href="/wiki/Character_encoding" title="Character encoding">encodes</a> <a href="/wiki/Written_language" title="Written language">text</a> characters as standardized sequences of two different signal durations, called dots and dashes, or dits and dahs.<a href="#cite_note-Beechey-1876-3">[3]</a><a href="#cite_note-Camm-1941-4">[4]</a> Morse code is named after <a href="/wiki/Samuel_Morse" title="Samuel Morse">Samuel Morse</a>, one of the early developers of the system adopted for <a href="/wiki/Electrical_telegraph" title="Electrical telegraph">electrical telegraphy</a>. International Morse code encodes the 26 <a href="/wiki/ISO_basic_Latin_alphabet" title="ISO basic Latin alphabet">basic Latin letters</a> A to Z, one <a href="/wiki/Diacritic" title="Diacritic">accented</a> Latin letter (É), the <a href="/wiki/Arabic_numerals" title="Arabic numerals">Arabic numerals</a>, and a small set of punctuation and procedural signals (<a href="/wiki/Prosigns_for_Morse_code" title="Prosigns for Morse code">prosigns</a>). There is no distinction between upper and lower case letters.<a href="#cite_note-ITU-R-M-1677-1">[1]</a> Each Morse code symbol is formed by a sequence of dits and dahs. The dit duration can vary for signal clarity and operator skill, but for any one message, once established it is the basic unit of time measurement in Morse code. The duration of a dah is three times the duration of a dit (although some telegraphers deliberately exaggerate the length of a dah for clearer signalling). Each dit or dah within an encoded character is followed by a period of signal absence, called a space, equal to the dit duration. The letters of a word are <a href="/wiki/Delimiter" title="Delimiter">separated by</a> a space of duration equal to three dits, and words are separated by a space equal to seven dits.<a href="#cite_note-ITU-R-M-1677-1">[1]</a><a href="#cite_note-TR-Paris-1949-5">[5]</a><a href="#cite_note-7">[a]</a> Morse code can be memorized and sent in a form perceptible to the human senses, e.g. via sound waves or visible light, such that it can be directly interpreted by persons trained in the skill.<a href="#cite_note-Army-1968-TM-11-459-8">[7]</a><a href="#cite_note-Navy-1957-RM32-10228B-9">[8]</a> Morse code is usually transmitted by <a href="/wiki/On-off_keying" class="mw-redirect" title="On-off keying">on-off keying</a> of an information-carrying medium such as electric current, radio waves, visible light, or sound waves.<a href="#cite_note-Preece-Sivewright-1891-10">[9]</a><a href="#cite_note-Army-1939-FM-24-5-11">[10]</a> The current or wave is present during the time period of the dit or dah and absent during the time between dits and dahs.<a href="#cite_note-Everitt-1937-12">[11]</a><a href="#cite_note-Radio-mag-Handbook-1940-13">[12]</a> Since many natural languages use more than the 26 letters of the <a href="/wiki/Latin_alphabet" title="Latin alphabet">Latin alphabet</a>, <a href="/wiki/Morse_code_for_non-Latin_alphabets" title="Morse code for non-Latin alphabets">Morse alphabets</a> have been developed for those languages, largely by transliteration of existing codes.<a href="#cite_note-War-1943-TM-11-459-14">[13]</a> To increase the efficiency of transmission, Morse code was originally designed so that the duration of each symbol is approximately <a href="/wiki/Entropy_encoding" class="mw-redirect" title="Entropy encoding">inverse to the frequency of occurrence</a> of the character that it represents in text of the English language. Thus the most common letter in English, the letter E, has the shortest code – a single dit. Because the Morse code elements are specified by proportion rather than specific time durations, the code is usually transmitted at the highest rate that the receiver is capable of decoding. Morse code transmission rate (speed) is specified in groups per minute, commonly referred to as words per minute.<a href="#cite_note-15">[b]</a><a href="#cite_note-Army-1968-TM-11-459-8">[7]</a> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Development_and_history">Development and history</h2></div> <div class="mw-heading mw-heading3"><h3 id="Pre-Morse_telegraphs_and_codes">Pre-Morse telegraphs and codes</h3></div> <figure class="mw-halign-left" typeof="mw:File/Thumb"><a href="/wiki/File:Single_needle_telegraph_(Rankin_Kennedy,_Electrical_Installations,_Vol_V,_1903).jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/b/b2/Single_needle_telegraph_%28Rankin_Kennedy%2C_Electrical_Installations%2C_Vol_V%2C_1903%29.jpg/200px-Single_needle_telegraph_%28Rankin_Kennedy%2C_Electrical_Installations%2C_Vol_V%2C_1903%29.jpg" decoding="async" width="200" height="231" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/b/b2/Single_needle_telegraph_%28Rankin_Kennedy%2C_Electrical_Installations%2C_Vol_V%2C_1903%29.jpg/300px-Single_needle_telegraph_%28Rankin_Kennedy%2C_Electrical_Installations%2C_Vol_V%2C_1903%29.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/b/b2/Single_needle_telegraph_%28Rankin_Kennedy%2C_Electrical_Installations%2C_Vol_V%2C_1903%29.jpg/400px-Single_needle_telegraph_%28Rankin_Kennedy%2C_Electrical_Installations%2C_Vol_V%2C_1903%29.jpg 2x" data-file-width="798" data-file-height="923" /></a><figcaption>Single needle telegraph instrument</figcaption></figure> Early in the nineteenth century, European experimenters made progress with electrical signaling systems, using a variety of techniques including <a href="/wiki/Static_electricity" title="Static electricity">static electricity</a> and electricity from <a href="/wiki/Voltaic_pile" title="Voltaic pile">Voltaic piles</a> producing <a href="/wiki/Electrochemistry" title="Electrochemistry">electrochemical</a> and <a href="/wiki/Electromagnetism" title="Electromagnetism">electromagnetic</a> changes.

