Heusweiler radio transmitter
The transmitter Heusweiler is a medium-wave transmitter of the Saarland Radio north of Heusweiler. He was the most powerful medium wave transmitter of the ARD with a maximum transmission power of 1200 kW.
History
The transmitter Heusweiler went on 23 December 1935 in operation. He used in the early days of a T- antenna, which was suspended on each one 35 meters and a 31 meter high guyed wooden tower. On March 17, 1945, the transmitter was destroyed by enemy action.
On June 19, 1946 began in Heusweiler again the transmit mode. It has a T - antenna was first used, which has been replaced by a 50 meter high guyed, insulated against ground steel truss mast in the same year. This mast still exists today and is used as a reserve antenna. 1948 a 120 -meter-high, insulated against ground steel truss mast was erected as a transmitting antenna. In the period following the transmission power was increased continuously.
1965, a second transmission tower of 120 meters above sea level in Heusweiler was built in 1973 and increases the power to 1200 kW. However, the power was reduced to 600 kW in the night hours. The transmitter Heusweiler was thus the most powerful medium wave transmitter in Germany and the strongest stations of the ARD. From 1973 to 1994, the station was used for the dissemination of the program of Europawelle Saar of the Saarland Radio on the frequency 1421 kHz, and ( as of 23 November 1978) 1422 kHz, which was broadcast during the day with a capacity of 1200 and at night with 600 kW.
Since 1994, the program of the Germany radio is distributed via this channel. The transmission power is 600 kW since all day.
February 2008 was replaced by a transistorized system of Transradio SenderSysteme Berlin with a carrier power of 400 kW, the old tube station. The system is prepared for DRM operation.
The Saarland Radio has taken the end of 2005 in Heusweiler a second medium-wave transmitter for its Information Program antenna Saar in the daytime hours in operation. For this, the former Reserve end system for the frequency 1422 kHz is used. This program is broadcast on the frequency of 1179 kHz at a power of 10 kW. Since 2 November 2009, the station is available around the clock in operation.
Special
About the running in the immediate vicinity of the transmitters Federal Highway 8, a cable net that shielding to prevent interference in the 1970s to about half a kilometer length of the route.
Another special feature is the location beneath the station, now closed indoor swimming pool, which at that time was heated with the cooling water of the transmitter. The power reduction and various technical adjustments had helped that the water was no longer there as warm as before.
