International Morse code encodes the 26 basic Latin letters A to Z, one accented Latin letter (É), the Arabic numerals, and a small set of punctuation and procedural signals . There is no distinction between upper and lower case letters. Each Morse code symbol is formed by a sequence of dits and dahs.
American Morse code. American Morse Code — also known as Railroad Morse—is the latter-day name for the original version of the Morse Code developed in the mid-1840s, by Samuel Morse and Alfred Vail for their electric telegraph. The "American" qualifier was added because, after most of the rest of the world adopted " International Morse Code ...
In Czech, the mnemonic device to remember letters in Morse code lies in remembering words or short phrases that begin with each appropriate letter and have a long vowel (i.e. á é í ó ú ý) for every dash and a short vowel (a e i o u y) for every dot. Additionally, some other sets of words with a particular theme have been thought up in ...
A telegraph code is one of the character encodings used to transmit information by telegraphy. Morse code is the best-known such code. Telegraphy usually refers to the electrical telegraph, but telegraph systems using the optical telegraph were in use before that. A code consists of a number of code points, each corresponding to a letter of the ...
Even though represented as strings of letters, prosigns are rendered without the intercharacter commas or pauses that would occur between the letters shown, if the representation were (mistakenly) sent as a sequence of letters: In printed material describing their meaning and use, prosigns are shown either as a sequence of dots and dashes for the sound of a telegraph, or by an overlined ...
Letter beacon. Signal of letter beacon D on 5137.5 kHz. Letter beacons are radio transmissions of uncertain origin and unknown purpose, consisting of only a single repeating Morse code letter. They have been classified into a number of groups according to transmission code and frequency, and it is supposed that the source for most of them is ...
Friedrich Clemens Gerke (22 January 1801 – 21 May 1888) was a German writer, journalist, musician and pioneer of telegraphy who revised the Morse code in 1848. It is Gerke's version of the original (American) Morse code now known as the International Morse code and standardized by the ITU (International Telecommunication Union) which is used ...
A telegraph key or Morse key is a specialized electrical switch used by a trained operator to transmit text messages in Morse code in a telegraphy system. Keys are used in all forms of electrical telegraph systems, including landline (also called wire) telegraphy and radio (also called wireless) telegraphy. An operator uses the telegraph key to ...
