I am a little late in reporting this because I just learned about it.
A 2-day ham radio event will take place starting Saturday, August 20 at 0001 UTC and will continue through Sunday, August 21 at 24000 UTC.
Approximately 500 amateur radio stations will be operating from lighthouses and lightships to celebrate International Lighthouse Lightship Weekend (ILLW). There will be over 40 countries around the world lighting up the airwaves from these light stations.
If you miss the 2016 event do not despair because it will happen again next year and again the year following. The International Lighthouse Lightship Weekend Ham Radio Celebration happens each year on the third weekend of August.
