ABSTRACT:
An extensive morse code processing system includes a microprocessor unit, a transmitter processing unit, a receiver processing unit, a display unit, a keyboard unit, and a radio unit. Whenever a data key on the keyboard is pressed, the ASCII code of the pressed key is received by the microprocessor unit and is converted into a binary line code. The line code is processed by the transmitter unit and is then transmitted as morse code signals by the radio unit. Morse code signals received by the radio unit are converted by the receiver unit into the corresponding binary line code. The line code from the receiver unit serves as input to the microprocessor unit which converts the line code into standard ASCII. The microprocessor then actuates the display unit to display the received characters. Exchange of data between the microprocessor unit and a a computer is also possible through an RS-232 interface adapter interconnecting the computer and the microprocessor unit.
