100 Jahre SAQ VLF-Transmitter in Grimeton

The Alexander Association welcomes all visitors to the Alexanderson Day, Sunday, June 30th, 2024, 09:30-16:00. Together with the World Heritage Grimeton Radio Station, we will offer many activities, for the whole family, during the day. The unique Alexanderson alternator from 1924, with the call sign SAQ, is scheduled for two transmissions over the antenna on VLF 17.2 kHz CW.

Almost a hundred years ago, on December 1st, 1924, the long wave transmitter at Grimeton Radio Station, with the call sign SAQ, was put into commercial operation, with transmissions across the Atlantic ocean, to the receiving station in Riverhead and with the replying transmitter station in Rocky Point, both on Long Island, NY, USA. While all the other transmitting and receiving stations in the RCA network since long are gone, SAQ has been preserved as a World Heritage Site and, amazingly, SAQ is still operational. The design and manufacturing of such a robust a reliable radio transmitter was a monumental achievement by the Swedish-born inventor Ernst F.W. Alexanderson.
Thank you Ernst!
