The Alexander Association welcomes all visitors to Alexanderson Day, Sunday, July 3, 2022, 10-16.
After the pandemic restrictions of the last two years, we are happy to welcome all visitors again.
Together with the World Heritage Grimeton Radio Station, we will offer many activities, for the whole family, during the day.

We will make two transmitter startups with SAQ, but this year without any transmission over the antenna due to difficulties in obtaining components in the ongoing maintenance work.

Both transmitter startups will be broadcasted live via our YouTube channel,
This year we will give a more in depth technical presentation of the Alexanderson alternator during the startups.
