Background
The universal distress signal
SOS became the international distress signal in 1905 and was written into global radio regulations in 1908. It was picked not for its letters but for itsunmistakable rhythm: dot-dot-dot dash-dash-dash dot-dot-dot, run together without the usual gaps between letters so it reads as a single, continuous call for help.
You can send it with anything that switches on and off — a flashlight, a mirror, a whistle or a radio key. Send three short, three long, three short, pause, then repeat. Because it is a genuine emergency signal, only use SOS when real help is needed.
