Morse Code Accented Letters

Accented letters in Morse code used in European languages. These are formal extensions of International Morse. Click any letter to hear it.

European Morse standard

European languages use accented characters as part of normal writing. Morse code includes official patterns for these letters so operators can send text accurately in French, German, Spanish, Portuguese, and Scandinavian languages without spelling out the accents. The codes are standardised by the International Telecommunication Union, the same body that defines all International Morse code.

Common accented letters

The most frequently used are À and Á (French), Ä and Ö (German and Swedish), É and È (French), Ñ (Spanish), and Ü (German). Each has its own code pattern that extends the base-letter system. An operator would use these codes when sending text in the appropriate language. For instance, French operators regularly send messages containing É, which appears frequently in French text. Similarly, German and Swedish operators use Ä and Ö in normal traffic.

Pattern structure

Accented letters are often related to their base letters in the Morse code pattern, though not always directly. À (grave A) has the pattern .--.- while A is .-, showing a modification. This relationship helps operators learn the accented variants more easily. However, some accents introduce entirely new patterns that must be memorised separately. The logic behind the pattern assignments prioritises clarity and distinctiveness over a systematic relationship.

Spelling out vs. codes

In formal radio traffic, operators use the accented-letter codes when available. In informal Morse or when equipment does not support the full extended set, operators may spell out the accent word: A WITH ACUTE for Á, A WITH UMLAUT for Ä. Both approaches are acceptable depending on context. Modern digital Morse systems typically support the full extended character set, making the accented codes more common in contemporary amateur radio practice than in the past.
