W in Morse Code — ·−−
What is W in Morse Code?
The letter W in Morse code is dot-dash-dash (· − −). It builds from a single dot to two dashes, creating a crescendo pattern. W is relatively common in English as the start of many question words.
In International Morse Code, the letter W is encoded as ·−− — consisting of 1 dot and 2 dashes. The total transmission length is 9 time units. In the NATO phonetic alphabet, W is represented by the word "Whiskey" to avoid miscommunication over radio.
How to Transmit W in Morse Code
To transmit the letter W (·−−) in Morse code, follow these steps:
- 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 long signal (dash) — 3 time units
At 20 WPM (words per minute), one time unit equals 60 milliseconds. So the letter W takes approximately 540ms to transmit at this speed.

Mnemonic: How to Remember W in Morse Code
W "Widens" — starts narrow (dot) then gets WIDE (dah-dah). Di-dah-dah sounds like it is opening up, expanding, just like the letter W gets wider.
Example Words with W in Morse Code
Here are common words containing the letter W, with their complete Morse code breakdown:
Interesting Fact About W in Morse Code
W (· − −) was not in the original American Morse Code because it could be confused with other characters. It was added when International Morse Code was standardized, using the ascending dot-dash-dash pattern.
Letter W Frequency in English
The letter W appears in approximately 2.4% of English text, making it the #15 most common letter out of 26.
W has a moderate frequency in English. Its Morse code length of 3 elements represents a balance between code complexity and the letter's usage rate.

Complete Guide to W (·−−) in Morse Code
The Morse code representation for the letter W is ·−−, which is vocalized as "di-dah-dah". This encoding is part of the International Morse Code standard adopted in 1865 and still in use worldwide today.
When transmitting W by sound, the dot should be short, crisp signal 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 W 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 W is one of the moderately common characters that appears regularly in general communication.
Frequently Asked Questions About W in Morse Code
What is the letter W in Morse code?
The letter W in Morse code is · − − (dot dash dash), pronounced "di-dah-dah". It starts with one short signal and ends with two long signals.
How do you remember W in Morse code?
W "Widens" or "opens up" — starting with a quick dot then expanding into two long dashes. The pattern builds from short to long, like the letter W spreading out.
What letters are similar to W in Morse code?
W (· − −) is the reverse of G (− − ·). J (· − − −) is W plus one more dash. A (· −) is W minus the last dash.
What is the NATO phonetic for the letter W?
The NATO phonetic alphabet word for W is "Whiskey". It is used in all international radio communications to identify the letter W.
