I am shure that many of you know about Morse code in combination with flashing lights used by the Navy when radio silence is orderd. This way of communicating was common from around 1870 and up to the 1940's. It's still a very effective way of communicating. All you need is a flash light. Range can be up to 30 miles (at night). I searched a long time for a simulator program that could improve my morse lamp skills. I could't find any. So i made one my self. Here it is, and it's free ! http://home.no.net/fenja256/superaldis/
Thanks much js00 and welcome to Yacht Forums. With that alien invasion movie--'Fourth of July'-- in mind, you never know when the old skills will come in handy.
