Berlin-Köpenick Transmitter
Berlin-Köpenick transmitter was a transmission facility for broadcasting on medium wave, short wave, and VHF in Berlin-Köpenick, Germany, near the suburb of Uhlenhorst, after which it was occasionally named. History Decisions of the construction of new medium wave transmitting facilities for the GDR were taken in 1950. One of them was originally planned at Nauen, but objections of the Soviet Military Administration in Germany led to the construction of ''Funkstelle Köpenick''. The first 250 kW transmitter produced by Funkwerk Köpenick was installed here, and the site served as the prototype for the following medium wave transmitter installations in the GDR. Construction started on 21 May 1951, transmissions on 6 July 1952. The building for the diesel generators was only completed in October 1953. In 1954 the site was renamed into ''Funkamt Berlin-Köpenick'' and put under the control of the Ministry for Post and Telecommunications. The second 250 kW transmitter w ...

Broadcasting
Broadcasting is the data distribution, distribution of sound, audio audiovisual content to dispersed audiences via a electronic medium (communication), mass communications medium, typically one using the electromagnetic spectrum (radio waves), in a :wikt:one-to-many, one-to-many model. Broadcasting began with AM radio, which came into popular use around 1920 with the spread of vacuum tube radio transmitters and radio receiver, receivers. Before this, most implementations of electronic communication (early radio, telephone, and telegraph) were wikt:one-to-one, one-to-one, with the message intended for a single recipient. The term ''broadcasting'' evolved from its use as the agricultural method of sowing seeds in a field by casting them broadly about. It was later adopted for describing the widespread distribution of information by printed materials or by telegraph. Examples applying it to "one-to-many" radio transmissions of an individual station to multiple listeners appeared as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adlershof
Adlershof (, literally "Eagle's Court") is a locality (') in the Boroughs of Berlin, borough (') Treptow-Köpenick of Berlin, Germany. Adlershof is home to the new City of Science, Technology and Media (WISTA), located on the southwestern edge of the locality. History A part of the area known today as the "City of Science, Technology and Media", was once known as the Johannisthal Air Field. Germany's first motorized aircraft took off from here at the beginning of the 20th century. Albatros Flugzeugwerke, Albatros, Fokker, Rumpler and Wright made Adlershof-Johannisthal famous. In 1912 the German Experimental Institute for Aviation (Deutsche Versuchsanstalt für Luftfahrt – DVL) made Adlershof its headquarters. Laboratories, motor test beds, wind tunnels and hangars were erected in the 20s and 30s and are historical landmarks today. World War I Adlershof is particularly well known for a series of competitions between various aviation firms' fighter aircraft designs that were held ...

Radio Masts And Towers In Germany
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 ...

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 used 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 cone 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 th ...

Buildings And Structures In Berlin
A building or edifice is an enclosed structure with a roof, walls and windows, usually standing permanently in one place, such as a house or factory. Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for numerous factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the concept, see ''Nonbuilding structure'' for contrast. Buildings serve several societal needs – occupancy, 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 separation of the human habitat (a place of comfort and safety) from the ''outside'' (a place that may be harsh and harmful at times). buildings have been objects or canvasses of much artistic expression. In recent years, interest in sustainable planning and building pract ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rundfunk Im Amerikanischen Sektor
RIAS (; ''Radio in the American Sector'') was a radio and television station in the American Sector of Berlin during the Cold War. It was founded by the US occupational authorities after World War II in 1946 to provide the German population in and around Berlin with news and political reporting.

Radio Jamming
Radio jamming is the deliberate blocking of or interference with wireless communications.https://apps.fcc.gov/edocs_public/attachmatch/DA-12-347A1.pdf Enforcement Advisory No. 2012-02 FCC Enforcement Advisory Cell Jammers, GPS Jammers, and Other Jamming Devices Consumer Alert: Using or Importing Jammers is Illegal In some cases, jammers work by the transmission of radio signals that disrupt telecommunications by decreasing the signal-to-noise ratio. The concept can be used in wireless data networks to disrupt information flow. It is a common form of censorship in totalitarian countries, in order to prevent foreign radio stations in border areas from reaching the country. Jamming is usually distinguished from interference that can occur due to device malfunctions or other accidental circumstances. Devices that simply cause interference are regulated differently. Unintentional "jamming" occurs when an operator transmits on a busy frequency without first checking whether it is in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Berlin International
