Understanding Morse Code
Morse code is a character encoding scheme that transmits text information as a series of on-off tones, lights, or clicks. Invented by Samuel Morse and Alfred Vail in the 1830s, it revolutionized long-distance communication.
The 5 Timing Rules
- Dot (.): 1 unit of time
- Dash (-): 3 units of time
- Intra-character gap: 1 unit (space between parts of the same letter)
- Character gap: 3 units (space between letters)
- Word gap: 7 units (space between words, often written as /)
Common Codes
💡 Expert Tip: Listen to the Rhythm
Don't try to count dots and dashes visually. Morse code is an auditory language. Learn the sound of each letter. For example, 'C' (-.-.) sounds like "DAH-dit-DAH-dit". Experienced operators hear whole words, not individual letters.
⚠️ Common Mistake: Ignoring Spacing
Spacing is critical. "E E" (. .) is very different from "I" (..). Without proper spacing between letters (3 units) and words (7 units), the message becomes an unintelligible stream of beeps.

Frequently Asked Questions
What is Morse Code?
A method of encoding text as sequences of dots (short) and dashes (long). It was the primary method of long-distance communication for over a century.
What is the Morse code for SOS?
SOS is ... --- ... (three dots, three dashes, three dots). It is a continuous signal with no letter gaps, chosen for its distinctiveness.
How can I learn Morse Code quickly?
Listen to the rhythm. Don't count dots. Use the "Farnsworth method" where characters are sent fast but with long spaces between them.
Is Morse Code still used today?
Yes, by amateur radio operators, aviation navigation (VORs), and as an assistive technology. It's also a great survival skill.
