SAQ 17.2 kHz transmissions on Christmas Eve
The Swedish VLF transmitter SAQ at Grimeton will be transmitting on 17.2 kHz on Christmas Eve and you can listen on the web using the Delft VLF SDR.
They will start the transmitter at about 07:30 UTC for tuning for half an hour, then a message will be sent at 08:00 UTC on a frequency of 17.2 kHz CW.
The Varberg Radio Station at Grimeton in southern Sweden (built 1922–24) uses an Alexanderson Alternator and was added to the UNESCO World Heritage list on July 2nd 2004.
It is an exceptionally well-preserved monument to early wireless transatlantic communication consisting of the transmitter equipment, including the aerial system of six 127-m high steel towers. Although no longer in regular use, the equipment has been maintained in operating condition.
The 109.9 hectre site comprises buildings housing the original Alexanderson transmitter, including the towers with their antennae, short-wave transmitters with their antennas, and a residential area with staff housing.
The architect Carl Åkerblad designed the main buildings in the neoclassical style and the structural engineer Henrik Kreüger was responsible for the antenna towers, the tallest built structures in Sweden at that time. The site is an outstanding example of the development of telecommuni-cations and is the only surviving example of a major transmitting station based on pre-electronic technology.
