C in Morse Code — −·−·
What is C in Morse Code?
The letter C in Morse code is dash-dot-dash-dot (− · − ·). Its alternating pattern of long and short signals creates a distinctive rhythm that experienced operators can easily recognize.
In International Morse Code, the letter C is encoded as −·−· — consisting of 2 dots and 2 dashes. The total transmission length is 11 time units. In the NATO phonetic alphabet, C is represented by the word "Charlie" to avoid miscommunication over radio.
How to Transmit C in Morse Code
To transmit the letter C (−·−·) in Morse code, follow these steps:
- Send a long signal (dash) — 3 time units then pause for 1 unit
- Send a short signal (dot) — 1 time unit then pause for 1 unit
- Send a long signal (dash) — 3 time units then pause for 1 unit
- Send a short signal (dot) — 1 time unit
At 20 WPM (words per minute), one time unit equals 60 milliseconds. So the letter C takes approximately 660ms to transmit at this speed.

Mnemonic: How to Remember C in Morse Code
C sounds like "dah-di-dah-dit" — think of it as a "CAN-you-CAN-it" rhythm with emphasis on the CAN parts (dashes).

Interesting Fact About C in Morse Code
The Morse code for C (− · − ·) is the same rhythm used in the opening of Beethoven's Fifth Symphony when played on a telegraph key — though the famous symphony motif actually corresponds to the letter V.
Letter C Frequency in English
The letter C appears in approximately 2.8% of English text, making it the #13 most common letter out of 26.
C has a moderate frequency in English. Its Morse code length of 4 elements represents a balance between code complexity and the letter's usage rate.

Complete Guide to C (−·−·) in Morse Code
The Morse code representation for the letter C is −·−·, which is vocalized as "dah-di-dah-dit". This encoding is part of the International Morse Code standard adopted in 1865 and still in use worldwide today.
When transmitting C by sound, the dots should be short, crisp signals and the dashes should last exactly three times the duration of a dot. Proper timing between elements (1 unit of silence) is crucial for the receiver to correctly decode the letter.
In practical use, the letter C can be transmitted using various methods: a telegraph key, a radio transmitter, a flashlight (short flash = dot, long flash = dash), a whistle, or even by tapping. The medium doesn't matter — only the relative timing between short and long signals.
For amateur radio operators using CW (Continuous Wave) mode, the letter C is one of the moderately common characters that appears regularly in general communication.
Frequently Asked Questions About C in Morse Code
What is the letter C in Morse code?
The letter C in Morse code is − · − · (dash dot dash dot), pronounced "dah-di-dah-dit". It alternates between long and short signals.
How do you remember C in Morse code?
The alternating dash-dot pattern (− · − ·) can be remembered as "Charlie-Charlie" or the rhythm "CAN-you-CAN-it" with the stressed syllables matching the dashes.
Is C difficult to learn in Morse code?
C is moderately challenging because its alternating pattern can be confused with F (· · − ·) or K (− · −). Practice listening to the rhythm rather than counting elements.
What is the NATO phonetic for the letter C?
The NATO phonetic alphabet word for C is "Charlie". It is universally used in radio communication to clearly identify the letter C.
