"For instance, the international code has only two symbols, dots and dashes, but the American code has several lengths of dash. There is a distinction between ""L"" () and ""T"" (). Also, in the international code the space between symbols within a character is always the same, but American Morse has two different spaces. The letters ""S"" (), ""C"" (), and ""R"" () all consist of three dots, but the timing is different in each case. A frequently quoted, but possibly apocryphal, story from the historical period concerns the similarity of ""L"" and ""T"" in the American code. A company"

"Morse code Morse code is a character encoding scheme used in telecommunication that encodes text characters as standardized sequences of two different signal durations called ""dots"" and ""dashes"" or ""dits"" and ""dahs"". Morse code is named for Samuel F. B. Morse, an inventor of the telegraph. The International Morse Code encodes the ISO basic Latin alphabet, some extra Latin letters, the Arabic numerals and a small set of punctuation and procedural signals (prosigns). Each Morse code symbol is formed by a sequence of dots and dashes. The dot duration is the basic unit of time measurement in Morse code transmission."

The distress signal is a continuous sequence of three dots, three dashes, and three dots, with no spaces between the letters (notated by the overscore).

"receiving Morse code when it is taught as a language that is heard, instead of one read from a page. To reflect the sounds of Morse code receivers, the operators began to vocalize a dot as ""dit"", and a dash as ""dah"". 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"". Morse code was sometimes facetiously known as ""iddy-umpty"", and a dash as ""umpty"", leading to the word ""umpteen"". The Morse code, as it is used internationally today, was derived from a much refined proposal"
"in Morse code format, would normally be written something like this, where – represents dahs and · represents dits: Next is the exact conventional timing for this phrase, with = representing ""signal on"", and . representing ""signal off"", each for the time length of exactly one dit: 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.

Morse code can be memorized, and Morse code signalling in a form perceptible to the human senses, such as sound waves or visible light, can be directly interpreted by persons trained in the skill. Because many non-English natural languages use other than the 26 Roman letters, Morse alphabets have been developed for those languages. In an emergency, Morse code can be generated by improvised methods such as turning a light on and off, tapping on an object or sounding a horn or whistle, making it one of the simplest"
"One simply raises the Kilo flag (see diagram at the top), or sends the Morse Code equivalent (dash-dot-dash) by flashing light; this has the assigned message of ""I wish to communicate with you."" One practical application of the ICS is that all of the standardized messages come in nine languages (English, French, Italian, German, Japanese, Spanish, Norwegian, and, since 1969, Russian and Greek). This fact is immaterial if the sender and receiver(s) are using different languages; each language has a book with equivalent messages keyed to the same code.

The course lights turn on for 0.5 second for a dot, 1.5 second for a dash with a 0.5 second between each dot or dash. A pause of 1.5 seconds separates each letter.

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"
"the form of a short line of dashes and dots forming a Morse character radiating away from the location of the beacon. Typically, the Morse character starts with a dash - a long, continuous signal. The proposal for Enhanced RACON is to further modulate this first dash, with a small amount of digital information to enable either the unique identification of this particular RACON (for instance 30 bits of data identifying the RACON by a MMSI) or alternatively to identify the position of the RACON. Introducing a unique identification would enable enhanced RADAR positioning through the ability to correlate the"

The number sign takes the place of spaces within a number such as a serial number. For example, ""A (46 1)"" is transcribed .

(In American Morse code, which was used by many coastal ships in the United States through the first part of the twentieth century, three dashes stood for the numeral """"5"""", so in a few cases the distress signal was informally referred to as """"S 5 S"""".) In contrast to CQD, which was sent as three separate letters with spaces between each letter, the ' distress call has always been transmitted as a continuous sequence ""dits"" and ""dahs"", and not as individual letters. There was no problem as long as operators were aware that"
"Convention, held in Berlin in 1906, Germany's """" distress signal of three-dots/three-dashes/three-dots () was adopted as the international Morse code distress signal. (This distress signal soon became known as ""SOS"" because if gaps are inserted it can be thought of as the Morse codes for those letters – by contrast CQD is transmitted as three distinct letters with a short gap between each. Germany had first adopted this distress signal in regulations effective 1 April 1905.) Between 1899 and 1908, nine documented rescues were made by the use of wireless. The earliest of these was a distress call from the"
"CQD appears to have died out thereafter. In both the 1 April 1905 German law and the 1906 international regulations, the distress signal was specified as a continuous Morse code sequence of three dots / three dashes / three dots, with no mention of any alphabetic equivalents. However, in International Morse, three dots comprise the letter """"S"""", and three dashes the letter """"O"""". It therefore soon became common to refer to the distress signal as """"S O S"""". An early report on The International Radio-Telegraphic Convention in the 12 January 1907, ""Electrical World"" stated that ""Vessels in distress use the"

In these two cases, interpreters were available to understand those series of eye-blinks. International Morse code is composed of five elements: 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.g. a flashing light) using devices like an Aldis lamp or"
"the notation """" is just a convenient way for remembering the proper sequence of the distress signal's total of nine dits and dahs. In later years, the number of special Morse symbols increased. In order to designate the proper sequence of dits and dahs for a long special symbol, the standard practice is to list alphabetic characters that contain the same series of dits and dahs, in the same order, with a bar atop the character sequence to indicate that the sequence is a digraph and there should not be any internal spaces in the transmission. Thus, under the modern"
"Dot-decimal notation Dot-decimal notation is a presentation format for numerical data. It consists of a string of decimal numbers, each pair separated by a full stop (""dot""). A common use of dot-decimal notation is in information technology where it is a method of writing numbers in octet-grouped base-10 (decimal) numbers separated by dots (full stops). In computer networking, Internet Protocol Version 4 addresses (IPv4 addresses) are commonly written using the quad-dotted notation of four decimal integers, ranging from 0 to 255 each. Dot-decimal notation is a presentation format for numerical data expressed as a string of decimal numbers each separated"

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).

"thus determines the dot length. It is common to assume that a word is 5 characters long. There are two common typical words: ""PARIS"" and ""CODEX"". 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"

Various Morse letters could also be sent, for example to notify an aircrew their Mosquito was within a range of the target. The Mouse station sent five dots and a dash to indicate bomb release. The Mouse station included a bombsight computer, known as ""Micestro"", to determine the proper release time, there being no particular logic in carrying the bombsight on the Mosquito when it was under the control of the ground station.

In 1975 the assembly of the IMO decided that the 1974 convention should in future use SI (metric) units only. In particular, amendments in 1988 based on amendments of International Radio Regulations in 1987 replaced Morse code with the Global Maritime Distress Safety System"

The underline, along with its joining, are analogous to the number of flags and beaming in standard notation. So are dotted notes. But the analogue stops at notes worth three quarter notes and beyond, where dashes are used instead. The number ""0"" represents the musical rest. The rules for length is similar to that of the note, except that it is customary"

For example, beacon number 15 would have a code digit of 5 (the units digit), hence the letter ""R"", and Morse code: ""dit dah dit"" (·−·). Airway beacons were constructed by the Post Office and the Department of Commerce between 1923 and 1933. The Low Frequency Radio Range system began to replace this visual system in 1929. The last visual airway beacon was supposedly shut down in 1973, but some airway beacons are still operating in Western Montana and are charted on the"
