Abstract
A Morse code training tool and use method for learning how to copy and send Morse coded messages.
Claims8
A system for training Morse code copying and sending comprising:
- a microphone operative to convert received Morse code audio tones, as generated by a user, into analog electrical signals;
- an analog-to-digital converter operative to convert said analog electrical signals into equivalent-value digital signals preserving time-varying characteristics;
- a microcontroller comprising a central processing unit, read/write memory and input/output functional blocks;
- firmware memory comprising a stored training program;
- said training program operative to instruct said microcontroller to encode text sequences into time-varying Morse coded sequences;
- said training program operative to instruct said microcontroller to generate Morse code audio tones based on said time-varying Morse coded sequences;
- said training program operative to instruct said microcontroller to capture said Morse code audio tones generated by said user;
- said training program operative to instruct said microcontroller to convert said Morse code audio tones, generated by said user, into said time-varying Morse coded sequences;
- said training program operative to instruct said microcontroller to compare said time-varying Morse coded sequences converted into said Morse code audio tones previously sent by said system to those said Morse code audio tones subsequently sent by a user;
- said training program operative to instruct said microcontroller to determine if said Morse code audio tones sent by said system and those said Morse code audio tones sent by said user are essentially identical;
- a user-interface subsystem comprising operational controls and visual display operative to power up said system, to select said time-varying Morse coded sequences, and to initiate comparisons of said Morse code audio tones sent by said user to Morse code audio tones sent by said system;
- a storage subsystem operative to store training-segment contents;
- a digital-to-analog converter operative to convert digitized Morse code sequences into equivalent Morse code analog signals;
- and
- headphones operative to convert said time-varying Morse coded sequences into audible sounds.
