Medium wave. Medium wave (MW) is a 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 ...
All three transmitters carry Radio teleswitch PSK data; Droitwich relays BBC World Service from 01:00 to 05:20 UTC. On 30 May 2023, the BBC announced that BBC Radio 4 will stop broadcasting on long wave but did not set a date. Opt-out programming ended on 31 Mar 2024.
Tuning dial on 1946 Dynatron Merlin T.69 console radio receiver, showing LW wavelengths between 800 and 2000 metres (375–150 kHz). In radio, longwave, long wave or long-wave, [1] and commonly abbreviated LW, [2] refers to parts of the radio spectrum with wavelengths longer than what was originally called the medium-wave broadcasting band.
The radio spectrum is the part of the electromagnetic spectrum with frequencies from 3 Hz to 3,000 GHz (3 THz). Electromagnetic waves in this frequency range, called radio waves, are widely used in modern technology, particularly in telecommunication. To prevent interference between different users, the generation and transmission of radio ...
AM broadcasting is radio broadcasting using amplitude modulation (AM) transmissions. It was the first method developed for making audio radio transmissions, and is still used worldwide, primarily for medium wave (also known as "AM band") transmissions, but also on the longwave and shortwave radio bands.
This is the origin of the terms long wave, medium wave, and short wave radio. [51] Portions of the radio spectrum reserved for specific purposes were often referred to by wavelength: the 40-meter band, used for amateur radio, for example. The relation between wavelength and frequency is reciprocal: the higher the frequency, the shorter the wave ...
Roumoules radio transmitter. Coordinates: 43°47′39″N 6°09′05″E. The Roumoules transmitter is the main broadcasting facility for longwave and mediumwave broadcasting of Radio Monte Carlo near Roumoules, France [1] and is owned by Monaco Media Diffusion. The 1000 and 2000kW transmitters installed are among the most powerful in the world ...
