The Morse Code
In some ways the general perception is correct that Morse code has become anachronistic. But when an emergency occurs and lots of equipment is broken, there is no other means of communications that works with the simplest radios, gets through interference better, and uses less radio bandwidth (allowing more communications to occur simultaneously) than Morse Code. In short, there may be nothing else that will work in some emergencies.
Character Representation
| International Morse Code Characters | ||||
| Letter | Letter | Letter | Numeral | |
| A = .- | K = -.- | U = ..- | 0 = ----- | |
| B = -... | L = .-.. | V = ...- | 1 = .---- | |
| C = -.-. | M = -- | W = .-- | 2 = ..--- | |
| D = -.. | N = -. | X = -..- | 3 = ...-- | |
| E = . | O = --- | Y = -.-- | 4 = ....- | |
| F = ..-. | P = .--. | Z = --.. | 5 = ..... | |
| G = --. | Q = --.- | Fullstop = .-.-.- | 6 = -.... | |
| H = ... | R = .-. | Slash = -..-. | 7 = --... | |
| I = .. | S = ... | Comma = --..-- | 8 = ---.. | |
| J = .--- | T = - | Query = ..--.. | 9 = ----. | |
Notes
- A dash is equal to three dots
- The space between parts of the same letter is equal to one dot
- The space between two letters is equal to three dots
- The space between two words is equal tofive dots
How do the Morse Code Characters Sound?
The visual references of dots and dashes can be harmful to the process of learning the code. Rather than having to un-learn them later, start by trying to recognize the sounds of the characters.
The short tones, commonly represented as dots, should be said as the word "dit", which sounds close to how it would on the air. Likewise, the long tones or dashes should be said as "dah", which takes longer to say than "dit" and sounds more like it would on the air. When several tones are strung together to make a character, the 't' in "dit" and the 'h' in "dah" are left off, again to help represent the sound better.
