SAQ Transmission

Official transmissions

Grimeton Radio Station was listed as a world heritage site because its original equipment is an exceptionally well-preserved example of the development of communication technology. In fact, it is still in working order. Grimeton (call sign SAQ) still transmits a message to the world three times a year: at the Alexanderson Day (Sunday at the end of June/beginning of July), at the UN day (24 October) and at Christmas morning.

Additionally, the old transmitter is also turned on for the benefit of the general public several times a year.

Groups can also book an exclusive start-up demonstration as part of their visit to the world heritage site. Contact the World Heritage Grimeton for more information.


Alexanderson Day 2013

Alexanderson Day 2013 takes place on Sunday 30 June.

We will try to send a message with the old alternator at 09:00 UTC and 12:00 UTC. We start the transmitter about half an hour before we send the message. The frequency is as usual 17.2 kHz CW.

Unofficial transmissions

Unofficial transmissions may take place, due to maintenance, training or local events. Reports from unofficial transmissions are normally not confirmed by QSL cards.

Start of alternator without transmission

In summertime, the Alexander Society shows the alternator on Tuesday evenings, combined with a start of the alternator. On these events, there is no transmission from SAQ.
