Morse Code

Morse code encodes text characters as sequences of dots and dashes, and it is still widely used in telecommunication. Ham operators lean on morse code because a faint signal that is unreadable by voice can still get through in dots and dashes, which makes it a useful backup when other systems fail. The chart below shows the morse code for every letter and number. If you are working toward your license, the ham radio license exam prep class covers how operators use it on the air.
