Morse code was invented by Samuel Morse in 1836 and uses combinations of dots (.) and dashes (-) to represent letters and numbers. It was widely used in short and long-distance communications, playing a critical role in maritime radio and military communications. It is still actively used today in amateur radio (ham radio) communities.
The international Morse code in use today is standardized by the ITU (International Telecommunication Union) and includes the A-Z alphabet, 0-9 digits, and various punctuation and special characters. A dot (dit) is a short signal, and a dash (dah) is three times the length of a dot. The gap between characters is three dots long, and the gap between words is seven dots long.
Morse code continues to be used in various fields today. In amateur radio, it is included as a licensing exam subject and remains highly valuable as an emergency communication method. It is also used as an assistive communication tool for people with hearing or motor disabilities. SOS (... --- ...) is an internationally recognized distress signal worldwide.
SOS is expressed as ... --- ... . S is three dots (...) and O is three dashes (---). It is the most famous Morse code pattern and the international distress signal, which can be transmitted via radio, light, sound, and various other media.
Skilled Morse code operators can send and receive at 25-40 words per minute (WPM). World record holders can exceed 60 WPM. Beginners usually start at 5-10 WPM and increase speed with practice.
Since standard Morse code is based on the Latin alphabet, Korean characters are first converted to their romanized pronunciation and then encoded into Morse code. For example, "안녕" is converted to "ANNYEONG" and then represented in Morse code. This converter handles the Korean-to-romanization conversion automatically.
It typically takes 1-2 weeks to learn the basic alphabet and numbers, and several months of consistent practice to reach a practical speed of 10-15 WPM. Learning by ear (audio) is the most effective method, and the sound playback feature in this converter can be very helpful.
Morse code is an analog communication method that conveys information through temporal signal patterns of dots and dashes. QR codes are two-dimensional barcodes storing digital data in black-and-white patterns. Morse code can be transmitted via sound, light, radio waves, and other media, while QR codes are recognized only visually.
