SDT21 simple digital QRPp transceiver

simple “digital” monoband transceiver SDT21 The goal of this project was the development of a simple to build CW monoband transceiver based on the direct superheterodyne principle with crystal control a la “PIXIE” or “Rockmite”, but with much better technical data. To minimize the circuit effort, the concept should be as highly integrated as possible…
