Raszyn radio transmitter
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, the tallest structure in Europe. The tower's height is.
The longwave transmitter Raszyn was until the inauguration of Warsaw radio mast in Konstantynów the central longwave broadcasting facility of Poland.
Since 1978 from this facility during daytime a second program in the longwave range was transmitted on AM-LW 198 kHz/1,515 meters.
After the collapse of Warsaw radio mast in 1991 this facility was used until the inauguration of the new longwave-transmitter Solec Kujawski for transmissions of the first program of the Polish Broadcasting Service on AM-LW 225 kHz/1,333 meters. Because it has never been possible to transmit from Raszyn on both longwave frequencies of the Polish Broadcasting Company simultaneously due to its orientation towards the east and risk of interference, no transmissions on the second longwave frequency of the Polish Broadcasting Company took place between 1991 and 1999.
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 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 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', 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' .
