Radio Seagull on air: Sietse Brouwer Profile Sietse Brouwer Sietse first got involved in radio when he was only 14 years old. After that hospital radio, pirate radio (land based), community radio, regional radio and finally radio on a ship. Initially Sietse had a role within Radio Seagull as a presenter, however since the company who exploits Radio Seagull also started Radio Waddenzee and runs a radio ship as well, the hours in a day were no longer enough. As the member of the board who is responsible for radio Seagull, Sietse always stays in very close contact with Stevie Gordon and remains connected to the station. Sietse can be heard every Saturday 4-7 pm on Radio Waddenzee.
