Origins Of Morse Code and How It Functions?

Way back in 1836, Samuel F. B. Morse, along with Joseph Henry and Alfred Vail, created an electrical telegraph system. Before telephones were introduced, they could transmit messages over long distances by using pulsations of electricity to signal the device to make marks on a moving paper tape.

A code was essential to help decipher the marks on the paper tape into readable text messages. Morse designed the first interpretation of this code. His interpretation includes only numbers. Vail soon extended it to include letters and a few unusual characters, such as punctuation spots.

The code — comprehended as Morse code — appointed each number, letter, or special character a distinctive series of short and long signals called “dots” and “dashes.”

Morse Code Communication

In Morse code communication the quick dot signal is the basic time measurement. A prolonged dash signal is equal to three dots. Every dot or dash is followed by a short silence that’s equal to a dot.

If you think how they determined which combination of signals was assigned to each letter, they studied how frequently each letter in the English language was utilized.

The most utilized letters are given shorter sequences of dots and dashes. For example, the most typically used letter in the English language — E — is illustrated by a single dot.

Telegraph Machines

The original telegraph machines created a clicking noise as they observed the moving paper tape. The paper tape ultimately became unneeded. Telegraph operators soon learned that they could translate the clicks literally into dots and dashes.

Later, operators were trained in Morse code by examining it as a language that was heard rather than read from a page. Although Morse initially directed to code signals as dots and dashes, operators started to vocalize dots as “dits” and dashes as “dahs” to mimic the sound of Morse code receivers.

Today, it’s conceivable to transmit messages in Morse code in any way that dots and dashes can be transmitted. This contains sounds and lights, as well as printed dots and dashes.

Morse code was required for transmission during World War II. It was also operated as an international standard for communication at sea. In 1999 when it was replaced by the Global Maritime Distress Safety System. The substitute system takes benefit of advances in technology, such as satellite transmission.

Today, Morse code stays popular with amateur radio operators roughly the world. It is also typically used for emergency signals. It can be sent in a variety of ways with spontaneous devices that can be switched effortlessly on and off, such as flashlights.

International Morse code

The international Morse code misery signal ( · · · — — — · · · ) was first used by the German government in 1905 and became the definitive anguish signal almost the world just a few years later. The repeated practice of three dots observed by three dashes was easy to recognize and desired for its plainness.

In Morse code, three dots form the letter S and three dashes form the letter O, so SOS evolved a shorthand way to determine the sequence of the code. Later, SOS was associated with particular phrases, such as “save our ship” and “save our souls.”

These were just easy ways to recognize SOS, though. The letters themselves have no such intrinsic purpose.

The Rules Of The Morse Code

The rules of the Morse code areas were observed. Each “dot” functions as the basis of time for the code. One dash is equivalent to the length of three dots. After each consistency, there is a silence that is equal to the length of one dot. This relative timing allows for Morse code to be easily sped up and slowed down all while keeping the same pace.

Try It Out

Willing to decode some dits and dahs? We’ve used Morse code to encode a special directive for all our Wonder Friends. 

Print out a Morse code key and use it to translate the special message. Note: The / is used to divide the terms of the message.

When you’re done constructing your special message. Operate your key to encode it using Morse code. Give your directive and the key to someone else and challenge him or her to decode it!

If you enjoy conveying with your friends and family using Morse code, try this online Morse Code Translator to encode and decode even longer messages.


Understanding Morse code completes for a pretty interesting party trick, and hey, you never know when you’ll be watching TV and realize there’s a person on it sending a secret message to you. Maybe you’ll be the only one that understands and you can be a hero. All this because you decided to learn Morse code.