Pulses of <a href="/wiki/Electric_current" title="Electric current">electric current</a> were sent along wires to control an electromagnet in the receiving instrument. Many of the earliest telegraph systems used a single-needle system which gave a very simple and robust instrument. However, it was slow, as the receiving operator had to alternate between looking at the needle and writing down the message.

The simple "on or off" nature of its signals made it desirable to find a method of transmitting natural language using only electrical pulses and the silence between them. Around 1837, Morse therefore developed such a method, an early forerunner to the modern International Morse code.<a href="#cite_note-Burns-2004-20">[18]</a>: 79  The Morse system for <a href="/wiki/Telegraphy" title="Telegraphy">telegraphy</a>, which was first used in about 1844, was designed to make indentations on a paper tape when electric currents were received. Morse's original telegraph receiver used a mechanical clockwork to move a paper tape. 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. Morse code was developed so that operators could translate the indentations marked on the paper tape into text messages. In his earliest design for a 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 <a href="/wiki/Alfred_Vail" title="Alfred Vail">Alfred Vail</a> in 1840 to include letters and special characters, so it could be used more generally. Vail estimated the frequency of use of letters in the <a href="/wiki/English_language" title="English language">English language</a> by counting the movable type he found in the type-cases of a local newspaper in <a href="/wiki/Morristown,_New_Jersey" title="Morristown, New Jersey">Morristown, New Jersey</a>.<a href="#cite_note-Burns-2004-20">[18]</a>: 84  The shorter marks were called "dots" and the longer ones "dashes", and the letters most commonly used were assigned the shortest sequences of dots and dashes. This code, first used in 1844, was what later became known as Morse landline code, <a href="/wiki/American_Morse_code" title="American Morse code">American Morse code</a>, or Railroad Morse, until the end of railroad telegraphy in the U.S. in the 1970s.[<a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed">citation needed</a>] <div class="mw-heading mw-heading3"><h3 id="Operator-led_change_from_graphical_to_audible_code">Operator-led change from graphical to audible code</h3></div> In the original Morse telegraph system, the receiver's armature made a clicking noise as it moved in and out of position to mark the paper tape. Early 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 <a href="/wiki/Radio_communication" class="mw-redirect" title="Radio communication">radio communication</a>, the dots and dashes were sent as short and long tone pulses. Later telegraphy training found that people become more proficient at receiving Morse code when it is taught "like a language", with each code perceived as a whole "word" instead of a sequence of separate dots and dashes, such as might be shown on a page.<a href="#cite_note-ARRL-Learning-Morse-21">[19]</a> With the advent of tones produced by radiotelegraph receivers, the operators began to vocalize a dot as dit, and a dash as dah, to reflect the sounds of Morse code they heard. To conform to normal sending speed, dits which are not the last element of a code became voiced as di. For example, the letter L (  ▄ ▄▄▄ ▄ ▄ ) is voiced as di dah di dit.<a href="#cite_note-Carron-1986-22">[20]</a><a href="#cite_note-Eckersley-1985-23">[21]</a> Morse code was sometimes facetiously known as "iddy-umpty", a dit lampooned as "iddy" and a dah as "umpty", leading to the word "<a href="/wiki/Umpteen" class="mw-redirect" title="Umpteen">umpteen</a>".<a href="#cite_note-OED-iddy-umpty-24">[22]</a> <figure typeof="mw:File/Thumb"><a href="/wiki/File:Morse_comparison.svg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/5/5a/Morse_comparison.svg/350px-Morse_comparison.svg.png" decoding="async" width="350" height="475" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/5/5a/Morse_comparison.svg/525px-Morse_comparison.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/5/5a/Morse_comparison.svg/700px-Morse_comparison.svg.png 2x" data-file-width="1087" data-file-height="1476" /></a><figcaption>Comparison of historical versions of Morse code with the current standard.

