Morse code accented letters
Only one accented letter, É, is in the International Morse code standard. The rest are national extensions: codes that operators who share a language use with each other. Several of them share one code, so the letter depends on the language.
Accented letters in use
| Letter | Morse code | ITU | Play |
|---|---|---|---|
| É | dot dot dash dot dot | Yes | |
| Ä | dot dash dot dash | No | |
| Ö | dash dash dash dot | No | |
| Ü | dot dot dash dash | No | |
| Å | dot dash dash dot dash | No | |
| Ñ | dash dash dot dash dash | No | |
| Ch | dash dash dash dash | No | |

Letters that share a code
National tables reuse codes, so the same signal means different letters in different languages. Read it in the language of the message.
| Morse code | Letters |
|---|---|
| .-.- | Ä, Æ, Ą |
| ---. | Ö, Ø, Ó |
| ..-- | Ü, Ŭ |
| .--.- | Å, À |
| --.-- | Ñ, Ń |
| ---- | Ch, Š, Ĥ |
| -.-.. | Ç, Ć, Ĉ |
One extension even collides with a standard signal: the Esperanto letter Ŝ uses ...-., which the ITU defines as “understood”.
What to send instead
If the other station may not know the extension, spell the letter with plain characters. Every operator can copy these.
By language
- Norwegian and Danish
- Å
