About Morse Code

Morse Code is a method of encoding text characters as standardized sequences of two different signal durations, called dots (·) and dashes (—). It was invented by Samuel Morse in the 1830s and served as the foundation for early telegraph communication.

Morse code is not only used for telegraphy but also widely applied in radio communications, maritime navigation, military operations, and other fields. Even in modern times, learning Morse code remains an interesting and practical skill.

History of Morse Code

  • 1837: Samuel Morse invents the Morse code
  • 1844: The first telegraph line opens, sending "What hath God wrought"
  • 1900s: Becomes the international standard for telegraph encoding
  • Present day: Still used in amateur radio, emergency communications, and more

Frequently Asked Questions

What is Morse code?

Morse code is a method of encoding text characters using sequences of dots (·) and dashes (—). Invented by Samuel Morse in the 1830s, it was the foundation of early telegraph communication.

How does Morse code work?

Morse code distinguishes characters by different signal lengths: dots (·) are short signals, dashes (—) are long signals. Each letter and number has its corresponding dot-dash combination. There are gaps between letters, and longer gaps between words.

Why do some characters appear as question marks?

Question marks indicate the character was not found in the Morse code mapping table. This could be due to unsupported Chinese characters, special symbols, or other unsupported characters. This is normal and does not affect the conversion of other characters.

How do I adjust the audio playback speed?

Use the WPM (Words Per Minute) slider in the audio control panel to adjust playback speed. Beginners are advised to start with a lower speed (e.g., 10-15 WPM) and gradually increase as proficiency improves.

Which character sets are supported?

This tool supports standard Latin letters (A-Z), numbers (0-9), common punctuation marks, and Chinese telegraph code (common characters). It also supports extended character sets for Russian, Greek, Japanese, and more.

What is Chinese telegraph code?

Chinese telegraph code is a method of converting Chinese characters into 4-digit numbers for telegraph communication. Each Chinese character corresponds to a unique 4-digit code. This tool includes telegraph code mappings for common Chinese characters.

How can I practice Morse code?

Use the practice mode to generate random practice questions and help you learn and memorize Morse code. We recommend practicing 10-15 minutes daily, gradually improving your recognition speed.
