Welcome to the World Heritage Site Grimeton on July 2nd, 2025, to participate in the celebration of the 100th anniversary after King Gustav V officially inaugurated the Royal Telegraph Administration’s major investment in a Swedish longwave radio station.

The program for the day will be presented later, but we promise a wonderful, folk-oriented event.

During the anniversary day on July 2nd, we are planning for two transmitter launches with the transmission of a telegram via SAQ. Admission to the Transmitter Hall for these transmissions are at 10:00 and 14:00. For participation in the transmitter launches, 100 participant places are offered/occasion and ticket purchase is required for this activity.

All other activities on this day are free of charge.
The traditional Alexanderson Day is cancelled this year.

Please note! Grimeton Radio Station is both an old and active radio station, so planned transmissions may be cancelled at short notice.
