Before you start
- Untimed. The explanation appears as soon as you answer, because the point here is to learn rather than to score.
- Mark an answer as a guess and it enters your review queue even if it happened to be right.
- Every answer moves your ability estimate for that topic and updates your readiness score.
- Retake as often as you like.
Sample questions
Which Morse character is a single dot?
- E
- T
- I
- A
Why E is right: E is a single dot and T is a single dash — the two shortest characters, assigned to the two most common letters in English.
In standard Morse timing, how long is a dash relative to a dot?
- The same length
- Twice as long
- Three times as long
- Five times as long
Why Three times as long is right: A dash is three dot-lengths. The gap between symbols within a character is one dot, between characters three dots, and between words seven dots.
The standard word used to define Morse sending speed is:
- MORSE
- PARIS
- CODEX
- SPEED
Why PARIS is right: PARIS is exactly 50 dot-lengths including the trailing word space, so sending it ten times in a minute is 10 words per minute. One dot length equals 1.2 ÷ WPM seconds.
