This week I have discussed with Finnish Hammate who is local WWFF coordinator. WWFF areas and working rules I understand well (44 qsos instead of 4). Working Lighthouses and Castles (COTA) is also clear for me but GMA (Global Mountain Activity) makes me a bit confused.
Reading fast its rules I think it is quite same hobby as SOTA. Only difference seems to be how to define the height of summit. GMA has also own GMAwatch which is corresponding with SOTAWatch.
Could somebody tell me about the history and progress of these two associations (perhaps there is more)? Why is several corresponding associations for the same hobby? Which one has been founded first?
