The Grimeton radio station, also known by its callsign SAQ, is the only remaining transmitter based on an alternating current generator. It has been added to the UNESCO World Heritage list in 2004 and is still in full working condition. Originally built in 1922-1924 for wireless telegraphy to North America and other countries, the station is nowadays started once a year in the Alexanderson day (the Sunday closest to 2 July) and used to transmit a CW message. Sometimes messages are transmitted on other days such as Christmas Eve.
SAQ shares its antenna with the Swedish navy which operates SAS/SRC at 40.4 kHzKiloHertz (kHz) 10^3 Hz at the same site (Varberg). So SAS/SRC is always turned off when SAQ is on air.
