We had a 5-watt capacity [transmitter], the size of a cigarette pack. The antenna was made of glued aluminium stripes on the cover sheet of a tent and we could fold it all in a little backpack. We would go to one of the hills surrounding Graz. We knew that it would take the legal body controlling the radio waves 20 minutes to come to the place where we were. We knew we had about 18 minutes of broadcasting, so we made 18-minute radio shows.
