 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 UT on December 24 and
should be on air with a test signal from 07:40 UT. A message will be
sent at 08:00 UT 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 2, 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.
