How to Read Morse Code

Reading Morse is less like decoding a cipher and more like catching a rhythm. You are listening (or looking) for short beats, long beats, and the silence between them.

The three silences

Inside a letter, the gap is one unit — just enough to separate a dot from a dash. After a letter, wait three units. After a word, wait seven. On this site those last two gaps are a space and a slash, so ... --- ... is SOS and not a single nine-signal blob.

If a message looks wrong, spacing is usually the fault. .... is H. .. .. is I I. Same four dots, different gaps.

An easy Morse code alphabet to start with

Do not begin with Q. Start with the short end of the alphabet chart:

• E . and T -
• I .. and M --
• S ... and O ---

Those six letters give you SOS, and a surprising number of tiny English words. Add A (.-) and N (-.) next — they are mirrors of each other. Numbers are a separate pattern: every digit is five signals. See the numbers chart once letters feel steady.

Listen instead of counting

Counting dots works at a desk. On the air, or even at 20 WPM in a browser, it falls apart. Operators learn the sound of a whole letter: di-dah is A, dah-di-dah-dit is C. Play a word you already know on the audio translator, then raise the speed until you stop counting.

For the underlying timing math — PARIS, WPM, unit length — the timing page is the short version. For what Morse is in the first place, start with what is Morse code.
