Emergency Signals

Emergency and distress vocabulary is where Morse code earns its reputation. SOS (...---...) has been the international maritime distress signal since 1906, chosen for its unmistakable rhythm rather than what the letters stand for. The Titanic transmitted both the older CQD and the new SOS on April 15, 1912, marking the moment the new signal became universal. Words like help, mayday, rescue, danger, and fire in Morse are core skills for survival training, scout signaling, and emergency-preparedness drills. Every entry in this group is fast to send and acoustically distinctive, which is exactly why Morse remains a backup communication standard in maritime and aviation regulations.
