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 guyed steel framework 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 against the ground, A second, insulated guyed steel framework mast was installed to shape the radiation pattern with a minimum towards the southeast, in order to avoid interferences with Radio Mayak in the Soviet Union.On 1 October 1967 the transmission power on 548 kHz was raised to 800 kW (400 kW during nighttime), sufficient to reach all of the northern Federal Republic of Germany and most of the territory of the GDR.
