How does Korean Morse code work?

Korean Morse, related to the SKATS system, assigns a dot-dash sequence to each Hangul jamo — the individual consonants and vowels. A syllable block is first decomposed into its jamo, then each jamo is sent in turn.

How are syllable blocks handled?

Modern Hangul syllables are composed from a lead consonant, a vowel, and an optional final consonant. The encoder splits each block back into these jamo using Unicode rules, then encodes each jamo.

Does Korean Morse reuse international Morse symbols?

It uses the same dots and dashes but maps them to Korean jamo rather than Latin letters, so the meaning of a given sequence differs from international Morse and the two must not be mixed.

What about double consonants and compound vowels?

Double consonants such as ㄲ and compound vowels such as ㅘ are themselves jamo with their own positions. This encoder decomposes them to their base jamo so each component is sent in sequence.

Is my text uploaded anywhere?

No. Decomposition and encoding run entirely in your browser and nothing is sent to any server.

Korean Morse Code Encoder

Korean Morse code adapts the dot-dash alphabet to Hangul by assigning a sequence to each jamo — the individual consonants and vowels that make up a syllable. Because written Korean stacks jamo into square syllable blocks, the encoder first decomposes each block back into its parts, then sends each jamo in order. It all runs in your browser.

How it works

Every modern Hangul syllable in Unicode is built from a lead consonant (초성), a vowel (중성), and an optional final consonant (받침/종성). Given a syllable code point, the position of each component can be recovered arithmetically:

S = code - 0xAC00
final  = S % 28
vowel  = (S / 28) % 21
lead   = S / (28 * 21)

Each recovered jamo is then mapped to its Korean Morse dot-dash sequence. Within a syllable the jamo codes are joined by short gaps, and a larger gap separates one syllable from the next, mirroring how letters and characters are spaced in Morse.

Tips and example

Take the syllable 간: it decomposes to ㄱ (lead), ㅏ (vowel), ㄴ (final). Each of those three jamo has its own Morse sequence, sent in that order to transmit the syllable.

Compound jamo such as the vowel ㅘ or the double consonant ㄲ are decomposed to their base components so every piece is encoded. As with Wabun, Korean Morse reuses the familiar dots and dashes but assigns them new meanings — operators must agree on the mode before sending. Use this tool for study and amateur practice.
