Solved
for Aifon Isle in useless. I've never seen it close enough to land to be worked. It could happen (not sure though) but it's so marginal it's really not useful. I'm an OO enthusiast, so it's a bit disappointing not to have a UF boosted... The thing being that there is few OO UF I can think of...
