Like all radio transmitting stations that apply for a licence to BIPT, amateur radio stations receive, along with their licence, a call sign to identify themselves on the waves. This call sign takes the form “ON” followed by a digit and two or three letters. For special events, the recognised radio amateur associations can ask, for all the Belgian radio amateurs, a licence to use a prefix other than ON. This prefix must be chosen among those assigned to Belgium, i.e. between ON and OT.
To commemorate the hundredth anniversary of the 1st World War, the UBA (Belgian Amateur Radio Society) asks that all radio amateurs can use the OP prefix (P for Poppies) during the month of November, from 2014 to 2018. The duration of this licence is limited in time so that special prefixes stay attractive.
