Find here on the BOS! Maps all ONFF, BCA, BLHA, GMA and SOTA references.
For ONFF activations, they must take place in the coloured area. For BCA activations, they must take place within the 1km radius of the reference.
Due to the huge amount of data, the maps are split up by the Belgian Provinces.
All maps are courtesy of ON5SWA (thanks for the never ending precious work)
