The history and invention of Morse code

Morse code was developed by Samuel Morse and Alfred Vail between 1836 and 1844, initially for telegraph communication. The first telegraph message — "What hath God wrought" — was sent by Morse from Washington D.C. to Baltimore on May 24, 1844. The code assigns each letter, digit and punctuation mark a unique sequence of short signals (dots) and long signals (dashes) in a ratio of 1:3. Frequently used letters get shorter codes (E = ".", T = "-"), while rare letters get longer ones (Q = "--.-"), making transmission efficient. The distress signal SOS ("... --- ...") was adopted internationally in 1908 specifically because it is easy to send under duress.

Is Morse code still used today?

Yes — more than you might expect. Amateur (ham) radio operators worldwide still use Morse (CW — Continuous Wave) and it remains the most noise-resistant form of radio communication at low power. The international maritime distress frequency still monitors for Morse. Aviation navigation beacons (VOR, NDB) transmit their identifier in Morse. People with severe motor disabilities use Morse code input systems for computer access. And it is used by military units for covert communication. Our translator features audio playback at 600 Hz — the standard amateur radio frequency — so you can hear your messages as they would be transmitted.
