The transmitter station at Grimeton was taken into operation in 1924. It was built for wireless radio waves and was part of a worldwide net of long wave transmitting stations, all of them equipped with the revolutionary technics invented by the Swedish-American, Ernst F.W Alexanderson. Unique for Grimeton is that this station is the only one left today in this once global network. Which means that Sweden, Halland and Varberg can proudly present a technical heritage that does not resemble anything else, anywhere else - and that is still in operation.

The radio station's six masts are clearly visible from highway E6, east of the city of Varberg. From E6 take exit 54, then road 153 for approximately 5 kilometers, towards the town of Värnamo. After passing the church of Gödestad, turn right towards Grimeton, in the direction of the masts. After about 2 kilometers you will reach historic Grimeton.

Open 5th of July to 21st of August. Guided tours daily on the hour from 11 a.m to 5.00 p.m. Monday closed.

The "great radio station", as it was called, was built between the years 1922 and 1924. The transmitter, the heart of which is an alternating-currentgenerator (alternator) was developed by the Swedishborn engineer Ernst Alexanderson (1878-1975), who was a pioneer in radio engineering. Educated in Europe, employed at General Electric in Schenectady outside New York and later on the chief engineer at radio Corporation of America (RCA).

In autumn of 1923 the establishment, except the six antenna masts, was completed. The construction of the masts were delayed by a general strike at the Swedish ironworks. They were therefor built in 1924 as the last part of the installation. The six 127 meter high masts are still there. The masts were placed at 380 meter intervals and at the top of the 46 meter high masts, long crossarms were attached in order to carry the 12 wires feeding energy into the six vertical radiating elements.

The Swedish receiving stations for transatlantic wireless telegraph was built in Kungsbacka. Both the transmitting station in Grimeton and the receiving station were connected to the Göteborg Telegraph Station, where arriving and outgoing telegrams were dispatched.

In the summer of 1925 the formal inauguration of our Swedish transmitting station Grimeton, for wireless telegraph to America took place.
