We all love the feeling of becoming the first person to activate a POTA or SOTA site.  Well, now there is a free tool to help you find those sites local to you which are ripe for activation. Released by the World Radio League, this web application tracks POTA, WWFF, IOTA & SOTA. Simply provide location permissions, and you are presented with a map of local sites.  The ones in red have never been activated. Have you any sites near you which have never been activated?  Let us know. https://app.worldradioleague.com/activities
