Abstract : The problem of translating and transcribing manual morse automatically was studied. The nature of the problem is discussed including the basic detection problem encountered with manual morse. An explanation of the theory of operation of the device follows with a block diagram and a short description of each block. The third section discusses the tests, evaluation and modifications including operation in the minimum signal to noise ratio and code speed tracking capability. Areas for further development are next considered which include an automatic recalibration scheme and the use of read only memories in the decoging section.
