Morse Code Sprint
Type the correct Morse code for the character shown. Use "." and "-" on your keyboard.
Play one 60-second round
Press Start Game, then enter the International pattern for the displayed letter or digit. Use the dot and dash buttons, or the keyboard. A correct answer adds 10 points and advances after a short pause; a wrong answer is cleared so you can try the same character again. There are no score multipliers.
The answer is checked when it reaches the expected pattern length. Backspace removes a mark before checking; after feedback appears, wait for the input to reset. The timer continues while you answer. Play Again starts a fresh round after the timer ends.
What your score measures
This exercise asks you to turn a visible character into written marks. For example, seeing A should lead you to enter its two-mark dot-dash pattern. The brief audio after a correct answer lets you check the sound, but your score does not measure receiving Morse by ear or transmission WPM.
Compare rounds with similar conditions: the same controls, whether you used a chart, and any distractions. Write down a confused pair such as A/N or P/L and study it before another round. Use the listening exercise for sound identification rather than treating a high sprint score as a radio qualification.
