The History and Timing Rules of Morse Code
Developed in the 1830s by Samuel Morse and Alfred Vail for electric telegraphy, Morse code transmits text information as a series of on-off tones, lights, or clicks. In the standard International Morse Code format standardized by the International Telecommunication Union (ITU):
- The length of a dot (dit) is one unit.
- A dash (dah) is three units long.
- The space between parts of the same letter is one unit.
- The space between letters is three units.
- The space between words is seven units (represented as
/in text).
Frequently Asked Questions
Can this translator decode Morse code audio files?
This tool decodes text-based Morse characters into English and synthesizes audio playback. For audio file decoding, future updates will support microphone input.
What frequency is the CW audio beep?
The audio tone is synthesized at 550 Hz, which is the standard pitch favored by amateur radio operators to reduce ear fatigue.
