Prefix OS
Belgian individual operators and radio clubs are authorized to replace their ON prefix with OS between 18 April and 12 December. This is to celebrate World Amateur Radio Day (18 April) and the 120th anniversary since Guglielmo Marconi's first reception of transatlantic radio signals (12 December 1901).
