Raszyn transmitter

The Raszyn transmitter is a long-wave radio transmission system near the village of Lazy, which belongs to Lesznowola (Poland).

It went into operation in 1931 with an output of around 120 kW as the most powerful transmitter in Europe. An increase in output to 600 kW was planned, but was no longer possible because of the Second World War. With the approach of the German Wehrmacht , Poland was forced to destroy the 280-meter-high mast used as an antenna support.

In 1945 the transmitter was rebuilt with around 500 kW.

Not too long afterwards, in 1949 a new 335-meter-high transmission mast, insulated from earth, was erected in Raszyn. At the time, it was the tallest structure in Europe.

The Raszyn transmitter was the location of the central long-wave transmitter for Polish radio until the transmitter in Konstantynów was commissioned in 1974.

From 1974 to 1978 it served as a reserve transmitter for this system. Since 1978, the Raszyn system has broadcast a second Polish radio program during the daytime in the long-wave range on the frequency of 198 kHz. After the mast in Konstantynów collapsed , the system was used to broadcast the first Polish radio program on the 225 kHz frequency until the new long-wave transmitter in Solec Kujawski was put into operation . Since it is not possible to transmit simultaneously on both longwave frequencies via the Raszyn transmitter, the second longwave frequency of the Polish radio was not used during this time.
