Some mine rescues have used pulling on a rope - a short pull for a dot and a long pull for a dash. Morse code is transmitted using just two states on and off.

Historians have called it the first digital code. Morse code may be represented as a binary code, and that is what telegraph operators do when transmitting messages.

Working from the above ITU definition and further defining a bit as a dot time, a Morse code sequence may be made from a combination of the following five bit-strings:.

Note that the marks and gaps alternate: dots and dashes are always separated by one of the gaps, and that the gaps are always separated by a dot or a dash.

Morse messages are generally transmitted by a hand-operated device such as a telegraph key , so there are variations introduced by the skill of the sender and receiver — more experienced operators can send and receive at faster speeds.

In addition, individual operators differ slightly, for example, using slightly longer or shorter dashes or gaps, perhaps only for particular characters.

This is called their "fist", and experienced operators can recognize specific individuals by it alone. A good operator who sends clearly and is easy to copy is said to have a "good fist".

A "poor fist" is a characteristic of sloppy or hard to copy Morse code. The very long time constants of 19th and early 20th century submarine communications cables required a different form of Morse signalling.

Instead of keying a voltage on and off for varying times, the dits and dahs were represented by two polarities of voltage impressed on the cable, for a uniform time.

Below is an illustration of timing conventions. Morse code is often spoken or written with "dah" for dashes, "dit" for dots located at the end of a character, and "di" for dots located at the beginning or internally within the character.

Thus, the following Morse code sequence:. Dah-dah dah-dah-dah di-dah-dit di-di-dit dit, Dah-di-dah-dit dah-dah-dah dah-di-dit dit.

There is little point in learning to read written Morse as above; rather, the sounds of all of the letters and symbols need to be learned, for both sending and receiving.

All Morse code elements depend on the dot length. A dash is the length of 3 dots, and spacings are specified in number of dot lengths. Specifying the dot duration is, however, not the common practice.

Usually, speeds are stated in words per minute. That introduces ambiguity because words have different numbers of characters, and characters have different dot lengths.

It is not immediately clear how a specific word rate determines the dot duration in milliseconds. Some method to standardize the transformation of a word rate to a dot duration is useful.

A simple way to do this is to choose a dot duration that would send a typical word the desired number of times in one minute. If, for example, the operator wanted a character speed of 13 words per minute, the operator would choose a dot rate that would send the typical word 13 times in exactly one minute.

The typical word thus determines the dot length. It is common to assume that a word is 5 characters long.

PARIS mimics a word rate that is typical of natural language words and reflects the benefits of Morse code's shorter code durations for common characters such as "e" and "t".

CODEX offers a word rate that is typical of 5-letter code groups sequences of random letters. Using the word PARIS as a standard, the number of dot units is 50 and a simple calculation shows that the dot length at 20 words per minute is 60 milliseconds.

Because Morse code is usually sent by hand, it is unlikely that an operator could be that precise with the dot length, and the individual characteristics and preferences of the operators usually override the standards.

For commercial radiotelegraph licenses in the United States, the Federal Communications Commission specifies tests for Morse code proficiency in words per minute and in code groups per minute.

The Commission specifies Morse code test elements at 16 code groups per minute, 20 words per minute, 20 code groups per minute, and 25 words per minute.

While the Federal Communications Commission no longer requires Morse code for amateur radio licenses, the old requirements were similar to the requirements for commercial radiotelegraph licenses.

A difference between amateur radio licenses and commercial radiotelegraph licenses is that commercial operators must be able to receive code groups of random characters along with plain language text.

For each class of license, the code group speed requirement is slower than the plain language text requirement. For example, for the Radiotelegraph Operator License, the examinee must pass a 20 word per minute plain text test and a 16 word per minute code group test.

Based upon a 50 dot duration standard word such as PARIS, the time for one dot duration or one unit can be computed by the formula:.

Where: T is the unit time, or dot duration in milliseconds, and W is the speed in wpm. Sometimes, especially while teaching Morse code, the timing rules above are changed so two different speeds are used: a character speed and a text speed.

The character speed is how fast each individual letter is sent. The text speed is how fast the entire message is sent.

For example, individual characters may be sent at a 13 words-per-minute rate, but the intercharacter and interword gaps may be lengthened so the word rate is only 5 words per minute.

Using different character and text speeds is, in fact, a common practice, and is used in the Farnsworth method of learning Morse code. Some methods of teaching Morse code use a dichotomic search table.

People learning Morse code using the Farnsworth method are taught to send and receive letters and other symbols at their full target speed, that is with normal relative timing of the dots, dashes, and spaces within each symbol for that speed.

The Farnsworth method is named for Donald R. However, initially exaggerated spaces between symbols and words are used, to give "thinking time" to make the sound "shape" of the letters and symbols easier to learn.

The spacing can then be reduced with practice and familiarity. Another popular teaching method is the Koch method , named after German psychologist Ludwig Koch, which uses the full target speed from the outset but begins with just two characters.

In North America, many thousands of individuals have increased their code recognition speed after initial memorization of the characters by listening to the regularly scheduled code practice transmissions broadcast by W1AW , the American Radio Relay League's headquarters station.

Visual mnemonic charts have been devised over the ages. Baden-Powell included one in the Girl Guides handbook [55] in In the United Kingdom, many people learned the Morse code by means of a series of words or phrases that have the same rhythm as a Morse character.

For instance, "Q" in Morse is dah-dah-di-dah, which can be memorized by the phrase "God save the Queen", and the Morse for "F" is di-di-dah-dit, which can be memorized as "Did she like it.