Gerke changed many of the codepoints, in the process doing away with the different length dashes and different inter-element spaces of <a href="/wiki/American_Morse_code" title="American Morse code">American Morse</a>, leaving only two coding elements, the dot and the dash. Codes for <a href="/wiki/German_language" title="German language">German</a> <a href="/wiki/Umlaut_(linguistics)" title="Umlaut (linguistics)">umlauted</a> vowels and CH were introduced. Gerke's code was adopted in Germany and Austria in 1851.<a href="#cite_note-Deutsch-Österreich-Telegr-1851-25">[23]</a> This finally led to the International Morse code in 1865. The International Morse code adopted most of Gerke's codepoints. The codes for O and P were taken from a code system developed by Steinheil. A new codepoint was added for J since Gerke did not distinguish between I and J. Changes were also made to X, Y, and Z. This left only four codepoints identical to the original Morse code, namely E, H, K and N, and the latter two had their dahs extended to full length.

In the late 19th and early 20th centuries, most high-speed international communication used Morse code on telegraph lines, undersea cables, and radio circuits. Although previous transmitters were bulky and the <a href="/wiki/Spark-gap_transmitter" title="Spark-gap transmitter">spark gap system of transmission</a> was dangerous and difficult to use, there had been some early attempts: In 1910, the U.S. Navy experimented with sending Morse from an airplane.<a href="#cite_note-Howeth-1963-26">[24]</a> However the first regular aviation radiotelegraphy was on <a href="/wiki/Airship" title="Airship">airships</a>, which had space to accommodate the large, heavy radio equipment then in use. The same year, 1910, a radio on the airship <a href="/wiki/America_(airship)" title="America (airship)">America</a> was instrumental in coordinating the rescue of its crew.<a href="#cite_note-K2TQN-blog-27">[25]</a> During <a href="/wiki/World_War_I" title="World War I">World War I</a>, <a href="/wiki/Zeppelin" title="Zeppelin">Zeppelin airships</a> equipped with radio were used for bombing and naval scouting,<a href="#cite_note-Pop-Sci-1918-04-Zeppelin-28">[26]</a> and ground-based radio direction finders were used for airship navigation.<a href="#cite_note-Pop-Sci-1918-04-Zeppelin-28">[26]</a> Allied airships and military aircraft also made some use of radiotelegraphy. However, there was little aeronautical radio in general use during <a href="/wiki/World_War_I" title="World War I">World War I</a>, and in the 1920s, there was no radio system used by such important flights as that of <a href="/wiki/Charles_Lindbergh" title="Charles Lindbergh">Charles Lindbergh</a> from <a href="/wiki/New_York_City" title="New York City">New York</a> to <a href="/wiki/Paris" title="Paris">Paris</a> in 1927. Once he and the <a href="/wiki/Spirit_of_St._Louis" title="Spirit of St. Louis">Spirit of St. Louis</a> were off the ground, Lindbergh was truly incommunicado and alone. Morse code in aviation began regular use in the mid-1920s. By 1928, when the first airplane flight was made by the <a href="/wiki/Southern_Cross_(aircraft)" title="Southern Cross (aircraft)">Southern Cross</a> from California to Australia, one of its four crewmen was a radio operator who communicated with ground stations via <a href="/wiki/Wireless_telegraphy" title="Wireless telegraphy">radio telegraph</a>. Beginning in the 1930s, both civilian and military pilots were required to be able to use Morse code, both for use with early communications systems and for identification of navigational beacons that transmitted continuous two- or three-letter identifiers in Morse code. <a href="/wiki/Aeronautical_chart" title="Aeronautical chart">Aeronautical charts</a> show the identifier of each navigational aid next to its location on the map. In addition, rapidly moving field armies could not have fought effectively without radiotelegraphy; they moved more quickly than their communications services could put up new telegraph and telephone lines.

Characters have differing lengths because they contain differing numbers of dits and dahs. Consequently, words also have different lengths in terms of dot duration, even when they contain the same number of characters. For this reason, some standard word is adopted for measuring operators' transmission speeds: Two such standard words in common use are PARIS and CODEX.<a href="#cite_note-Perera-W1TP-Teleg-Mus-36">[33]</a> Operators skilled in Morse code can often understand ("copy") code in their heads at rates in excess of 40 WPM. In addition to knowing, understanding, and being able to copy the standard written alpha-numeric and punctuation characters or symbols at high speeds, skilled high-speed operators must also be fully knowledgeable of all of the special unwritten Morse code symbols for the standard <a href="/wiki/Prosigns_for_Morse_code" title="Prosigns for Morse code">Prosigns for Morse code</a> and the meanings of these special procedural signals in standard Morse code <a href="/wiki/Communications_protocol" class="mw-redirect" title="Communications protocol">communications protocol</a>. International contests in code copying are still occasionally held. In July 1939 at a contest in <a href="/wiki/Asheville,_North_Carolina" title="Asheville, North Carolina">Asheville, North Carolina</a> in the United States, Theodore Roosevelt McElroy (W1JYN) set a still-standing record for Morse copying, 75.2 WPM.<a href="#cite_note-Pierpont-N0HFF-2004-37">[34]</a> Pierpont (2004) also notes that some operators may have passed 100 WPM.<a href="#cite_note-Pierpont-N0HFF-2004-37">[34]</a> By this time, they are "hearing" phrases and sentences rather than words. The fastest speed ever sent by a straight key was achieved in 1942 by Harry Turner (<a href="/wiki/Call_sign" title="Call sign">W9YZE</a>) (d. 1992) who reached 35 WPM in a demonstration at a U.S. Army base. To accurately compare code copying speed records of different eras it is useful to keep in mind that different standard words (50 dit durations versus 60 dit durations) and different interword gaps (5 dit durations versus 7 dit durations) may have been used when determining such speed records. For example, speeds run with the CODEX standard word and the PARIS standard may differ by up to 20%. Today among amateur operators there are several organizations that recognize high-speed code ability, one group consisting of those who can copy Morse at 60 WPM.<a href="#cite_note-Morsecode-NL-EHSC-38">[35]</a> Also, Certificates of Code Proficiency are issued by several amateur radio societies, including the <a href="/wiki/American_Radio_Relay_League" title="American Radio Relay League">American Radio Relay League</a>.

