FM broadcasting
VHF Radio waves do not travel far beyond the visual horizon, so reception distances for FM stations are usually limited to 30–40 miles (50–65 km) They can also be blocked by hills or buildings.
Raszyn radio transmitter
The longwave transmitter Raszyn was until the inauguration of Warsaw radio mast in Konstantynów the central longwave broadcasting of Poland.
Since 1978 from this facility during daytime a second program in the longwave range was transmitted on AM-LW (long wave)198 kHz/1515 meters (formerly the frequency was used by Radio Parlament).
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 (longwave) 225 kHz/1333 meters. Because it was not possible to transmit from Raszyn on both longwave frequencies of the Polish Broadcasting Company simultaneously, no transmissions on the second longwave frequency of the Polish Broadcasting Company (AM-LW 198 kHz/1515 meters) 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 (longwave) due to economical crisis, and the longwave transmitter has been turned off.