A well-known Morse code rhythm from the Second World War period derives from Beethoven 's Fifth Symphony , the opening phrase of which was regularly played at the beginning of BBC broadcasts.

The timing of the notes corresponds to the Morse for "V", di-di-di-dah, understood as "V for Victory" as well as the Roman numeral for the number five.

Prosigns for Morse code are special usually unwritten procedural signals or symbols that are used to indicate changes in communications protocol status or white space text formatting actions.

The symbols! The symbol was formally added in There is no standard representation for the exclamation mark!

For Chinese , Chinese telegraph code is used to map Chinese characters to four-digit codes and send these digits out using standard Morse code.

SKATS maps hangul characters to arbitrary letters of the Latin script and has no relationship to pronunciation in Korean.

For Russian and Bulgarian, Russian Morse code is used to map the Cyrillic characters to four-element codes. During early World War I — , Germany briefly experimented with 'dotty' and 'dashy' Morse, in essence adding a dot or a dash at the end of each Morse symbol.

Only a small percentage of Western Front North Atlantic and Mediterranean Sea traffic was in 'dotty' or 'dashy' Morse during the entire war.

Kahn's cited sources come from the popular press and wireless magazines of the time. Other forms of 'Fractional Morse' or 'Fractionated Morse' have emerged.

Decoding software for Morse code ranges from software-defined wide-band radio receivers coupled to the Reverse Beacon Network, [61] which decodes signals and detects CQ messages on ham bands , to smartphone applications.

International Morse code today is most popular among amateur radio operators, in the mode commonly referred to as " continuous wave " or "CW". This name was chosen to distinguish it from the damped wave emissions from spark transmitters, not because the transmission is continuous.

Other keying methods are available in radio telegraphy, such as frequency-shift keying. The original amateur radio operators used Morse code exclusively since voice-capable radio transmitters did not become commonly available until around Until , the International Telecommunication Union mandated Morse code proficiency as part of the amateur radio licensing procedure worldwide.

However, the World Radiocommunication Conference of made the Morse code requirement for amateur radio licensing optional.

Until , a demonstration of the ability to send and receive Morse code at a minimum of five words per minute wpm was required to receive an amateur radio license for use in the United States from the Federal Communications Commission.

Demonstration of this ability was still required for the privilege to use the HF bands. Until , proficiency at the 20 wpm level was required to receive the highest level of amateur license Amateur Extra Class ; effective April 15, , the FCC reduced the Extra Class requirement to five wpm.

While voice and data transmissions are limited to specific amateur radio bands under U. In some countries, certain portions of the amateur radio bands are reserved for transmission of Morse code signals only.

Because Morse code transmissions employ an on-off keyed radio signal, it requires less complex transmission equipment than other forms of radio communication.

The fact that the transmitted power is concentrated into a very limited bandwidth makes it possible to use narrow receiver filters, which suppress or eliminate interference on nearby frequencies.

The narrow signal bandwidth also takes advantage of the natural aural selectivity of the human brain, further enhancing weak signal readability.

This efficiency makes CW extremely useful for DX distance transmissions , as well as for low-power transmissions commonly called " QRP operation ", from the Q-code for "reduce power".

There are several amateur clubs that require solid high speed copy, the highest of these has a standard of 60 WPM.

The American Radio Relay League offers a code proficiency certification program that starts at 10 wpm.

The relatively limited speed at which Morse code can be sent led to the development of an extensive number of abbreviations to speed communication.

These include prosigns, Q codes , and a set of Morse code abbreviations for typical message components.

For example, CQ is broadcast to be interpreted as "seek you" I'd like to converse with anyone who can hear my signal. The use of abbreviations for common terms permits conversation even when the operators speak different languages.

Although the traditional telegraph key straight key is still used by some amateurs, the use of mechanical semi-automatic keyers known as "bugs" and of fully automatic electronic keyers is prevalent today.

Software is also frequently employed to produce and decode Morse code radio signals. Some programs like WinMorse [41] have implemented the standard.

Navy , have long used signal lamps to exchange messages in Morse code. Modern use continues, in part, as a way to communicate while maintaining radio silence.

Many amateur radio repeaters identify with Morse, even though they are used for voice communications. This can be sent many ways: keying a radio on and off, flashing a mirror, toggling a flashlight, and similar methods.

SOS is not three separate characters, rather, it is a prosign SOS , and is keyed without gaps between characters.

Morse code has been employed as an assistive technology , helping people with a variety of disabilities to communicate.

For example, the Android operating system versions 5. Morse can be sent by persons with severe motion disabilities, as long as they have some minimal motor control.

An original solution to the problem that caretakers have to learn to decode has been an electronic typewriter with the codes written on the keys.

Codes were sung by users; see the voice typewriter employing morse or votem, Newell and Nabarro, Morse code can also be translated by computer and used in a speaking communication aid.

In some cases, this means alternately blowing into and sucking on a plastic tube " sip-and-puff " interface. An important advantage of Morse code over row column scanning is that once learned, it does not require looking at a display.

Also, it appears faster than scanning. In one case reported in the radio amateur magazine QST , [47] an old shipboard radio operator who had a stroke and lost the ability to speak or write could communicate with his physician a radio amateur by blinking his eyes in Morse.

In these two cases, interpreters were available to understand those series of eye-blinks. International Morse code is composed of five elements: [1].

Morse code can be transmitted in a number of ways: originally as electrical pulses along a telegraph wire, but also as an audio tone, a radio signal with short and long tones, or as a mechanical, audible, or visual signal e.
