Learn Morse Code
Dots, Dashes, Timing, and Real Practice
Start with the timing rules of dots and dashes, then move to letters, numbers, abbreviations, and real words. This page is designed as a practical learning path for beginners.
1. Morse Basics
Dot (.)
A dot is the shortest Morse signal and lasts for one time unit. For example, the letter E is a single dot.
Dash (-)
A dash is a longer signal and lasts for about three time units. For example, the letter T is a single dash.
Timing Rules
- · Between symbols (dot/dash): 1 unit
- · Between letters: 3 units
- · Between words: 7 units
Why only dots and dashes?
Morse code is a binary-style system: every character is a unique sequence of short and long signals. With just two symbols, you can build 2, 4, 8, 16, 32… different combinations as the sequence grows, which is more than enough to cover the alphabet, numbers, and punctuation.
2. Memory Tips
Start with E and T
E is a single dot and T is a single dash. Once you know the shortest two signals, the rest of the alphabet feels much less abstract.
Use Number Patterns
Numbers always use five signals. 1-5 begin with dots, 6-9 begin with dashes, and 0 is five dashes.
Learn in Pairs
Some letters are easier when paired together, such as A/N, D/U, and B/V. Reversed rhythm often means related memory.
3. Letters A-Z

4. Numbers 0-9
Numbers are shown here as a quick preview. Open the dedicated numbers page if you want the full learning notes and number-sequence examples.

Once letters are familiar, switch to complete words and radio shorthand. This is where Morse starts becoming practical.
SOS Distress Signal
SOS (... --- ...) is the universal distress signal. It is simple, easy to recognize, and usually sent as one continuous signal.

6. How Morse Code Timing Works
Pick a character and watch the signal build up in real time. The same rules — dot = 1 unit, dash = 3 units — apply to every character you send.
Watch how the signal lights up in sequence: each dot occupies 1 time unit and each dash occupies 3 units, with a 1-unit pause between symbols inside the same character.

8. Learning Path
- 1. Memorize E, T, A, N, I, M first, then expand outward.
- 2. Learn all numbers 0-9 using the five-signal rule.
- 3. Practice SOS, HELP, CQ, and QSL until you can recognize them instantly.
- 4. Move on to full words and short phrases, paying attention to spacing between words.