The First Class license required 20 WPM code group and 25 WPM text code proficiency, the others 16 WPM code group test (five letter blocks sent as simulation of receiving encrypted text) and 20 WPM code text (plain language) test. It was also necessary to pass written tests on operating practice and electronics theory. A unique additional demand for the First Class was a requirement of a year of experience for operators of shipboard and coast stations using Morse. This allowed the holder to be chief operator on board a passenger ship. However, since 1999 the use of satellite and very high-frequency maritime communications systems (<a href="/wiki/GMDSS" class="mw-redirect" title="GMDSS">GMDSS</a>) has made them obsolete. (By that point meeting experience requirement for the First was very difficult.) Currently, only one class of license, the Radiotelegraph Operator License, is issued. This is granted either when the tests are passed or as the Second and First are renewed and become this lifetime license. For new applicants, it requires passing a written examination on electronic theory and radiotelegraphy practices, as well as 16 WPM code-group and 20 WPM text tests. However, the code exams are currently waived for holders of Amateur Extra Class licenses who obtained their operating privileges under the old 20 WPM test requirement. <div class="mw-heading mw-heading2"><h2 id="International_Morse_code">International Morse code</h2></div> Morse codes of one version or another have been in use for more than 160 years — longer than any other <a href="/wiki/Electrical" class="mw-redirect" title="Electrical">electrical</a> message encoding system. What is called Morse code today is actually somewhat different from what was originally developed by Vail and Morse. The Modern International Morse code, or continental code, was created by <a href="/wiki/Friedrich_Clemens_Gerke" title="Friedrich Clemens Gerke">Friedrich Clemens Gerke</a> in 1848 and initially used for telegraphy between <a href="/wiki/Hamburg" title="Hamburg">Hamburg</a> and <a href="/wiki/Cuxhaven" title="Cuxhaven">Cuxhaven</a> in Germany.

After some minor changes to the letters and a complete revision of the numerals, International Morse Code was standardized by the International Telegraphy Congress in 1865 in Paris, and later became the standard adopted by the <a href="/wiki/International_Telecommunication_Union" title="International Telecommunication Union">International Telecommunication Union</a> (ITU). Morse and Vail's final code specification, however, was only really used only for land-line telegraphy in the United States and Canada, with the International code used everywhere else, including all ships at sea and sailing in North American waters. Morse's version became known as <a href="/wiki/American_Morse_code" title="American Morse code">American Morse code</a> or railroad code, and is now almost never used, with the possible exception of historical re-enactments. <div class="mw-heading mw-heading3"><h3 id="Aviation">Aviation</h3></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:VFR_Chart_Cayo_Largo_Del_Sur_VOR-DME.png" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/1/1a/VFR_Chart_Cayo_Largo_Del_Sur_VOR-DME.png/220px-VFR_Chart_Cayo_Largo_Del_Sur_VOR-DME.png" decoding="async" width="220" height="186" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/1/1a/VFR_Chart_Cayo_Largo_Del_Sur_VOR-DME.png/330px-VFR_Chart_Cayo_Largo_Del_Sur_VOR-DME.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/1/1a/VFR_Chart_Cayo_Largo_Del_Sur_VOR-DME.png/440px-VFR_Chart_Cayo_Largo_Del_Sur_VOR-DME.png 2x" data-file-width="789" data-file-height="668" /></a><figcaption>Cayo Largo Del Sur VOR-DME</figcaption></figure> In <a href="/wiki/Aviation" title="Aviation">aviation</a>, pilots use <a href="/wiki/Radio_navigation" title="Radio navigation">radio navigation</a> aids. To allow pilots to ensure that the stations they intend to use are serviceable, the stations transmit a set of identification letters (usually a two-to-five-letter version of the station name) in Morse code. Station identification letters are shown on air navigation charts. For example, the <a href="/wiki/VHF_omnidirectional_range" title="VHF omnidirectional range">VOR-DME</a> based at <a href="/wiki/Vilo_Acu%C3%B1a_Airport" title="Vilo Acuña Airport">Vilo Acuña Airport</a> in <a href="/wiki/Cayo_Largo_del_Sur" title="Cayo Largo del Sur">Cayo Largo del Sur, Cuba</a> is identified by "<a href="/wiki/Call_sign" title="Call sign">UCL</a>", and Morse code UCL is repeatedly transmitted on its radio frequency. In some countries, during periods of maintenance, the facility may instead transmit the signal TEST (  ▄▄▄    ▄   ▄ ▄ ▄   ▄▄▄ ), or the <a href="/wiki/Call_sign" title="Call sign">identification</a> may be removed, which tells <a href="/wiki/Aviator" class="mw-redirect" title="Aviator">pilots</a> and <a href="/wiki/Navigator" title="Navigator">navigators</a> that the station is unreliable.

