Nauen Transmitter Station - History


Before World War I, the Nauen station was a research station of Telefunken. Trial service was initiated on 9 August 1906, and operational service began on 16 August 1906 using spark-gap transmitters. An umbrella antenna was supported by a steel lattice mast 100 metres high, insulated from earth.

Since the station had no commercial power, a 35 HP steam tractor was installed in the transmitter building, a light half timbered house, which powered a 50 Hz alternator producing 24 kVA output power.

Arc transmitters were installed in 1909, which increased the range of the station to 5000 kilometres.

A radio link with the German colony of Togoland was established for the first time in 1911. In the same year the antenna tower was increased to 200 metres in height; however, this tower was destroyed by a storm on 31 March 1912. A temporary replacement antenna was suspended between two 120 metres high masts. This was replaced by a V-shaped antenna supported by five masts at end of 1912. In 1913 the first high power machine transmitter was installed in the station. It worked with frequency doubling using the Arco system.

A large antenna, 1037 metres long, was installed on 10 February 1914 supported by a 260 metre mast and two 120 metre masts. A new modern transmitter building was also installed.

Famous quotes containing the word history:

    It is the true office of history to represent the events themselves, together with the counsels, and to leave the observations and conclusions thereupon to the liberty and faculty of every man’s judgement.
    Francis Bacon (1561–1626)

    The best history is but like the art of Rembrandt; it casts a vivid light on certain selected causes, on those which were best and greatest; it leaves all the rest in shadow and unseen.
    Walter Bagehot (1826–1877)

    In history the great moment is, when the savage is just ceasing to be a savage, with all his hairy Pelasgic strength directed on his opening sense of beauty;—and you have Pericles and Phidias,—and not yet passed over into the Corinthian civility. Everything good in nature and in the world is in that moment of transition, when the swarthy juices still flow plentifully from nature, but their astrigency or acridity is got out by ethics and humanity.
    Ralph Waldo Emerson (1803–1882)
