On the 5th of July 2026 the World Heritage Grimeton Radio Station and the Alexander Grimeton Friendship Association invite you to the Alexanderson Day – a unique and lively family day filled with technology, culture and world-class experiences.
During the day, the radio station is brought to life with the legendary Alexanderson Alternator (SAQ), the only one of its kind in the world that still works.

 

A full program of all activities on the 2026 Alexanderson Day will soon be available on grimeton.org.
