[2][4] The station was also used for the contact with Sveagruva on Svalbard and for radiotelegraphy with ships in the Gulf of Bothnia.

[4] At 15:00 local time on 12 July 1921,[6] the first radio broadcast in Swedish history was sent from the bunker.

[3] Radio commissioner Axel Jenner conducted this historic broadcast, with the Swedish king Gustav V listening some 35 km away in Luleå.

[2] Due to a misunderstanding between Jenner and his radio telegrapher, the first words uttered in the broadcast were "jävlar anamma",[2] a Swedish profanity in the style of "damn" or "darn", literally meaning "embrace the devils".

The bunker was put out of operation 1 January 1975 and ten years later in 1985, it was decommissioned by the Swedish Army.
