Morse Code Quiz: Listen and Identify
The single habit that separates people who know morse code from people who read about morse code: hearing a character and naming it instantly, with no counting. This quiz drills exactly that. It plays one character — letter or digit — and you pick what you heard. Ten minutes a day beats an hour of staring at the chart.
How to use this quiz well
- Start with the Starter 9 set (E T A N I M S O H). These are the highest-frequency letters, and mixing just nine characters keeps every question answerable while your ear calibrates.
- Keep speed honest. Set a WPM where answers feel 80% confident — that's the growth zone. Slower than that teaches counting; faster teaches guessing.
- Use the Missed list. After each run, the characters you missed appear with their codes — those are your next drill set. Miss the same letter twice in a week? Play it ten times in the translator while saying its name aloud.
- Graduate by set, not by mood. 90%+ on Starter 9 → all 26 letters → letters + digits. The quiz is the gatekeeper for our Koch-method learning ladder too.
Why sound-first beats chart-first
Every experienced operator says it: morse is a language of rhythm, not shapes. If your path to a letter runs through "I hear di-dah → I picture · − → I translate to A", you'll plateau around ten words per minute, because the middle step is a bottleneck. Drills like this quiz delete the middle step: sound goes in, letter comes out. That's also why the quiz never shows you the code before you answer — your ears get no help from your eyes.

What speed should a beginner use?
Start at 10–12 WPM with Farnsworth-style gaps. Characters arrive at full speed (so you learn true rhythms) but with generous silence between them, which gives your brain time to respond.
How do I get past 90% on all 26 letters?
Stop adding and start separating: drill confusion pairs (like S/H, D/B, or mirror pairs A/N and D/W) in short focused runs using the translator's loop, then return to the full set. Most plateaus are really two or three lookalike characters dragging the average down.
