Mainflingen longwave transmitter is a large facility for commercial longwave transmissions at Mainflingen, Hesse, Germany, which was built in 1956. It uses several T- and triangle antennas, which are mounted on guyed masts of lattice steel, insulated against ground. The used masts have heights between 150 metres and 200 metres.
Southeast of the main antenna area, which is completely fenced in, but still north of the motorway A3 there is a further T-antenna, which is mounted on two guyed masts of lattice steel insulated against ground. Further there is a tower built of prefabricated concrete segments for mobile phone services close to the transmitter building.
All transmitters using the facility have a call sign starting with DCF. The best known of them is DCF77longwavetime signal and standard-frequency radio station. In earlier times the facility was also used for longwave broadcasting, especially as backup transmitter for Sender Donebach.
A radio clock or radio-controlled clock (RCC), and often (incorrectly) referred to as an atomic clock is a type of quartz clock or watch that is automatically synchronized to a time code transmitted by a radio transmitter connected to a time standard such as an atomic clock. Such a clock may be synchronized to the time sent by a single transmitter, such as many national or regional time transmitters, or may use the multiple transmitters used by satellite navigation systems such as Global Positioning System. Such systems may be used to automatically set clocks or for any purpose where accurate time is needed. RC clocks may include any feature available for a clock, such as alarm function, display of ambient temperature and humidity, broadcast radio reception, etc.
The Warsaw Radio Mast was a radio mast located near Gąbin, Poland, and the world's tallest structure at 646.38 metres (2,120.7 ft) from 1974 until its collapse on 8 August 1991. Designed by Jan Polak, and one of the last radio masts built under Communist rule, the mast was conceived for height and ability to broadcast the "propaganda of the successes" to remote areas such as Antarctica. It is the second tallest structure ever built, being surpassed as the tallest by the Burj Khalifa tower in the United Arab Emirates, completed in 2009.
The longwave transmitter Raszyn is a longwave broadcasting transmitter near Raszyn, Poland. It was built in 1949. The designer of the mast is unknown. It has been claimed that it was built of sections from radio mast of former Deutschlandsender Herzberg/Elster; however, there is no proof of this theory. The mast of the Raszyn longwave transmitter was, at inauguration, the second-tallest man-made structure on earth and until 1962, with a height of 335 metres, the tallest structure in Europe. Tower Height is 1099 feet/335 meters tall.
The Roumoules transmitter is the main broadcasting facility for longwave and mediumwave broadcasting of Radio Monte Carlo near Roumoules, France and is owned by Monaco Media Diffusion. The 1000 and 2000kW transmitters installed are among the most powerful in the world and can be received well at nighttime throughout Europe.
The Mühlacker Broadcasting Transmission Facility is a radio transmission facility near Mühlacker, Germany, first put into service on November 21, 1930. It uses two guyed steel tube masts as aerials and one guyed steel framework mast, which are insulated against ground. It has two transmission aerials for shortwave and one free standing steel framework tower for directional radio services. The shortwave transmitter was shut off on October 19, 2004. The medium wave transmitter was switched off in January 2012.
The Westerglen transmitting station is a facility for longwave and mediumwave broadcasting established in 1932 at Westerglen Farm, 2 miles (3 km) south west of Falkirk, Stirlingshire, Scotland.
Kalundborg Radio is a major transmission facility for long- and mediumwave at the harbour of Kalundborg in Denmark.
The Transmitter Ismaning was a large radio transmitting station near Ismaning, Bavaria, Germany. It was inaugurated in 1932. From 1932 to 1934 this transmitter used a T-antenna as transmitting antenna, which was spun between two 115-metre-high free-standing wooden lattice towers, which were 240 metres apart. As this antenna had an unfavourable vertical radiation pattern, which produced much skywave resulting in a too small fading-free reception area at night, in 1934 a new antenna was installed. Therefore, one of the towers was dismantled and rebuilt on a 39-metre-high (128 ft) wooden lattice base. While this work took place, an L-Antenna was used, which was spun between the other tower and a small auxiliary wooden tower. It became defunct in 1977 and was destroyed in 1983.
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 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.
The Mainflingen mediumwave transmitter is a mediumwave transmission facility south of the A3 motorway near Mainflingen, Hesse, Germany. Mainflingen was the first mediumwave transmitter for the radio station Deutschlandfunk. It went into service in 1962 with a transmission power of 50 kW, on a frequency of 1538 kHz, at the upper end of the mediumwave band. This frequency has a bad groundwave propagation and therefore a low range at daytime, but an excellent skywave propagation with a long range at night.
The Monte Ceneri transmitter was first established as the nationwide medium-wave radio transmission station for Italian-speaking Switzerland in 1933. Located on Monte Ceneri in Ticino, it broadcast on a frequency of 558 kHz.
The Erching transmitter was a longwave broadcasting facility of the Voice of America, established in 1953 near Erching, Bavaria, Germany. The transmitter used a 256-metre-high (840 ft) guyed-steel-framework mast aerial, at the time of its inauguration the most powerful radio station in the world, with a transmitting power of 1000 kilowatts on 173 kHz.
Transmitter Koszęcin is a facility for mediumwave and FM broadcasting near Koszecin, Poland. It was opened in 1977. It has two guyed masts: the first one is 110 metres high, is grounded, and carries antennas for FM broadcasting ; the second is 138m high. That second mast is insulated from ground and used for mediumwave transmission; broadcasting of the Radio Pahonia in Belarusian is planned on 1080 kHz with ERP 350 kW using this mast. The signal will cover the whole of Europe including the Ural Mountains. Earlier, the AM Mast was used for Polish Radio and used two Tesla transmitters 750 kW each in parallel. With the transmitted power of 1500 kW it was one of the most powerful mediumwave transmitters in the world.
