Cremlingen Transmitter
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 first transmitter was installed in 1962. It transmitted the program of Deutschlandfunk on 755 kHz (756 kHz from 1978 on) at a power of 100 kW and used as its aerial a 137-metre-high Guy-wire, guyed steel framework Radio masts and towers, mast. The transmitter power was raised to 200 kW one year later, but it only operated during daytime for some time. Interferences with the Ravensburg mediumwave transmitter which worked on the same frequency were common. A second transmitter was installed for the transmission of the Deutschlandfunk programme on 548 kHz from 28 October 1963, initially with a power of 200 kW. It used a 240-metre-high guyed steel tube mast as its aerial, which was insulated agains ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mediumwave
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
