Morse Code Letter

B in Morse Code — −···

−···
Pronounced: dah-di-di-dit
NATO Phonetic: Bravo

What is B in Morse Code?

The letter B in Morse code is a dash followed by three dots (− · · ·). It is the mirror image of V (· · · −), which is a common source of confusion for beginners.

In International Morse Code, the letter B is encoded as −··· — consisting of 3 dots and 1 dash. The total transmission length is 9 time units. In the NATO phonetic alphabet, B is represented by the word "Bravo" to avoid miscommunication over radio.

How to Transmit B in Morse Code

To transmit the letter B (−···) in Morse code, follow these steps:

  1. Send a long signal (dash) — 3 time units then pause for 1 unit
  2. Send a short signal (dot) — 1 time unit then pause for 1 unit
  3. Send a short signal (dot) — 1 time unit then pause for 1 unit
  4. Send a short signal (dot) — 1 time unit

At 20 WPM (words per minute), one time unit equals 60 milliseconds. So the letter B takes approximately 540ms to transmit at this speed.

Visual Signal Pattern

■ Short = Dot (1 unit) ■■■ Long = Dash (3 units) Gap = 1 unit silence

Mnemonic: How to Remember B in Morse Code

Think of the word "BOOT" — it starts heavy (dah) and then has three quick light steps (di-di-dit). The dash leads like the toe of a boot.

B = −··· = "dah-di-di-dit"

Interesting Fact About B in Morse Code

B and V are exact mirror images in Morse code. B is − · · · while V is · · · −. This pairing is one of the most commonly confused in Morse code learning.

Letter B Frequency in English

The letter B appears in approximately 1.5% of English text, making it the #20 most common letter out of 26.

B 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 B (−···) in Morse Code

The Morse code representation for the letter B is −···, which is vocalized as "dah-di-di-dit". This encoding is part of the International Morse Code standard adopted in 1865 and still in use worldwide today.

When transmitting B by sound, the dots should be short, crisp signals and the dash 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 B 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 B is one of the less common characters, but still essential for complete message transmission and proper spelling.

Frequently Asked Questions About B in Morse Code

What is the letter B in Morse code?

The letter B in Morse code is − · · · (dash dot dot dot), pronounced "dah-di-di-dit". It has one long signal followed by three short signals.

How do you tell B and V apart in Morse code?

B (− · · ·) starts with a dash and ends with dots. V (· · · −) starts with dots and ends with a dash. They are exact mirrors. Focus on whether the dash comes first (B) or last (V).

How do you remember B in Morse code?

Remember "B begins with a bang" — the dash (long signal) comes first, followed by three quick dots. Alternatively, the rhythm sounds like "BOOT-to-the-head" with emphasis on the first beat.

What is the NATO phonetic for the letter B?

The NATO phonetic alphabet word for B is "Bravo". It is used in military and aviation radio communication to clearly identify the letter B.
