About Morse Code Abbreviations
- •Q-codes (like QTH, QSL) are standardized three-letter codes used in amateur radio
- •Prosigns (like AR, SK, BT) are procedural signals that control the flow of communication
- •Number codes (73, 88) are traditional ham radio greetings and sign-offs
- •SOS (...---...) is the internationally recognized distress signal
Essential Morse Code Emergency Signals and Amateur Radio Abbreviations
Learn the most critical Morse code abbreviations used in emergency communications and amateur radio operations.
Critical Emergency Signals:
Distress & Emergency:
- • SOS in Morse code: "...---..." (international distress)
- • Transmitted as three dots, three dashes, three dots
- • No spaces between letters for emergency
Operational Signals:
- • CQ in Morse code: "-.-. --.-" (calling any station)
- • QRT in Morse code: "--.- .-. -" (stop sending)
- • Used by ham radio operators worldwide
Ham radio operators worldwide rely on these standardized abbreviations for efficient communication during emergencies, contests, and daily operations.
