How to Read Morse Code
Train your ears and eyes to recognize Morse Code faster.
Identify the code above to maintain your streak.
Choose the task you want to practice
Visual decoding asks you to identify a written pattern. Sound identification asks you to recognize an audio pattern. Use the sound exercise when your goal is receiving Morse by ear; use the visual exercise for checking notes, puzzles or written designs.
The current practice tool asks individual-character questions. It is not a complete progressive Koch course and does not supply an independent Farnsworth spacing control. The main translator can play custom words at a selected ordinary WPM, which gives you a separate way to check whole-message rhythm.
A short session with a clear result
Begin with ten questions. Listen to each character, answer before looking at the explanation, and note which characters you confused. Replaying a sound is useful during study; for a self-check, decide in advance whether a replay counts as an assisted answer.
If you confuse E and I, compare one dot with two. If you confuse A and N, listen to their order: short-long versus long-short. After reviewing the pair, attempt another small set. Track correct answers and assistance separately so repeated guessing does not look like reliable recognition.
End the session by playing a short known message in the translator. Write what you hear, then compare it with the original. This connects individual characters to the letter and word gaps that a longer message needs.
Use training methods accurately
Koch practice introduces a small character set at a chosen target character speed, adding characters as recognition improves. Farnsworth timing expands the spaces while retaining quicker character sounds. They address different aspects of practice and can be combined; neither guarantees a specific learning time.
Charts are useful for checking written code. For listening, try to recognize the complete sound rather than translate every mark visually. Choose a pace that lets you practice consistently, and use the ARRL resource list to find a trainer with the exact controls you need.
Progress varies with your goal and available practice time. Recognizing a familiar name, copying random letters and following a radio conversation are different tasks. Measure the task you are practicing rather than treat one good score as proof of proficiency in every setting.
The controls and feedback in this exercise
Choose a visible-code question or a sound question. Both modes ask you to enter the character represented; neither asks you to tap a transmitted message. Sound questions play at 20 WPM, and the listen button repeats the same character. The character pool contains letters and digits.
A correct answer adds 10 points and increases the streak, then a new character appears. A wrong answer resets the streak and shows the correct character; Try Another moves on. Record attempted questions separately if you want an accuracy percentage, because the on-screen score is points rather than a percentage.
A session you can record
| Step | Example | Record |
|---|---|---|
| Choose a pair | A and N | Which sounds you confuse |
| Listen before looking | Play one character; write your answer | Correct / attempted |
| Inspect the boundary | A is short-long; N is long-short | Direction of the confusion |
| Repeat later | Keep the speed and task the same | Whether the same mistake recurs |
Worked examples
These patterns use International Morse. Spaces separate letters; / separates words. A slash in the original text is encoded as -..-.
- HI
- Try this message
.... ..0.78 seconds at 20 WPM - ANNA
- Try this message
.- -. -. .-1.74 seconds at 20 WPM
