How Morse Code Works
A dot lasts 1 unit; a dash lasts 3 units. Space between elements: 1 unit. Between letters: 3 units. Between words: 7 units. The most common English letter E = · (one dot), T = — (one dash). Rare letters like Q use 4 elements.
Binary Tree Memorization
Morse code forms a binary tree — left = dot, right = dash from the root. E and T at level 1, I/A and N/M at level 2. Navigate the tree to decode without looking up a chart — the method used by every licensed ham radio operator.
Phonetic Rhythms
Learn sounds, not symbols: C = “Co-ca-Co-la” (—·—·), F = “Did-I-make-it” (··—·), Q = “God save the Queen” (——·—).
Morse Code Numbers (0–9)
Numbers follow a perfect system: 1 = one dot + four dashes, adding a dot each time through 5, then removing dots and adding dashes through 9, ending with 0 = five dashes.
