Morse code mnemonics to remember Morse codes lies in remembering words that begin with each appropriate letter and has so called long vowel (i.e. á é í ó ú ý) for every dash and short vowel (a e i o u y) for every dot. Additionally, some other theme-related sets of words have been thought out as Czech folklore. In Indonesia, one mnemonics commonly taught in scouting method to remember Morse codes lies in remembering words that begin with each appropriate letter and substituting the o vowel for every dash and other vowels (a, i, u, and e) for every dot. Morse code
Morse code and most versatile methods of telecommunication. The most common distress signal is SOS – three dots, three dashes, and three dots – internationally recognized by treaty. Beginning in 1836, the American artist Samuel F. B. Morse, the American physicist Joseph Henry, and 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. Around 1837, Morse, therefore, developed an early forerunner to the
