Experience the wings of history where they are really heard!
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.
The unique Alexanderson alternator from 1924, with the call sign SAQ, is scheduled for two transmissions over the antenna on VLF 17.2 kHz CW.
To attend one of the transmissions in the transmitter hall, a ticket will be required.
You can book you ticket here already now (recommended).
A full program of all activities on the 2026 Alexanderson Day will soon be available on grimeton.org.

Live Video from World Heritage Grimeton Radio Station
On this Alexanderson Day there will be no live video from the transmissions, due to staffing difficulties. Instead, the Alexander association team will fully focus on bringing SAQ out in the ether.
We ask for your understanding.
Test Transmissions
We are planning for some test transmissions, preliminary on July 2nd or 3rd between 13:00 – 16:00 CEST (we will confirm as soon as we can). During the tests, SAQ will be on air shorter periods of time, when we will be carrying out some tests and measurements.
