X in Morse Code — −··−
What is X in Morse Code?
The letter X in Morse code is dash-dot-dot-dash (− · · −). Like P, it is a palindrome — reading the same forwards and backwards — giving it a distinctive symmetrical sound.
In International Morse Code, the letter X is encoded as −··− — consisting of 2 dots and 2 dashes. The total transmission length is 11 time units. In the NATO phonetic alphabet, X is represented by the word "X-ray" to avoid miscommunication over radio.
How to Transmit X in Morse Code
To transmit the letter X (−··−) 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 short signal (dot) — 1 time unit then pause for 1 unit
- Send a long signal (dash) — 3 time units
At 20 WPM (words per minute), one time unit equals 60 milliseconds. So the letter X takes approximately 660ms to transmit at this speed.

Mnemonic: How to Remember X in Morse Code
X marks the spot with symmetry: dah-di-di-dah. Strong ends with a soft middle — like the X shape itself which is symmetric.

Here are common words containing the letter X, with their complete Morse code breakdown:
Interesting Fact About X in Morse Code
X (− · · −) is one of only a few palindromic Morse code characters. Its symmetrical pattern makes it one of the more elegant codes. In radio communication, X is rarely used in regular text but appears in call signs and abbreviations.
Letter X Frequency in English
The letter X appears in approximately 0.15% of English text, making it the #24 most common letter out of 26.
X is relatively rare in English text. Despite its lower frequency, knowing its Morse code is important for complete alphabet mastery and for decoding words that contain it.

Complete Guide to X (−··−) in Morse Code
The Morse code representation for the letter X is −··−, which is vocalized as "dah-di-di-dah". This encoding is part of the International Morse Code standard adopted in 1865 and still in use worldwide today.
When transmitting X 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 X 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 X is one of the less common characters, but still essential for complete message transmission and proper spelling.
Frequently Asked Questions About X in Morse Code
What is the letter X in Morse code?
The letter X in Morse code is − · · − (dash dot dot dash), pronounced "dah-di-di-dah". It has a symmetric pattern with dashes on the outside and dots in the middle.
How do you remember X in Morse code?
X is a palindrome — it reads the same backward. Think of X as "eXtreme" — strong on both ends (dashes) with quick beats in the middle (dots).
Is X commonly used in Morse code?
X is rare in regular English text (0.15% frequency) but appears in call signs, abbreviations like "XMIT" (transmit), and in scientific/technical contexts like X-ray.
What is the NATO phonetic for the letter X?
The NATO phonetic alphabet word for X is "X-ray". It is used in communications to clearly identify the letter X.
