Click anywhere outside the cell to get the text in dots and dashes code. How do I translate Morse code? Write the text you want to encode in the Input cell.

See also our Documentation chapter to get the possibility to code and decode the language programmatically. It works from any browser and on any operating system.
You will also be able to listen to the audio. You get the result right away after entering the content you need to convert. The app here is what you need for dealing with such an issue. So if you want to translate to Morse or back quickly you may need some software. The main drawback of this coding is that it is pretty hard to memorize all the dots and dashes combinations. Learning the code is mandatory for avia dispatchers and in the navy. For broadcasting and receiving it, only the simplest devices are needed, so it can be used in situations when all the other ways to communicate will fall. The biggest benefit is that this code is reliable. You may think that it is outdated but there are still a few spheres where this alphabet is used. The Morse alphabet is counted as the first known digital way to transfer data. Morse code is the way to encrypt alphabet symbols by using short and long signals (dots and dashes) and pauses. 7 * Input ' Length ) - Upper Capacity First, Last : Natural := 0 Char_code : Codings begin for I in Cap_String ' Range loop if Is_In ( Cap_String ( I ), Morse_charset ) then First := Last + 1 if Cap_String ( I ) = ' ' then Result ( First ) := ' ' Last := Last + 1 else Char_code := Table ( Reschars ( Cap_String ( I ))) Last := First + Char_code.
