Spanish Morse Code

The 26 + 4 layout

Spanish writes its language using the standard 26 Latin letters plus the eñe (Ñ), so the bulk of Spanish morse is identical to international morse. Every Latin letter A–Z keeps its standard dot-dash pattern. The extra four letters historically used in Spanish typography were assigned their own morse patterns and remain in use in formal training materials and amateur radio.

Note that in 1994 the Real Academia Española (RAE) officially removed CH and LL as separate dictionary letters and merged them into C and L alphabetisation. The morse encodings did not change — CH and LL still have dedicated dot-dash patterns — but in practice modern Spanish CW operators almost never use them. They send each letter separately: chico goes out as C-H-I-C-O, not as the CH digraph.

Spanish-only morse patterns

The eñe is the only one in regular use

Of the four Spanish-only morse characters, only the eñe (Ñ, dah-dah-dit-dah-dah, --.--) is in regular CW use today. Spanish proper nouns, surnames, and common words like año (year), niño (child), señor (mister), and pequeño (small) contain Ñ, and CW operators send it as the dedicated five- element pattern.

The pattern --.-- is shared with Russian morse's hard sign (Ъ). The two systems can coexist because each language only uses one of the two: a Spanish operator never types Ъ; a Russian operator never types Ñ. Within the Spanish context, dah-dah-dit-dah-dah means eñe.

Accented vowels (á, é, í, ó, ú)

Spanish uses acute accents over vowels (á, é, í, ó, ú) to mark stress, and the diaeresis (ü) in some words like vergüenza. None of these have dedicated morse patterns in the international standard. CW operators send the unaccented vowel and rely on the reader to recognise the word in context.

So café goes out as C-A-F-E. Más goes out as M-A-S. The acute accent is invisible in the morse stream. This is a small efficiency loss for written Spanish (some words are technically ambiguous without their accents) but the loss is rarely a problem in conversational CW where context disambiguates.

Spanish in amateur radio today

Spanish-speaking amateur radio operators are active worldwide. The major callsign prefixes are:

• EA, EB, EC, ED, EE, EF, EG, EH — Spain (including the Balearic and Canary Islands which have sub-prefixes EA6, EA8, etc.).
• LU — Argentina.
• CE — Chile.
• XE — Mexico.
• CO — Cuba.
• HK — Colombia. OA — Peru. YV — Venezuela. HC — Ecuador. CX — Uruguay.

A Spanish-language CW QSO follows the same structure as any international QSO: callsign exchange in standard morse, signal report, name (nombre), location (QTH), rig description, and signoff. Spanish operators frequently use Spanish-language Q-code equivalents in informal contacts: QRZ remains universal (“who is calling me”), and Spanish abbreviations like GRX (gracias, thanks) sometimes appear in casual exchanges.
