Morse Code Alphabet

Morse Code Table

Morse code is a system that converts letters, numbers, and symbols into combinations of dots (.) and dashes (-). It was developed by Samuel Morse and his team in the 19th century. Morse code maps all English letters, numbers, and some special characters into dot and dash combinations. Below is the complete table:

• Click to Play: Each Morse code character has an audio button, which plays the corresponding sound of the character when clicked.
• One-Click Copy: You can copy any Morse code character for easy practice or other uses.

How to Quickly Memorize Morse Code

Learning Morse code might seem difficult at first, but with a few useful tricks, you'll find it much simpler. Here are some common techniques to help you memorize Morse code:

1. Association Technique

By associating the dots and dashes with everyday things, you'll make it easier to remember them:

• A (.-): Imagine the sound of an "apple" falling-first a light tap (.), then a longer sound when it hits the ground (-).
• B (-...): Think of a "bus horn"-a long beep followed by three quick short honks.
• D (-..): A "drumbeat"-one long beat followed by two quick ones.

This method makes remembering the code fun and memorable.

2. Visualization Technique

Transform the dots (.) and dashes (-) into a flashing light pattern:

• Dot (.): A quick flash, like a camera's shutter light.
• Dash (-): A longer flash, similar to a flashlight being turned on.

For example, HELLO (.... . .-.. .-.. ---) could be imagined as a light flashing rapidly in the rhythm of dots and dashes, creating a clear visual image.

3. Rhythm Technique

Use the rhythm of sounds to memorize the code:

• Dot (.) is like a single "beat" (short).
• Dash (-) is like a "long" sound, taking three beats.

During practice, you can clap your hands or tap a table to simulate the rhythm.

4. Group Learning

Break the letters into simple groups with patterns:

• Single dot or dash: E (.), T (-)
• Dot-dash combinations: A (.-), N (-.)
• Two dots or two dashes: I (..), M (--)
• Complex types: L (.-..), F (..-.)

Grouping makes memorization easier and more efficient.

Morse Code Timing Rules

Morse code transmission follows strict timing rules. Here are the standard conventions:

• Dot (.): Lasts for 1 time unit.
• Dash (-): Lasts for 3 time units.
• Character Spacing (within the same letter): 1 time unit between characters.
• Letter Spacing (between letters): 3 time units between letters.
• Word Spacing: 7 time units between words.

Example Explained

To send "HI":

• H (....): The dots last 1 time unit each, with 1 time unit between each dot, giving a total of 7 time units (4 dots + 3 intervals).
• I (..): The dots last 1 time unit each, with 1 time unit between them, for a total of 3 time units (2 dots + 1 interval).

Complete transmission: The total time to send "HI" is 13 time units (H's 7 time units + letter spacing 3 time units + I's 3 time units).

Example 2: "HELLO" (.... . .-.. .-.. ---)

• H (....): 7 time units
• E (.): 1 time unit
• L (.-..): 6 time units (4 symbols) + 3 intervals = 9 time units
• O (---): 9 time units (3 dashes) + 2 intervals = 11 time units
• Letter Spacing: 4 × 3 time units = 12 time units

Total time: 7 + 1 + 9 × 2 + 11 + 12 = 49 time units

Example 3: "SOS" (... --- ...)

• S (...): 5 time units
• O (---): 11 time units
• Second S (...): 5 time units
• Letter Spacing: 2 × 3 time units = 6 time units

Total time: 5 + 11 + 5 + 6 = 27 time units
