Grimeton SAQ turns 100!

On July 2, 2025, the SAQ Grimeton Radio Station in Sweden celebrates its centennial — a hundred years of quiet transmissions that have bridged continents and eras.

Built in 1925, this UNESCO-listed radio station still transmits Morse code using a pre-electronic VLF generator.

A silent voice of peace across the globe.
