Torgeirs grandfather, Haakon Sørbye, studied electrical engineering and was a radio amateur. In 1940, in the beginning of WWII, he was recruited as a telegraph operator for the secret intelligence service station in Trondheim, Skylark B.
The station sent three times a week, all in code: military information on troop movements and ship calls, military and merchant vessels and other German activities. He was eventually arrested and sent to several German prison camps.
In Dachau, he managed to assemble a working radio receiver with radio parts that other prisoners had found. Among other things, the radio received Norwegian-language broadcasts from London and the Norwegian prisoners were kept informed about the course of the war in the winter and spring.
After the war, Haakon continued his studies before he worked years developing the radio line production in Norway.
