The longwave transmitter Raszyn is a longwave broadcasting transmitter near Raszyn, Poland. It was built in 1931 and rebuilt in 1949. The designer of the mast is unknown. It has been claimed that the rebuilt tower consists of sections from the radio mast of former Deutschlandsender Herzberg/Elster; however, there is no proof of this theory. The mast of the Raszyn longwave transmitter was, at inauguration, the second-tallest man-made structure on earth and until 1962, with a height of 335 metres (1,099 feet), the tallest structure in Europe. The tower's height is 1,099 feet (335 meters).
The longwave transmitter Raszyn was until the inauguration of
Since 1978 from this facility during daytime a second program in the longwave range was transmitted on AM-LW (long wave)198 kHz/1,515 meters (formerly the frequency was used by Polskie Radio Parlament ). After the collapse of
The radio mast of the longwave transmitter Raszyn is since the collapse of the Warsaw radio mast the sixth tallest structure in Poland. On July 31, 2009, Polish Radio Parlament on has discontinued their broadcast on AM-LW (longwave) due to the Great Recession, and the longwave transmitter has been turned off.
The place was actually used for transmitting purposes from 1931 when the then Polish Radio Co. opened their new, modern 120 kW transmitter that was using two 280 m (920 ft) tall guyed steel lattice masts to support a T-shaped antenna. In the late 1930s works started to increase the output power to 600 kW but the works were not completed before start of the World War II. One of the masts was destroyed by Polish Army engineers to prevent the Germans from using the station.
Trivia: for a very short time after opening their new transmitting facility in 1931 the official Polish Radio Co. announcement was 'Halo, tu Polskie Radio Raszyn' ('This is the Polish Radio Raszyn'), but because Polish pronunciation of 'Raszyn' is nearly identical to English pronunciation of 'Russian' and therefore was confusing foreign listeners, the announcement was promptly changed back to 'Halo, tu Polskie Radio Warszawa' ('This is the Polish Radio Warsaw') (source: Maciej Józef Kwiatkowski 'Tu Polskie Radio Warszawa', Warsaw 1980).
