The mediumwave transmitter Flevoland (Middengolf Zendstation Flevoland) was a broadcasting facility for medium wave near Zeewolde in the province of Flevoland, Netherlands, situated at 5°25′ E and 52°23′ N. It has been used for broadcasting on 747 kHz (until September 2015) and 1008 kHz with a nominal power of 400 kilowatts. As aerial two guyed steel framework masts with a height of 195 metres are used, which form an anti-fading aerial. These masts are grounded and carry a cage aerial, which is upperward the separation insulator, separating the masts in a height of 95 metres in two parts, connected toward the mast construction. The radiation diagram is directional, with a maximum gain of 4 dB in South-Eastern direction, to compensate for the variation in electrical admittance of terrain in the Netherlands.
The Mediumwave Transmitter Bremen is the mediumwave broadcasting facility of Radio Bremen situated at Bremen-Oberneuland, Germany. It operates at 936 kHz, with a transmitter output power of 50 kW. The new transmitter at Bremen-Oberneuland was built in 1999 as a replacement for the old transmission facility of Radio Bremen at Leher Feld, which was demolished to make room for an industrial area.
Originally, there was also a second, 165 metre guyed steel framework mast for the mediumwave frequency 1332 kHz, but this was taken down on 21 August 2004.
For MF / Mediumwave, the BBC defines the daytime service area boundary as a minimum field strength of 2 mV/m. At night, the service area of mediumwave services can be drastically reduced by co-channel interference from distant stations.
Today the mediumwave transmitter Bremen is the only transmitter owned by Radio Bremen — all other transmitters now used by Radio Bremen are the property of Deutsche Telekom — uses a cage aerial, mounted on a 45-metre (146 feet) high, grounded, guyed lattice steel mast. This aerial has a high gain of 4.5 dB, which means that the 50 kW transmitter feeding it produces the same effect as a 140 kW transmitter feeding an antenna with a gain of 1 dB.
On 9 January 2019 the masts were demolished with explosives, marking the definitive end of mediumwave broadcasting from this location. This was the last large mediumwave transmitter in The Netherlands, marking the end of a 90-year era of mediumwave broadcasting.
The Mediumwave transmitter Lopik was a medium wave broadcasting facility near Lopik in the Netherlands. It was constructed in 1938 and closed down on 1 September 2015. Its last use was to transmit the Dutch language edition of Radio Maria on 675 kHz. The aerial consisted of a 196-metre guyed steel framework mast, which was insulated against ground.
The Voice of Han also broadcasts propaganda programs to Mainland China on shortwave and mediumwave frequencies under the callsign "Voice of Guanghua" (光華之聲). Major programs include: Taiwan New Paradise, Music, Guanghua News, Guanghua Talk Forum, Culture and Education Filling Station, Two sides of the Taiwan Strait, Freedom Scene, Literature Bridge, Taiwan Strait Flyover, and Lookout Tower. *Mainland China: 801 kHz, 846 kHz, 711 kHz, 981 kHz, 9745 kHz, 6105 kHz
Near Szombathely, there is since 1955 at 47.20056°N, 16.66194°W a mediumwave broadcasting station operated on 1251 kHz with 25 kW, which uses as antenna two 60 metres tall free-standing radio towers insulated against ground. It is the only mediumwave broadcasting station in Hungary using free-standing self radiating towers.
Most radio receivers in the world receive the mediumwave band (530 kHz to 1710 kHz), which at night is capable of reliable reception from 150 to 2,500 km distance from a transmitter. Mediumwave is used heavily all over the world for international broadcasting on a formal and informal basis.
Sahlenburg Marine Radio Station was a facility of Elbe-Weser Radio in Sahlenburg, an urban part of Cuxhaven, Germany, for marine radio service in short- and mediumwave range. Sahlenburg Marine Radio Station used first a triangular antenna, which was fixed on three guyed wooden masts, each 40 metres tall, which were erected in 1929.
Heiligenstock Transmitter, also known as the Heiligenstock Radio Tower, was a wooden German lattice transmitter that was used for mediumwave broadcasting. The tower was built in the year 1934 but was dismantled four years later because of its bad state. The tower was then rebuilt the same year it was dismantled in the city of Frankfurt. The newly rebuilt radio tower was then demolished in March 25, 1945 during the second world war by the retreating German troops using explosives. It was 107 metres tall.
There are two abandoned high power mediumwave broadcasting facilities, situated at Encamp and on Pic Blanc.
The Lisnagarvey transmitting station is a facility for mediumwave broadcasting located in the townland of Magherageery, on the southern edge of Lisburn, Northern Ireland. It is close to Sprucefield shopping centre and about one mile from the middle of Lisburn.
Kalundborg Radio is a major transmission facility for long- and mediumwave at the harbour of Kalundborg in Denmark.
The AM expanded band, or "X-Band" as MW DXers often call it (not to be confused with the range of microwave frequencies), runs from 1610 kHz to 1710 kHz. This is a relatively new portion of the mediumwave broadcast spectrum, with the first two applications for frequencies having been granted in 1997. The lower density of stations in this area of the spectrum, as well as a lack of stations with more than 10 kW of power in the United States, has led to many DX'ers taking interest here.
The programmes of BBC Bangla are broadcast on FM radio, mediumwave and shortwave, their website and their internet radio and video services. BBC Bangla reaches 13,000,000 Bengali speaking people. Its radio and online services have listeners from many Bengali communities including those in Bangladesh, West Bengal, Tripura and Assam.
Its to be noted that Northants 96 and Northants Radio were interchangeable names for the station and relayed programmes on a mediumwave frequency – 1557 kHz, which opened on 25 June 1990.
The height of the mast determines the radiation properties. For high power transmitters in the MW range, masts with heights around half of the radiated wavelength are preferred because they focus the radiated power better to the ground than structures with heights of quarter wavelengths, which are preferred for economical reasons for low power medium wave transmitters. A focus of radiated power towards the ground is much desired on frequencies below 3 megahertz, because groundwave propagation is very stable. Masts longer than five eighths of the wavelength are normally not used, because they show bad vertical radiation patterns, so masts for mediumwave transmitters do not normally exceed 300 metres. For longwave transmitters, however, the construction of masts with heights of half-wave wavelength is generally not economically viable and in most cases impossible. The only longwave radio mast with a height of the half length of the radiated wavelength was the Warszawa Radio Mast at Konstantynów, Poland. At the time of its collapse in 1991 it was the tallest manmade structure in the world, at 646.38 metres (2,120.67 ft) tall, for a wavelength of 1292.76 metres (frequency 232 kHz). For frequencies below longwave, masts are electrically enlarged by loading coils or capacity hats on the top, because masts of even quarter wavelength would be too high to be practical.
Radio broadcasting began in 1936, with the Burma Broadcasting Service beginning operation ten years later. Today there are several FM stations, three mediumwave stations and three shortwave stations. The short and medium wave stations are all operated by MRTV or the military. The main radio stations are Radio Myanmar (operated by MRTV), Cherry FM, Mandalay FM, FM Bagan, Padamyar FM, Pyinsawaddy FM, Shwe FM and City FM. Radio Myanmar usually begins daily with readings from the governments' "Seven Point Road to Democracy", "Twelve Political, Economic and Social Objectives" and "Three Main National Causes".
