter power was raised to 200 kW one year later, but it only operated during daytime for some time. Interferences with the Ravensburg mediumwave transmitter which worked on the same frequency were common. A second transmitter was installed for the transmission of the Deutschlandfunk programme on 548 kHz from 28 October 1963, initially with a power of 200 kW. It used a 240-metre-high guyed steel tube mast as its aerial, which was insulated agains ...

Mediumwave
Medium wave (MW) is the part of the medium frequency (MF) radio band used mainly for AM radio broadcasting. The spectrum provides about 120 channels with more limited sound quality than FM stations on the FM broadcast band. During the daytime, reception is usually limited to more local stations, though this is dependent on the signal conditions and quality of radio receiver used. Improved signal propagation at night allows the reception of much longer distance signals (within a range of about 2,000 km or 1,200 miles). This can cause increased interference because on most channels multiple transmitters operate simultaneously worldwide. In addition, amplitude modulation (AM) is often more prone to interference by various electronic devices, especially power supplies and computers. Strong transmitters cover larger areas than on the FM broadcast band but require more energy and longer antennas. Digital modes are possible but have not reached momentum yet. MW was the main radio ban ...

Nordkirchen Transmitter
The Nordkirchen transmitter is a medium-wave broadcasting facility of Deutsche Telekom near Nordkirchen in Northrhine-Westphalia. It was built in 1979 and 1980 after the 549 kHz frequency was again made available in that location. It transmitted at a power of 100 kW and uses a directional antenna, aimed at the Northeast, consisting of two ground-fed, guyed, lattice steel masts 136 metres apart. The power opposite the antenna's focal point was approximately one-third the total radiated power. This avoided conflicting with the nearby Wavre Transmitter, Wavre transmitter in Belgium, which works on the neighbouring 540 kHz frequency. OFF AIR in 2007 In 2004, a second medium-wave transmitter with a power of 5 kW for transmitting the privately owned radio programme Truckradio was installed at Nordkirchen transmitter, which uses the same antenna as the transmitter of Deutschlandfunk.

1962 Establishments In West Germany
Year 196 ( CXCVI) was a leap year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Dexter and Messalla (or, less frequently, year 949 '' Ab urbe condita''). The denomination 196 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Radio Masts And Towers In Germany
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 a ...

Former Radio Masts And Towers
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the ad ...

Buildings And Structures In Lower Saxony
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ...

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 ...

Sender Freies Berlin
Sender Freies Berlin (; abbreviated SFB ; ) was the ARD public radio and television service for West Berlin from 1 June 1954 until 1990 and for Berlin as a whole from German reunification until 30 April 2003. On 1 May 2003 it merged with Ostdeutscher Rundfunk Brandenburg to form ''Rundfunk Berlin-Brandenburg''. History Pre-war In 1922, the ''Deutsche Stunde, Gesellschaft für drahtlose Belehrung und Unterhaltung mbH'' (German Society for Wireless Instruction and Entertainment Limited) was formed to promote the new science of radio broadcasting and reception. This institution began broadcasting on 29 October 1923 from Berlin. In 1933, German broadcasting was brought under Nazi state control and the station became ''Reichssender Berlin'', part of the national ''Großdeutscher Rundfunk'', controlled by Joseph Goebbels. The station was closed by the Allies at the end of the Battle of Berlin that brought the End of World War II in Europe. Post-war In the post-war four-power oc ...

Digital Radio Mondiale
Digital Radio Mondiale (DRM; ''mondiale'' being Italian and French for "worldwide") is a set of digital audio broadcasting technologies designed to work over the bands currently used for analogue radio broadcasting including AM broadcasting—particularly shortwave—and FM broadcasting. DRM is more spectrally efficient than AM and FM, allowing more stations, at higher quality, into a given amount of bandwidth, using xHE-AAC audio coding format. Various other MPEG-4 and Opus codecs are also compatible, but the standard now specifies xHE-AAC. Digital Radio Mondiale is also the name of the international non-profit consortium that has designed the platform and is now promoting its introduction. Radio France Internationale, TéléDiffusion de France, BBC World Service, Deutsche Welle, Voice of America, Telefunken (now Transradio) and Thomcast (now Ampegon) took part at the formation of the DRM consortium. The principle of DRM is that bandwidth is the limiting factor, and comp ...
