International Lighthouse and Lightship Weekend
The International Lighthouse and Lightship Weekend (ILLW) is an annual event held on the third full weekend of August each year. The event was started by John Forsyth and Mike Dalrymple who were members of the Ayr Amateur Radio Group in Scotland. The event has developed into an international gathering of amateur radio operators from an estimated 54 countries.
The objective of ILLW event is stated as "to promote public awareness of lighthouses and lightships and their need for preservation and restoration, to promote amateur radio and to foster International goodwill." A classic example of what should not be allowed to happen to a lighthouse is shown here on YouTube featuring the lighthouse remains on Culebrita Island  in Puerto Rico
The basic format of the event is that a local amateur radio club will set up a radio station either in, or near to, a lighthouse. They will then operate from that station over the whole or part of the weekend. The goal is to contact other amateur stations, particularly those operating from other lighthouse sites. Visiting public are invited to watch the operators and even use the equipment under supervision while visiting the lighthouse. YouTube has numerous video clips about the weekend which have been submitted by participants.
