All radio telegrams were handled at the Radio Central in Gothenburg. The messages were punched on paper tapes. These were inserted in a machine called transmitter, that transferred the information on the paper tapes into morse code. This was sent from Gothenburg on a telegraph line along the railway, first to Varberg and then to Grimeton railway station, and after that over the fields to the radio station, where it actuated the first telegraph relay of SAQ.
