C in Morse Code: Alternating Dash Dot

What Is C in Morse Code?

The letter C in Morse code is -.-.. It is sent as dash dot dash dot, or dah dit dah dit. Unlike letters that group all dots or all dashes together, C has an alternating rhythm, which makes it one of the more musical letters in the Morse alphabet.

Why C Has a Distinct Sound

C is useful for ear training because it forces you to hear the order of the elements, not just count them. A beginner might remember that C has two dashes and two dots, but that is not enough. The exact sequence is what matters: dash, dot, dash, dot. If the final dot is dropped, the sound becomes K, -.-. If the last part is changed, it may drift toward Y, -.--.

C, K, and CQ

C is also interesting because it appears at the start of the well-known radio call “CQ,” used to invite any station to respond. CQ is sent as C followed by Q, so the C portion is -.-.. For a single-letter lookup page, the key point is that C should still be practiced as its own complete character with the normal character gap after it. It is not a prosign by itself.

Practical Uses for C

The letter C is common in initials, names, brand abbreviations, school exercises, and puzzle clues. Its alternating shape looks good in graphic design because it creates a clear long-short-long-short pattern. That makes -.-. useful for bracelets, tattoos, stickers, keychains, or hidden codes inside a poster or game interface.

How to Practice C

Practice C by pairing it with K and Y. Send C as dah dit dah dit, K as dah dit dah, and Y as dah dit dah dah. This comparison gives the ear a reason to notice the ending. Once you can hear whether the character stops after K or continues into C, decoding names and callsigns becomes much easier.
