Abstract:

A Morse code tutoring system: a computer with an appropriate program and a code practice oscillator interfacing to it. In one mode of operation, the operator uses a straight key to produce code in the oscillator which is monitored by the computer, and analyzed for quantitative elements of his "amateur accent", that is, those characteristic of his code that make it harder for another person to decode. In another mode, the computer generates code which is output by the oscillator, and the operator decodes it and feeds back to the computer the decoded message. In subsequent lessons, the code generated is enriched in those characters that he fed back erroneously.
