MB9BS 1951 Austria

According to Dokufunk web site:
"MB9BS was operated from a room near the laundry of the Klagenfurt Barracks, using mainly a dipole.
The favourite band of the time was 40 metres but 80 and 20 metres were also used.
The person who held the licence for MB9BS was Frank Sweet and I set up the club station and operated for just one year."
