Morse Code Decoder (Morse Code to Text)

Side Note — the art of decoding by ear

Morse code was never really meant to be read as dots and dashes on paper. It was designed to be heard: a rhythm of short and long tones tapped out on a telegraph key, decoded instantly by a trained ear rather than looked up letter by letter in a table. Skilled telegraph operators reportedly learned to recognize entire words and common phrases as a single "sound pattern," much the way a fluent listener of a foreign language stops translating word by word and starts understanding whole phrases at once.

Because of this, historical training for telegraph and radio operators spent far more time on listening drills than on memorizing the code chart itself. Maritime and aviation radio licensing in many countries once required a practical sending-and-receiving exam as a core part of certification.

Even today, Morse code (referred to as "CW," for continuous wave, in radio circles) remains a recognized operating mode tied to advanced amateur radio licenses in a number of countries. Beyond its practical advantage of carrying over long distances with very little power and minimal equipment, there's something almost ceremonial about the fact that operators are still using a code system that has barely changed in over a century.
