Signalling
Different forms of signalling were used during WW1 & WW2
Morse Code
Morse code is a type of code used to send messages via sound or visual signals. It uses the ABC alphabet, with each letter represented by a different sequence of long and short sound or visual signals called dots and dashes – or “dits an dahs”.
A radio machine was frequently used to send this signal of “dits an dahs” over long distances, but if you can’t use a sound signal, you could use lights. Ships often signal to each other in “Maritime Morse”.
