With the advancement of electronics, fully automatic keyers that generated dots and dashes were eventually produced. Some of the earliest designs date from the 1940s, one even appeared in the April 1940 edition of QST, the magazine of the American Radio Relay League. Since then considerable developments have been made in terms of Morse keyer technology.The technology for these keyers has been further enhanced and most are now able to store strings of letters or pre-set messages. In this way for ham radio contests, or other forms of operation, frequently used messages can be stored and sent quickly and accurately.Nowadays, many ham radio transceivers include the electronic circuitry for the Morse keyer. All that is required is for the external contacts for the Morse paddle to be made to the...
