Morse Code Interpreter: from signals to meaning
Interpreting Morse is decoding plus meaning
Decoding turns ... --- ... into letters; interpreting tells you someone is in distress. Real Morse traffic is dense with abbreviations, Q-codes, and procedural signals that translate into letters but not into sense unless you know the conventions. The interpreter above decodes anything you paste instantly, both directions, with playback and live highlighting, and this page adds the layer no character chart covers: what the codes operators actually send really mean, and how to build the by-ear copying skill that turns heard rhythms into understood messages.
Interpreting Morse abbreviations and Q-codes
A century of operators compressing common phrases produced a shared shorthand: two or three letters that carry a whole sentence. These are the ones you will hear most, with what they actually mean. Click any row to hear it as Morse.

| 73 | --... ...-- | Best regards: the standard friendly sign-off | ▶ play |
| 88 | ---.. ---.. | Love and kisses: the affectionate sign-off | ▶ play |
| QTH | --.- - .... | My location is (or, with a question mark, what is your location?) | ▶ play |
| QRZ | --.- .-. --.. | Who is calling me? | ▶ play |
| QSL | --.- ... .-.. | I confirm receipt (also the name of the confirmation postcards hams exchange) | ▶ play |
| QRS | --.- .-. ... | Send more slowly: the most useful code a learner can know | ▶ play |
| ES | . ... | And: borrowed from old American Morse | ▶ play |
| TU | - ..- | Thank you: often heard at the end of contest exchanges | ▶ play |
Prosigns such as SOS, AR, and SK are a separate category, sent as single run-together patterns; the prosign table on the main page plays each one correctly.
How to interpret Morse by ear
Operators call it copying, and it is the skill this page is built to practise. The workflow that works:
Transcribe what you hear
Listen to the Morse, at reduced speed if you can get it, and write the rhythms as dots and dashes: . for every short tone, - for every long one, a space when a letter ends, a slash at the longer word pauses.
Paste and decode
Paste your transcription into the interpreter above. Correct patterns become text instantly; anything that matches no real character is flagged, which is exactly where your transcription slipped, usually a missed gap or a dah heard as a dit.
Compare against playback
Press Play and follow the live highlighting. Hearing your transcription back, element by element, against your memory of the original is the fastest correction loop there is, and over time the decode step happens in your head before you reach the keyboard.
