Morse Code Flashcards: A–Z and 0–9 in Both Directions

Learn International Morse Code with 72 two-way visual-recall cards covering every letter A–Z and digit 0–9 from character to pattern and pattern to character.

Recommendation ITU-R M.1677-1 lists Morse signals for the 26 letters A–Z, the accented letter é, and the ten figures 0–9. This deck deliberately uses the A–Z and 0–9 subset, turning those 36 character mappings into 72 visual-recall cards: each character asks for its dot-and-dash pattern, and each pattern asks for its character.

The cards use one deterministic mixed sequence instead of alphabetical or numeric runs. Every reverse pair is separated by at least 32 cards, and one-step-confusable patterns are kept at least three positions apart, so nearby prompts don’t hand over the next answer.

Scope stays narrow: no punctuation, accented characters, prosigns, timing rules, words, callsigns, mnemonics, audio, cut numbers, or sending/key technique. The deck trains visual recall of individual character mappings. It doesn’t replace listening to real CW (continuous-wave Morse) or practicing transmission.
