JN51XX
JN51 is one of the Most Wanted Squares in Europe on 144MHz and surely rare on 6m, too. 99% of this locator square is sea without islands and the 1% (JN51XX) is land shared by the military and a natural reserve.
With the help of local hams we got a permit to operate from a place in the natural reserve with limition of a daily operation from 6:30 - 17:30 UTC.
