Morse code once played a major role in long-distance telegraph communication. Modern voice, digital and satellite systems have replaced much of that work. However, Morse code has not disappeared: it continues to be used in certain radio contexts and is still practised by hobbyists and learners.
Amateur radio
Amateur-radio operators use Morse code, usually called CW (continuous wave) in radio practice. The American Radio Relay League (ARRL) publishes code-practice material and regular W1AW code transmissions at a range of speeds. Those resources show that Morse remains an active skill within amateur radio rather than only a historical subject.
Radio and international standards
The International Telecommunication Union maintains Recommendation ITU-R M.1677-1 for International Morse code. The ITU notes that Morse continues to be used mainly in the amateur and amateur-satellite services, and to a diminishing extent in other radio services. That is a more precise description than saying Morse is either universally used or completely obsolete. The Morse Orbit alphabet follows this Recommendation.
Learning, hobbies and demonstrations
People also learn Morse code for personal interest, radio training, classroom demonstrations, puzzles and communication history. Its simple signal patterns make it a clear way to understand timing, encoding and the difference between a signal and the message it carries.

| RADIO | .-. .- -.. .. --- | |

Does Morse code replace modern emergency systems?
No. A web translator, phone flashlight or hobby radio demonstration should not be treated as a substitute for official emergency channels or certified distress equipment. In an emergency, use the local emergency service and equipment appropriate to the situation. The SOS guide explains where the SOS signal still appears in the international rules.

Do amateur-radio operators still use Morse code?
Yes. Amateur-radio organisations such as the ARRL continue to publish Morse practice material and support operators who use it.
Is Morse code required for every amateur-radio licence?
Licensing rules vary by country and have changed over time. Check your national regulator's current rules rather than relying on historical requirements.
Is Morse code obsolete?
It is no longer a mainstream everyday communication method, but it remains active in some specialist radio and learning contexts.
