The Legacy of Morse Code

Invented by Samuel Morse in the 1830s, Morse code revolutionized long-distance communication. For over a century, it was the primary method of sending messages across telegraph lines and later via radio. Today, it remains in use by amateur radio operators and in emergency signaling. Our free translator makes it easy to experiment with this historical code.
