Morse Code Quiz
Test your Morse code skills by category. Decode visual dot-dash patterns or train your ears with live audio.
How to Play the Morse Code Quiz
Choose Your Category & Skill Level
Start with beginner-friendly ETAOIN letters, test the full Alphabet (A–Z), or challenge yourself with Numbers 0–9, procedural Prosigns, common Punctuation, or full Words.
Select Decode or Encode Mode
Toggle between Decode (Morse → Text) to identify characters from visual dots and dashes, or Encode (Text → Morse) to pick the matching dot-dash sequence for a shown character.
Listen to the Audio Rhythm
Click Play Audio on each question to hear the 680 Hz telegraph tone at standard ITU timing before answering. Learning the rhythmic cadence of dits and dahs is the fastest way to achieve fluency.
Learn from the Review Card
Get instant feedback on every choice. When the quiz ends, check the Questions for Review list to see any missed answers alongside their correct Morse patterns.
Quiz Tips
Master ETAOIN First
The letters E, T, A, O, I, and N make up over 50% of English text. Their short 1- and 2-symbol codes form the foundation of Morse code proficiency.
Keep Sessions Short
Choose the 5-question or 10-question sprint. Frequent, focused quiz sessions build faster muscle memory and auditory recall than long, exhausting marathons.
Train Your Ears First
Click Play Audio on every question before checking the answer choices. Internalizing the rhythm of dits and dahs by sound is 3× faster than visually counting dots.
Learn Mirror Opposites
Pair up inverse letters like A (· −) and N (− ·), D (− · ·) and U (· · −), and B (− · · ·) and V (· · · −). Remembering them in pairs cuts study time in half.
Frequently Asked Questions
What is the fastest way to learn Morse code using quizzes?
Start with Level 1 (ETAOIN) in Decode mode. Listen to the audio before looking at the visual signals. Once you consistently score 100%, progress to A–M, N–Z, and full words.
What is the difference between Decode and Encode mode?
Decode mode simulates receiving a transmission: you see or hear the Morse code and identify the letter or word. Encode mode simulates sending: you see the character and choose the correct dot-dash combination.
What are prosigns in Morse code?
Prosigns (procedural signals) are telegraph abbreviations sent without inter-letter spaces to manage communications — such as SOS (distress), CQ (calling all stations), and AR (end of message).
Can I test myself on Morse code numbers and punctuation?
Yes! Use the Numbers (0–9) tab to test all digits, each of which uses exactly 5 symbols. Use the Punctuation tab to practice essential symbols like periods, commas, and question marks.
