Morse Code - What Is Morse code used for?

Morse coder

A way for communicating telegraphic information with the help of standardized series of short and long segments is called as Morse code. To represent the letters, numerals, punctuation, and special qualities of a message. 

The short and long segments can be developed by sounds, marks, or pulses, in on-off keying and are typically known as "dots" and "dashes" or "dits" and "dahs". If you require a list of the alphabet in Morse code please click on the image to the left. 

International Morse code contains six elements:

  • short mark, dot or 'dit' (·)

  • longer mark, dash, or 'dah' (-)

  • intra-character intermission (between the dots and dash within a character)

  • short gap (between letters)

  • medium gap (between words)

  • long gap (between sentences — nearly seven units of time)


These six factors perform as the foundation for the International Morse code and therefore can be devoted to the use of Morse code globally.


Morse code can be sent in several ways: initially as electrical pulses along a telegraph wire, but also as an audio tone, as a radio signal with quick and elongated pulses or tones, or as an automated or visual signal (e.g. a flashing light) operating devices like an Aldis lamp or a heliograph. 


Morse code is transferred employing just two states — on and off — so it was an earlier form of a digital code. However, it is technically not binary, as the uncertainty lengths are needed to decode the information.

The History of Morse Code-

Constructed for Samuel F. B. Morse's electric telegraph in the early 1840s, Morse code was also considerably used for early radio communication commencing in the 1890s.

For the first half of the twentieth century, the majority of high-speed international transmission was functioned in Morse code, using telegraph lines, undersea cables, and radio circuits. 

However, the uneven length of the Morse characters made it difficult to adjust to automatic circuits, so for the most electronic transmission, it has been replaced by more machinable formats, such as Baudot code and ASCII.

How is Morse Code Used Today?

The most prevalent current use of Morse code is by amateur radio operators. Although no longer essential for Amateur licensing in most countries, it also persists to be used for specialized purposes, including identification of navigational radio beacon and land mobile transmitters, plus some military contact, including flashing-light semaphore communications between ships in some naval assistance. 

Morse code is the only digital modulation mode created to be easily read by humans without a computer. Making it appropriate for sending automated digital data in voice channels, as well as making it ideal for emergency signaling. Such as by way of improvised energy sources that can be easy "key" such as by delivering and removing electric power (e.g. by switching a breaker on and off).


Morse and Vail's technology was widely embraced, not only in the United States but worldwide, and is enhanced as the insulation of the wires is enhanced. The man who invented this insulating technology, which fostered the transmission of clearer, stronger signals, was Ezra Cornell, founder of the New York university that bears his name. 

Thomas Alva Edison, one of the great inventors of the time, contributed to the Quadruplex system. This approach allowed multiple communications at once down the same line.

As the rage of telegraphs grew, more lines and stations were needed. Western Union was the first to lay a transcontinental telegraph line, in 1861. This extended up new markets and ways for people to transmit.

Early Forms of Long-Distance Communication

Ancient civilizations not only used smoke signals to send messages, but they also used sound to express themselves. However, smoke signals can only be used if the weather allowed, and the usage of sound could be restrained by nature. 

Egyptians, Greeks, and other civilizations managed forms of hieroglyphics and written words for transmission. But this was not a workable explanation when you needed to convey in a hurry and the receiver was a long-distance away.


The creation of the telegraph conveyed us into the age of nearly instant transmission. Today, wireless communication technologies have made phone lines and cables practically obsolete, but these are technological breakthroughs that even the creators of the telegraph could not have foreseen.


The benefit of the telegraph line as communication has fallen silent, but we owe our modern world of contacts to it and the inventor of Morse code, Samuel Morse.


For languages not written with the Latin alphabet, other versions of the Morse Code are utilized. There are interpretations of Morse Code for the Greek, Cyrillic, Arabic, and Hebrew alphabets, and for Japanese, a performance understood as Wabun Code, which maps kana syllables to precise codes, is utilized. 


The Chinese telegraph code is used to map Chinese characters to four-digit codes and then those digits are sent using definitive Morse code. Korean Morse code utilizes the SKATS (Standard Korean Alphabet Transliteration System) mapping, originally designed to allow Korean to be classified on western typewriters.


If you'd like to translate or decipher Morse code and if you do not know how to read it, you can use an online Morse code translator. With the Morse Decoder, you can decode Morse code and read English text easily.


Morse Code Translator is a translator that lets anyone translate text to Morse code and decode Morse code to text easily. With the online Morse code translator, anyone can convert any plain text in English or another language to Morse code and vice versa.
