morse decoding with the Z80A - using the Elektor Z80A card, the Elekterminal and a CW signal forming circuit

morse decoding with the 280A elektor may 1983 including a program by P. von Berg (ON6XK) Spoken language is a code made up of sounds and it describes reality. Written language is a graphical coding of spoken language .. . and morse is an audible coding of written language. Not to mention written morse which is a graphical coding of an audible code .. . and so on. In short this is a mental feat which is left more and more to machines. We already have the necessary machines; now all we need is the software to drive them. That is what we have here, designed specifically for the Elektor Z80A CPU card. morse decoding with the Z80A using the Elektor Z80A card, the Elekterminal and a CW signal forming circuit In this issue we are presenting two CW decoding programs; one for the Junior Computer and other 6502 systems, and the other, described here, for Z80A sys- tems. We will refer to the other article for information on the nature of a morse signal, the difficulties posed by its automati...
