Morse Code Timing Rules

Understanding the timing is essential for proper Morse code transmission:

Dot (dit): 1 unit of time
Dash (dah): 3 units of time
Space between elements: 1 unit of time
Space between letters: 3 units of time
Space between words: 7 units of time

History of Morse Code

Morse code was developed by Samuel Morse and Alfred Vail in the 1830s and 1840s. The first official message sent was "What hath God wrought?" transmitted from Washington D.C. to Baltimore on May 24, 1844.

The International Morse Code (also known as Continental Morse Code) standardized the system globally, and it remains in use today in aviation, amateur radio, and emergency communications.

Common Uses Today

Amateur (ham) radio operators — CW (Continuous Wave) operation
Aviation — VOR/NDB beacons still broadcast in Morse
Emergency signaling — SOS (... --- ...) is universally recognized
Military communications
Escape rooms and puzzle games
