Official transmissions

SändarstartGrimeton 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 twice a year: at the Alexanderson Day (Sunday at the end of June/beginning of July) and at Christmas Eve. The frequency is 17,2 kHz CW.

Find detailed information about coming transmissions under “Events” menu.



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. See Events menu for more information.

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.
