Morse Code: The Original Confidential Communication Method

Morse code is a communication technique through which content characters, such as letters, numbers, and punctuation marks, are encoded into signals. Dots and dashes are the two distinct signal elements used in Morse code. Dots are referred to as “dits” in the official Morse language, and dashes are formally referred to as “dahs.” If you are not familiar with it, you might need to use an online tool to translate morse code

Morse code can be read using a variety of human senses, especially hearing and vision. People who understand the Morse code can interpret signals sent to them differently. Interestingly, morse codes are understandable to only those knowledgeable about them. 

Let’s discuss everything about Morse Code, which is a useful tool for confidential communication.

The Value and Background of Morse Code

In 1832, telegraphist Samuel Morse developed the first electric telegraph. The first communication to be transmitted using Morse code was a long-distance transmission from Washington, D.C., to Baltimore. People used to read printed text or send secret communications using smoke signals, beats, and semaphore devices. For the first time in human history, sophisticated thoughts could practically be transmitted over distant locations instantly. Powerful lights and Morse Code allowed for long-distance marine communication on long voyages. 

Morse Code was vital to communication in World War II because it dramatically accelerated the process. Communication with headquarters and the exchange of vital information between military ships were possible. Morse Code was also employed by fighter planes to convey information to the head office regarding the locations of enemy aircraft, camps, and soldiers.

SOS as a Signal of Emergency

Since 1906, the term “SOS” has been used to refer to an emergency call. The Morse code represents SOS as “…—…”. An SOS is distinguished from other Morse communications because it is typically transmitted without any spaces between the letters. SOS is typically repeated numerous times with short intervals between each transmission, making it quite simple to recognize. It is incredibly simple to communicate, memorize, and understand.

Basics of the International System of Morse Code

  • Tiny marks, known as a “dot” or “dit,” that single-time units extend.
  • “Dash” or “dah” long mark (-), 3-time units lengthy.
  • A one-time-unit-long space exists among the dots and dashes that comprise a morse character.
  • There is a three-time unit-long gap between characters.
  • The between-words interval lasts for seven-time units.

Remember that spaces and marks are always in contrast. It is never possible to have two consecutive marks or gaps.

Step-by-Step Process to Learn Morse Code

  • Familiarize yourself with how the alphabet appears in Morse code first. Keep in mind that there are minor variations between the international and American Morse code alphabets.
  • Work on speaking dits and dahs in the right rhythm. Dits produce a tiny, brief sound. Dahs should be more stretched and persist about three times longer than dits.
  • Create smart word associations to help you remember Morse code’s letters and numbers.
  • Listen to Morse code conversation recordings that will give you a better understanding of how the system processes communication. For practicing as a beginner, read through the children’s storybooks page by page and translate the simple sentences into code.
  • Use Morse code to welcome your friend, exchange thoughts, or secretly crack jokes.
  • Additional resources, such as different applications, help you learn and practice whenever possible. Both app-based learning and pen-and-paper exercises will improve your understanding of codes in all their versions.

Translate Morse code using Python

For implementing encryption like morse code, Python offers a data structure known as a dictionary that stores data in key-value pairs. The encryption (Morse code) contains the values of the associated keys, while the plaintext (English Characters) acts as the keys themselves. For decryption, we proceed by adding space at the end of the string that has to be decrypted.

There are many other ways to translate morse code, such as using an online tool that takes less than a second to convert morse code into simple text.

Practical Uses of Morse code

  • Patients with limited single-finger control can enter text and interact with others using the Wi Morse system based on Morse code.
  • Still now, among amateur radio enthusiasts, Morse code is widely used.
  • The US Navy and National Guard use signal lamps to interact using Morse code.
  • Through short and long blinks, individuals can interact in Morse code via their eyelids.
  • Using a vibrotactile device, the deaf-blind individual can “see” the computer screen by “hearing” Morse code. Because it can be personalized for a person’s unique haptic sensitivity, the vibrotactile Morse code is very practical. Those whose communication ability has been affected by bleeding, cardiac arrest, or paralysis have turned to Morse Code as a substitute.
  • In video games and movies, confidential information is communicated using Morse codes.