In the U.S., pilots do not actually have to know Morse to identify the transmitter because the dot/dash sequence is written out next to the transmitter's symbol on aeronautical charts. Some modern navigation receivers automatically translate the code into displayed letters.<figure class="mw-default-size mw-halign-right" typeof="mw:File/Thumb"><audio id="mwe_player_0" controls="" preload="none" data-mw-tmh="" class="mw-file-element" width="220" style="width:220px;" data-durationhint="13" data-mwtitle="NonDirectional_Beacon_WG.ogg" data-mwprovider="wikimediacommons" resource="/wiki/File:NonDirectional_Beacon_WG.ogg"><source src="//upload.wikimedia.org/wikipedia/commons/b/b1/NonDirectional_Beacon_WG.ogg" type="audio/ogg; codecs="vorbis"" data-width="0" data-height="0" /><source src="//upload.wikimedia.org/wikipedia/commons/transcoded/b/b1/NonDirectional_Beacon_WG.ogg/NonDirectional_Beacon_WG.ogg.mp3" type="audio/mpeg" data-transcodekey="mp3" data-width="0" data-height="0" /></audio><figcaption>The sound of non-directional beacon WG, on 248 kHz, located at 49.8992 North, 97.349197 West,<a href="#cite_note-Pilotnav-sps-10404-41">[38]</a> near <a href="/wiki/Winnipeg_James_Armstrong_Richardson_International_Airport" title="Winnipeg James Armstrong Richardson International Airport">Winnipeg's main airport</a></figcaption></figure> <div class="mw-heading mw-heading3"><h3 id="Amateur_radio">Amateur radio</h3></div> <figure class="mw-default-size mw-halign-right" typeof="mw:File/Thumb"><a href="/wiki/File:VibroplexBug.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/8/88/VibroplexBug.jpg/220px-VibroplexBug.jpg" decoding="async" width="220" height="154" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/8/88/VibroplexBug.jpg/330px-VibroplexBug.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/8/88/VibroplexBug.jpg 2x" data-file-width="350" data-file-height="245" /></a><figcaption><a href="/wiki/Vibroplex" title="Vibroplex">Vibroplex</a> brand semiautomatic key<a href="#cite_note-bug_op_note-42">[d]</a> (informally called a "bug" since it vaguely resembles a <a href="/wiki/Stick_insect" class="mw-redirect" title="Stick insect">stick insect</a>). </figcaption></figure> International Morse code today is most popular among <a href="/wiki/Amateur_radio" title="Amateur radio">amateur radio</a> operators, in the mode commonly referred to as "<a href="/wiki/Continuous_wave" title="Continuous wave">continuous wave</a>" or "CW".<a href="#cite_note-43">[e]</a> Other, faster keying methods are available in radio telegraphy, such as <a href="/wiki/Frequency-shift_keying" title="Frequency-shift keying">frequency-shift keying</a> (FSK).

Demonstration of this ability was still required for the privilege to use the <a href="/wiki/Shortwave" class="mw-redirect" title="Shortwave">shortwave bands</a>. Until 2000, proficiency at the 20 WPM level was required to receive the highest level of amateur license (Amateur Extra Class); effective April 15, 2000, in the FCC reduced the Extra Class requirement to 5 WPM.<a href="#cite_note-ARRL-2000-Part-97-amended-46">[41]</a> Finally, effective on February 23, 2007, the FCC eliminated the Morse code proficiency requirements from all amateur radio licenses. While voice and data transmissions are limited to specific amateur radio bands under U.S. rules, Morse code is permitted on all amateur bands: <a href="/wiki/2200-meter_band" title="2200-meter band">LF</a>, <a href="/wiki/630-meter_band" title="630-meter band">MF low</a>, <a href="/wiki/160-meter_band" title="160-meter band">MF high</a>, <a href="/wiki/High_frequency" title="High frequency">HF</a>, <a href="/wiki/VHF" class="mw-redirect" title="VHF">VHF</a>, and <a href="/wiki/UHF" class="mw-redirect" title="UHF">UHF</a>. 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 <a href="/wiki/On-off_keying" class="mw-redirect" title="On-off keying">on-off keyed</a> radio signal, it requires less complex equipment than other <a href="/wiki/List_of_amateur_radio_modes" title="List of amateur radio modes">radio transmission modes</a>. Morse code also uses less <a href="/wiki/Signal_bandwidth" class="mw-redirect" title="Signal bandwidth">bandwidth</a> (typically only 100–150 <a href="/wiki/Hertz" title="Hertz">Hz</a> wide, although only for a slow data rate) than voice communication (roughly 2,400~2,800 Hz used by <a href="/wiki/Single-sideband_modulation" title="Single-sideband modulation">SSB voice</a>). Morse code is usually received as a high-pitched audio tone, so transmissions are easier to copy than voice through the noise on congested frequencies, and it can be used in very high noise / low signal environments. 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.