Morse code the secret language

Go ahead and try encoding or decoding some text! It uses short and long pulses - tones or lights - to represent letters and numbers. Probably the most well known Morse Code Message is the one made up of three short pulses, then three long pulses, then three short pulses again. Or "dot dot dot, dash dash dash, dot dot dot.

The signal is "on" when the knob is pressed, and "off" when it is released. Length and timing of the dots and dashes are entirely controlled by the telegraphist. Morse code receiver, recording on paper tape Beginning inthe American artist Samuel F. Morsethe American physicist Joseph Henryand Alfred Vail developed an electrical telegraph system.

This system sent pulses of electric current along wires which controlled an electromagnet that was located at the receiving end of the telegraph system. A code was needed to transmit natural language using only these pulses, and the silence between them.

AroundMorse, therefore, developed an early forerunner to the modern International Morse code. Around the same time, Carl Friedrich Gauss and Wilhelm Eduard Weber as well as Carl August von Steinheil had already used codes with varying word lengths for their telegraphs.

Since aroundEuropean experimenters had been making progress with earlier battery-powered signaling systems in emitting oxygen and hydrogen bubbles through liquid, flipping magnetic semaphore flags, tripping alarms across long distances over wire, and other techniques. The numerous ingenious experimental encoding designs they devised and demonstrated were telegraphic precursors to practical applications.

However, in contrast with any system of making sounds of clicks, their system used pointing needles that rotated above alphabetical charts to indicate the letters that were being sent. InCooke and Wheatstone built a telegraph that printed the letters from a wheel of typefaces struck by a hammer.

This machine was based on their telegraph and worked well; however, they failed to find customers for this system and only two examples were ever built. When an electrical current was received, an electromagnet engaged an armature that pushed a stylus onto the moving paper tape, making an indentation on the tape.

When the current was interrupted, a spring retracted the stylus, and that portion of the moving tape remained unmarked. The Morse code was developed so that operators could translate the indentations marked on the paper tape into text messages.

In his earliest code, Morse had planned to transmit only numerals, and to use a codebook to look up each word according to the number which had been sent. However, the code was soon expanded by Alfred Vail in to include letters and special characters, so it could be used more generally.

Vail estimated the frequency of use of letters in the English language by counting the movable type he found in the type-cases of a local newspaper in Morristown. This code was used since and became known as Morse landline code or American Morse code.

Comparison of historical versions of Morse code with the current standard. American Morse code as originally defined. The modified and rationalized version used by Gerke on German railways.

The current ITU standard. The telegraph operators soon learned that they could translate the clicks directly into dots and dashes, and write these down by hand, thus making the paper tape unnecessary. When Morse code was adapted to radio communicationthe dots and dashes were sent as short and long tone pulses.

It was later found that people become more proficient at receiving Morse code when it is taught as a language that is heard, instead of one read from a page.

Dots which are not the final element of a character became vocalized as "di".

For example, the letter "c" was then vocalized as "dah-di-dah-dit".Since the language is considered a valuable part of American history, there is some concern that it's beginning to die out.

However, the few remaining speakers of it seem intent on keeping it alive -- . One last secret language, sort of. Our family jokes that our secret family code phrase is, “The black cat crows at dawn.” In reality, we have a handful of codes that are more versatile than a sentence.

Facebook. Twitter. Google Plus. Stumble Upon. It's kind of like Morse code, only simpler, because you can't make a dash sound by tapping your fingers. we don't get it either, but it wouldn't be a very good secret language if we did.

Since the language is considered a valuable part of American. Codes have been used throughout history to communicate, signal distress, and transmit secret information.

One of the most recognizable codes is Morse code, developed by Samuel Morse in as a means of long-distance communication. A Morse code novice would also need to keep a "cheat sheet" until he or she remembers every letter's code, which the captors would likely confiscate.

Tap code can be more easily decoded in one's head by mentally using the table.
