Transmitter Heusweiler
The Heusweiler transmitter is a facility for medium wave broadcasting near Heusweiler, Germany, which originally went into service on 23 December 1935. On 19 June 1946 transmitter Heusweiler went in service again. Original transmitter It used a t-aerial, which was up-hung on two 35 and 31 meters tall wooden towers. The Heusweiler transmitter was destroyed on March 17, 1945 by war damage. First a t-aerial was used, which was, in the same year, replaced by a 50 metre tall steel framework mast insulated against ground, which exists still today and serves as reserve antenna. Replacement transmitters In 1948, a 120 meter high steel framework mast insulated from ground was built in Heusweiler. In the following years, the transmitting power of the Heusweiler transmitter was steadily increased. In 1965, another radio mast with a height of 120 meters was built, and in 1973 the transmitting power was increased to 1200 kilowatts, with the power reduced to 600 kilowatts at night. The He ...

Sender Heusweiler
A sender was a special type of circuit in 20th-century electromechanical telephone exchanges which registered the telephone numbers dialed by the subscriber, and then transmitted that information to another exchange. In some American exchange designs, for example, the No. 1 Crossbar switch there were both originating senders and terminating senders. The corresponding device in the British director telephone system was called a "director" and, in other contexts, "register". History The sender concept was developed to meet the needs of large city telephone switching systems, where the total number of subscriber lines and multiple central offices throughout the city required complex switching arrangements that were not easily handled by the direct control systems then in use, such as the step by step, or Strowger system. These limitations included inefficient trunking in large service areas, and a limited ability for growth and reorganization as additional subscribers were added. ...

T-aerial
A T-antenna, T-aerial, flat-top antenna, or (capacitively) top-loaded antenna is a monopole radio antenna with transverse capacitive loading wires attached to its top. T-antennas are typically used in the VLF, LF, MF, and shortwave bands, and are widely used as transmitting antennas for amateur radio stations, and long wave and medium wave AM broadcasting stations. They can also be used as receiving antennas for shortwave listening. The antenna consists of one or more horizontal wires suspended between two supporting radio masts or buildings and insulated from them at the ends. A vertical wire is connected to the center of the horizontal wires and hangs down close to the ground, connected to the transmitter or receiver. Combined, the two sections form a ‘T’ shape, hence the name. The transmitter power is applied, or the receiver is connected, between the bottom of the vertical wire and a ground connection. The T-antenna functions as a monopole antenna with capacitive to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antenna (radio)
In radio engineering, an antenna or aerial is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver. In transmission, a radio transmitter supplies an electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic wave In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, which propagate through space and carry momentum and electromagnetic radiant energy. It includes radio waves, microwaves, infrared, (visib ...s (radio waves). In Receiver (radio), reception, an antenna intercepts some of the power of a radio wave in order to produce an electric current at its terminals, that is applied to a receiver to be Amplifier, amplified. Antennas are essential components of all radio equipment. An antenna is an array of conductor (material), conductors (Driven element, elements), elect ...

Medium Wave
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ARD (broadcaster)
ARD is a joint organisation of Germany's regional public-service broadcasters. It was founded in 1950 in West Germany to represent the common interests of the new, decentralised, post-war broadcasting services – in particular the introduction of a joint television network. The ARD has a budget of €6.9 billion, 22,612 employees and is the largest public broadcaster network in the world. The budget comes primarily from a licence fee which every household, company and public institution are required by law to pay. For an ordinary household the fee is currently €18.36 per month. Households living on welfare are exempt from the fee. The fees are not collected directly by the ARD, but by the Beitragsservice (formerly known as Gebühreneinzugszentrale GEZ), a common organisation of the ARD member broadcasters, the second public TV broadcaster ZDF, and Deutschlandradio. ARD maintains and operates a national television network, called '' Das Erste'' ("The First") to differentiate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deutschlandfunk
Deutschlandfunk (DLF, ''Broadcast Germany'') is a public-broadcasting radio station in Germany, concentrating on news and current affairs. It is one of the four national radio channels produced by Deutschlandradio. History Broadcasting in the Federal Republic of Germany is reserved under the Basic Law (constitution) to the states. This means that all public broadcasting is regionalised. National broadcasts must be aired through the national consortium of regional public broadcasters ( ARD) or authorized by a treaty negotiated between the states. In the 1950s, the German Democratic Republic (GDR) began broadcasting its Deutschlandsender station on longwave. In response to this, the then-Nordwestdeutscher Rundfunk applied for a licence to operate a similar longwave service on behalf of the ARD. This was granted in 1956 and operated as Deutscher Langwellensender ("German Longwave Station"). On 29 November 1960, the federal government under Konrad Adenauer created ''Deutschlan ...

Bundesautobahn 8
is an autobahn in southern Germany that runs 497 km (309 mi) from the Luxembourg A13 motorway at Schengen via Neunkirchen, Pirmasens, Karlsruhe, Pforzheim, Stuttgart, Ulm, Augsburg and Munich to the Austrian West Autobahn near Salzburg. The A8 is a significant east–west transit route. Its construction began in March 1934 during Nazi rule as a ''Reichsautobahn'', the section between Karlsruhe and Salzburg having been completed by the time road works were discontinued in World War II. Although most parts have been modernized and extended since, significant sections remain in their original configuration from the 1930s - 2+2 lanes, no emergency lanes, steep hills and tight curves. In combination with today's traffic this makes the A8 one of the most crowded and dangerous autobahns in Germany. Especially in winter the slopes of the Black Forest, the Swabian Alb near Aichelberg, as well as the Irschenberg become bottlenecks when heavy trucks traverse the A8 uphill. ...

Saarländischer Rundfunk
Saarländischer Rundfunk (SR; ''Saarland Broadcasting'') is a public radio and television broadcaster serving the German state of Saarland. With headquarters in the Halberg Broadcasting House in Saarbrücken, SR is a member of the ARD consortium of German public-broadcasting organizations. History Broadcasting in the Saarland began in 1929, under the League of Nations mandate. In 1935, when the Saar rejoined Germany, Joseph Goebbels's Propagandaministerium established the ''Reichssender Saarbrücken'', under the control of the ''Reichs-Rundfunk GmbH Berlin''. After World War II, the Saarland was placed under French administration as the Saar Protectorate. The French military government established ''Radio Saarbrücken'' to serve the area. This became ''Saarländischer Rundfunk'' following the re-establishment of civilian government on 31 December 1947. In 1952, the Saarland introduced a law reorganizing radio broadcasting, and created ''Saarländischer Rundfunk GmbH'', a l ...

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 ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
