Morse code abbreviations

Morse Code is a way of sending messages in a very simple way. It uses a series of short and long sounds, or blips, to represent letters, numbers and other characters. Each sound has a different meaning, so only someone that knows Morse Code can understand the message. To make it easier to remember, each letter and number has a short abbreviation, called a "code", to represent it so it can be easily told to someone else.
