Yes in Morse Code

Yes and No in Morse Code — Radio Brevity

"Yes" and "No" in Morse code are rarely sent as full words in actual radio communication. Experienced operators have a shorthand system of Q-codes and single-letter abbreviations that communicates the same meaning in far fewer elements.

For confirmation, operators use C (·-·-·) or the signal R (·-) meaning "received, all correct." For denial or negative, operators use N (-·) or the signal NK (meaning "not received"). The Q-code QSL means "acknowledged" — confirming receipt and understanding.

However, in plain-text Morse (like a radiogram or formal message), YES and NO are perfectly valid. And for anyone learning Morse code, three-letter words like YES and NO make great practice because they cover a variety of different code lengths: Y is one of the longer codes (four elements), E is the shortest (one element), S is three elements — a range that exercises your ear for different rhythms.

In the context of escape rooms, hidden messages, and novelty use, YES and NO are often encoded and decoded as a puzzle element. The translator below handles both words instantly.