[<a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed">citation needed</a>] This efficiency makes CW extremely useful for <a href="/wiki/DXing" title="DXing">DX (long distance) transmissions</a>, as well as for low-power transmissions (commonly called "<a href="/wiki/QRP_operation" title="QRP operation">QRP operation</a>", from the <a href="/wiki/Q-code" class="mw-redirect" title="Q-code">Q-code</a> 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 <a href="/wiki/American_Radio_Relay_League" title="American Radio Relay League">American Radio Relay League</a> 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, <a href="/wiki/Q_code" title="Q code">Q codes</a>, and a set of <a href="/wiki/Morse_code_abbreviations" title="Morse code abbreviations">Morse code abbreviations</a> 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 abbreviations OM (old man), YL (young lady), and XYL ("ex-young lady" – wife) are common. YL or OM is used by an operator when referring to the other operator (regardless of their actual age), and XYL or OM (rather than the expected XYM) is used by an operator when referring to his or her spouse. QTH is "transmitting location" (spoken "my Q.T.H." is "my location"). The use of abbreviations for common terms permits conversation even when the operators speak different languages. Although the traditional <a href="/wiki/Telegraph_key" title="Telegraph key">telegraph key</a> (straight key) is still used by some amateurs, the use of mechanical semi-automatic <a href="/wiki/Keyer" title="Keyer">keyers</a><a href="#cite_note-bug_op_note-42">[d]</a> (informally called "bugs"), and of fully automatic electronic <a href="/wiki/Keyer" title="Keyer">keyers</a> (called "single paddle" and either "double-paddle" or "iambic" keys) is prevalent today. <a href="/wiki/Software" title="Software">Software</a> is also frequently employed to produce and decode Morse code radio signals.

Some mine rescues have used pulling on a rope - a short pull for a dot and a long pull for a dah. Ground forces send messages to aircraft with panel signalling, where a horizontal panel is a dah and a vertical panel a dit.<a href="#cite_note-61">[55]</a> Morse messages are generally transmitted by a hand-operated device such as a <a href="/wiki/Telegraph_key" title="Telegraph key">telegraph key</a>, 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 dahs 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. <div class="mw-heading mw-heading4"><h4 id="Digital_storage">Digital storage</h4></div> Morse code is transmitted using just two states (on and off). 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 <a href="/wiki/Bit" title="Bit">bit</a> as a dot time, a Morse code sequence may be crudely represented a combination of the following five bit-strings: <ol><li>short mark, dot or dit (  ▄ ): '1'b</li> <li>longer mark, dash or dah (  ▄▄▄ ): '111'b</li> <li>intra-character gap (between the dits and dahs within a character): 0</li> <li>short gap (between letters): '000'b</li> <li>medium gap (between words): '0000000'b</li></ol> The marks and gaps alternate: Dits and dahs are always separated by one of the gaps, and that the gaps are always separated by a dit or a dah. A more efficient binary encoding uses only two-bits for each dit or dah element, with the 1 dit-length pause that must follow after each automatically included for every 2 bit code. One possible coding is by number value for the length of signal tone sent one could use '01'b for a dit and the automatic single-dit pause after it, and '11'b for a dah and the automatic single-dit following pause, and '00'b for the extra pause between letters (in effect, an end-of-letter mark). That leaves the code '10'b available for some other purpose, such as an escape character, or to more compactly represent the extra space between words (an end-of-word mark) instead of '00 00 00'b (only 6 dit lengths, since the 7th is automatically inserted as part of the prior dit or dah). Although the dit and inter-letter pauses work out to be the same, for any letter containing a dah, the two-bit encoding uses digital memory more compactly than the direct-conversion bit strings mentioned above. Including the letter-separating spaces, all International Morse letter codes pack into 12 bits or less (5 symbols), and most fit into 10 bits or less (4 symbols); most of the <a href="/wiki/Prosigns_for_Morse_code" title="Prosigns for Morse code">procedural signs</a> fit into 14 bits, with a few only needing 12 bits (5 symbols); and all digits require exactly 12 bits. For example, Morse G (  ▄▄▄ ▄▄▄ ▄  + 2 extra empty dits for "end of letter") would binary-encode as '11'b, '11'b, '01'b, '00'b; when packed it is '1111 0100'b = 'F4'x, which stores into only one <a href="/wiki/Byte" title="Byte">byte</a> (two <a href="/wiki/Nibble" title="Nibble">nibbles</a>) (as does every three-element code). The bit encoding for the longer method mentioned earlier the same letter would encode as '1110'b, '1110'b, '1000'b = '1110 1110 1000'b = 'EE8'x, or one-and-a-half bytes (three nibbles).

