Official transmissions

Normally, SAQ sends out a message around the world twice a year: on Alexander Sunday (Sunday at the turn of the month June / July), and on Christmas Eve morning. The frequency is 17.2 kHz CW. Transmitter start takes place approximately 30 minutes before sending the message.
Additional transmissions may occur on special occasions.

Detailed information about upcoming transmissions is always published in advance on our website.

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 the Alternator without transmission

In summertime, the Alexander Society shows the alternator on Thursday 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.
