Set up a practice session
Enter the letters or digits you want to practise. The starting set ETIM gives four short, distinct patterns. Choose 10, 20 or 30 questions, then select a written or listening prompt. Press Start practice when you are ready.
Each question is selected randomly from your set. A character may appear several times, and a small session is not guaranteed to include every character. Repeated exposure is useful, but a single score should not be treated as a complete measure of proficiency.
Written and listening modes measure different tasks
Read Morse shows a dot-and-dash group and asks for its character. Listen to Morse hides the symbols; press Play prompt again to hear the signal, then type the letter or digit you recognize. You can replay a listening prompt before checking the answer.
The answer is shown only after you select Check answer. Next question stays disabled until the current attempt is checked. Enter submits your answer. The quiz counts each question once, so pressing Check repeatedly cannot increase the score.
Use a score to choose your next exercise
| Illustrative result | Interpretation | Possible next step |
|---|---|---|
| 6/10, with I missed repeatedly | A particular character needs attention. | Compare E and I, then repeat a shuffled set. |
| 9/10 written, 5/10 listening | Visual recall is stronger than audio recognition. | Keep the same set and practise listening. |
| Two comfortable sessions | The current set may be becoming familiar. | Add one or two letters and keep the earlier set. |
These are examples, not learner study results or universal advancement thresholds. Record what you find difficult. A total score can hide the fact that the same character was confused every time.
A manageable progression
- Start with
ETIM. - Add
AN, thenSO, when the first patterns become recognizable. - Mix in more letters using the alphabet reference.
- Practise numbers as a separate set, such as
1560, before combining them with letters. - Move to short words in the audio player.
This is one adaptable sequence, not a standardized course. The quiz supports Latin A–Z and digits 0–9. It does not test Arabic letters, punctuation, transmission technique or radio procedure. Use the language-specific reference pages for their supported mappings.
Keep a simple progress record
Write down the date, character set, prompt mode, score and missed characters. Compare sessions with similar settings. Changing the set, prompt type and session length together makes it harder to explain why the score changed.
Scores stay in this page session. Reloading the page resets them, and no account or long-term leaderboard is provided. If you need a durable record, keep your own notes. The learning guide includes a worksheet and a longer routine you can adapt.
When practice feels difficult
Reduce the character set rather than guessing through many unfamiliar prompts. Review the correct pattern after a mistake, then try it in a new order. If you can recognize individual letters but lose words, focus on short groups and their gaps instead of adding more letters immediately.
