What is Morse Code?
Morse code is a system of encoding text characters as sequences of dots and dashes. Developed by Samuel Morse and Alfred Vail in 1838, it was originally transmitted using telegraph technology. Each letter, number, and punctuation mark has a unique pattern of dots (represented as •) and dashes (represented as −), separated by spaces.
History of Morse Code
- 1838: Morse code created by Samuel Morse and Alfred Vail
- 1844: First long-distance telegraph message sent: "What hath God wrought"
- 19th-20th Century: Became the standard for maritime and military communications
- SOS Signal: Famous distress signal transmitted in Morse code
- Modern Era: Still used in amateur radio (ham radio) and aviation
Morse Code Basics
- Dot (•): Short signal, represented as a period in text
- Dash (−): Long signal, represented as a hyphen in text
- Space: Separates letters and words
- International Standard: The dot-dash patterns are standardized worldwide
- Audio/Visual: Can be transmitted via sound, light, or radio waves
Modern Uses of Morse Code
- Amateur Radio (Ham Radio): Still widely used by hobbyists worldwide
- Aviation: Aircraft navigation beacons transmit identification in Morse
- Maritime: Emergency and distress signals use Morse code
- Military: Used in certain military communications
- Education: Taught as history and technical skill
- Accessibility: Used by people with communication disabilities
Fun Facts About Morse Code
- The letter E (•) is shortest, while O (−−−) is longest in Morse code
- The famous SOS signal (•••−−−•••) doesn't stand for "Save Our Souls" but was chosen for its distinctive pattern
- Morse code is still required for earning certain amateur radio licenses
- It takes about 3-5 weeks of practice to become proficient at Morse code
- Morse code was the precursor to modern binary code used in computers