A dah is the length of 3 dits (with no gaps between), and spacings are specified in number of dit lengths. An unambiguous method of specifying the transmission speed is to specify the dit duration as, for example, 50 milliseconds. Specifying the dit 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 dit lengths. It is not immediately clear how a specific word rate determines the dit duration in milliseconds. Some method to standardize the transformation of a word rate to a dit duration is useful. A simple way to do this is to choose a dit 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 dit rate that would send the typical word 13 times in exactly one minute. The typical word thus determines the dit 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 dit units is 50 and a simple calculation shows that the dit length at 20 words per minute is 60 milliseconds. Using the word CODEX with 60 dit units, the dit length at 20 words per minute is 50 milliseconds. Because Morse code is usually sent by hand, it is unlikely that an operator could be that precise with the dit 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.<a href="#cite_note-US-CFR-Title-47-63">[57]</a>: §13.207(c), §13.209(d)  The <a href="/wiki/FCC" class="mw-redirect" title="FCC">FCC</a> specifies that a "word" is 5 characters long. 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.<a href="#cite_note-US-CFR-Title-47-63">[57]</a>: §13.203(b)  The word per minute rate would be close to the PARIS standard, and the code groups per minute would be close to the CODEX standard. 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 href="#cite_note-US-CFR-Title-47-63">[57]</a>: §97.503, 1996  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.<a href="#cite_note-FCC-radiotelegraph-33">[31]</a> Based upon a 50 dit duration standard word such as PARIS, the time for one dit duration or one unit can be computed by the formula: <dl><dd><math xmlns="http://www.w3.org/1998/Math/MathML" alttext="{\displaystyle ~T={\frac {\,1,200\,}{W}}~}"> <semantics> <mrow class="MJX-TeXAtom-ORD"> <mstyle displaystyle="true" scriptlevel="0"> <mtext> </mtext> <mi>T</mi> <mo>=</mo> <mrow class="MJX-TeXAtom-ORD"> <mfrac> <mrow> <mspace width="thinmathspace" /> <mn>1</mn> <mo>,</mo> <mn>200</mn> <mspace width="thinmathspace" /> </mrow> <mi>W</mi> </mfrac> </mrow> <mtext> </mtext> </mstyle> </mrow> <annotation encoding="application/x-tex">{\displaystyle ~T={\frac {\,1,200\,}{W}}~}</annotation> </semantics> </math><img src="https://wikimedia.org/api/rest_v1/media/math/render/svg/c22258e12ebe99e199a9426262140cdaad098d3b" class="mwe-math-fallback-image-inline mw-invert skin-invert" aria-hidden="true" style="vertical-align: -2.005ex; width:13.19ex; height:5.509ex;" alt="{\displaystyle ~T={\frac {\,1,200\,}{W}}~}"></dd></dl> where: T is the unit time, or dit duration in milliseconds, and W is the speed in <a href="/wiki/Words_per_minute" title="Words per minute">WPM</a>. <a href="/wiki/High-speed_telegraphy" title="High-speed telegraphy">High-speed telegraphy</a> contests are held; according to the <a href="/wiki/Guinness_Book_of_Records" class="mw-redirect" title="Guinness Book of Records">Guinness Book of Records</a> in June 2005 at the <a href="/wiki/International_Amateur_Radio_Union" title="International Amateur Radio Union">International Amateur Radio Union</a>'s 6th World Championship in High Speed Telegraphy in <a href="/wiki/Primorsko" title="Primorsko">Primorsko</a>, Bulgaria, Andrei Bindasov of <a href="/wiki/Belarus" title="Belarus">Belarus</a> transmitted 230 Morse code marks of mixed text in one minute.<a href="#cite_note-Guinness-records-Morse-64">[58]</a> <div class="mw-heading mw-heading3"><h3 id="Farnsworth_speed">Farnsworth speed</h3></div> 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 Farnsworth method is named for Donald R. "Russ" Farnsworth, also known by his <a href="/wiki/Call_sign" title="Call sign">call sign</a>, W6TTB. 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, invented in 1935 by the German engineer and former <a href="/wiki/Sturmabteilung" title="Sturmabteilung">stormtrooper</a> Ludwig Koch,<a href="#cite_note-65">[59]</a> which uses the full target speed from the outset but begins with just two characters. Once strings containing those two characters can be copied with 90% accuracy, an additional character is added, and so on until the full character set is mastered. 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 <a href="/wiki/W1AW" title="W1AW">W1AW</a>, the American Radio Relay League's headquarters station.<a href="#cite_note-66">[60]</a> As of 2015,<a class="external text" href="https://en.wikipedia.org/w/index.php?title=Morse_code&action=edit">[update]</a> the United States military taught Morse code as an 81-day self-paced course, having phased out more traditional classes.<a href="#cite_note-67">[61]</a> <div class="mw-heading mw-heading3"><h3 id="Mnemonics">Mnemonics</h3></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"><div role="note" class="hatnote navigation-not-searchable">Main article: <a href="/wiki/Morse_code_mnemonics" title="Morse code mnemonics">Morse code mnemonics</a></div> <figure class="mw-default-size mw-halign-right" typeof="mw:File/Thumb"><a href="/wiki/File:Morse_Code_Mnemonic_chart_from_Girl_Guides_handbook_1916.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/en/thumb/6/69/Morse_Code_Mnemonic_chart_from_Girl_Guides_handbook_1916.jpg/220px-Morse_Code_Mnemonic_chart_from_Girl_Guides_handbook_1916.jpg" decoding="async" width="220" height="157" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/en/thumb/6/69/Morse_Code_Mnemonic_chart_from_Girl_Guides_handbook_1916.jpg/330px-Morse_Code_Mnemonic_chart_from_Girl_Guides_handbook_1916.jpg 1.5x, //upload.wikimedia.org/wikipedia/en/thumb/6/69/Morse_Code_Mnemonic_chart_from_Girl_Guides_handbook_1916.jpg/440px-Morse_Code_Mnemonic_chart_from_Girl_Guides_handbook_1916.jpg 2x" data-file-width="932" data-file-height="667" /></a><figcaption><a href="/wiki/Scouting" title="Scouting">Scout</a> movement founder <a href="/wiki/Robert_Baden-Powell,_1st_Baron_Baden-Powell" title="Robert Baden-Powell, 1st Baron Baden-Powell">Baden-Powell's</a> mnemonic chart from 1918</figcaption></figure> Visual mnemonic charts have been devised over the ages. <a href="/wiki/Robert_Baden-Powell,_1st_Baron_Baden-Powell" title="Robert Baden-Powell, 1st Baron Baden-Powell">Baden-Powell</a> included one in the <a href="/wiki/Girl_Guides" title="Girl Guides">Girl Guides</a> handbook<a href="#cite_note-Baden-Powell-1938-68">[62]</a> in 1918.

The usual method has been to first transliterate the sounds represented by the International code and the four unique Gerke codes into the local alphabet, hence <a href="/wiki/Morse_code_for_non-Latin_alphabets" title="Morse code for non-Latin alphabets">Greek, Hebrew</a>, <a href="/wiki/Russian_Morse_code" title="Russian Morse code">Russian, and Ukrainian</a> Morse codes. If more codes are needed, one can either invent a new code or convert an otherwise unused code from either code set to the non-Latin letter. For example: <ul><li><a href="/wiki/%C3%91" title="Ñ">Ñ</a> in Spanish Morse is   ▄▄▄ ▄▄▄ ▄ ▄▄▄ ▄▄▄ , a language-specific code not used in either International or Gerke Morse.</li> <li>For the Greek letter <a href="/wiki/%CE%A8" class="mw-redirect" title="Ψ">Ψ</a>, <a href="/wiki/Morse_code_for_non-Latin_alphabets" title="Morse code for non-Latin alphabets">Greek Morse code</a> uses the International Morse code for <a href="/wiki/Q" title="Q">Q</a>,   ▄▄▄ ▄▄▄ ▄ ▄▄▄ , which has no corresponding letter in modern Greek; <a href="/wiki/%CE%A8" class="mw-redirect" title="Ψ">Ψ</a> and <a href="/wiki/Q" title="Q">Q</a> have no historical, phonetic, or shape relationship.</li></ul> For <a href="/wiki/Russian_language" title="Russian language">Russian</a> and Bulgarian, <a href="/wiki/Russian_Morse_code" title="Russian Morse code">Russian Morse code</a> is used to map the Cyrillic characters to four-element codes. Many of the characters are encoded the same as their latin-alphabet look-alikes or sound-alikes (A, O, E, I, T, M, N, R, K, etc.). The Bulgarian alphabet contains 30 characters, which exactly match all possible combinations of 1, 2, 3, and 4 dits and dahs (Russian Ы is used as Bulgarian Ь, Russian Ь is used as Bulgarian Ъ). Russian requires two more codes, for letters <a href="/wiki/%D0%AD" class="mw-redirect" title="Э">Э</a> and <a href="/wiki/%D0%AA" class="mw-redirect" title="Ъ">Ъ</a> which are each encoded with 5 elements. Non-<a href="/wiki/Alphabet" title="Alphabet">alphabetic</a> scripts require more radical adaption. Japanese Morse code (<a href="/wiki/Wabun_code" title="Wabun code">Wabun code</a>) has a separate encoding for <a href="/wiki/Kana" title="Kana">kana</a> script; although many of the codes are used for International Morse, the sounds they represent are mostly unrelated. The Japanese / <a href="/wiki/Wabun_code" title="Wabun code">Wabun</a> code includes special <a href="/wiki/Prosigns_for_Morse_code" title="Prosigns for Morse code">prosigns</a> for switching back-and-forth from International Morse:   ▄▄▄ ▄ ▄ ▄▄▄ ▄▄▄ ▄▄▄  signals a switch from International Morse to <a href="/wiki/Wabun_code" title="Wabun code">Wabun</a>, and   ▄ ▄ ▄ ▄▄▄ ▄  to return from <a href="/wiki/Wabun_code" title="Wabun code">Wabun</a> to International Morse.
