Elektor SDR Shield 2.0 (1)
About two years have passed since the launch of the Elektor SDR Shield for creating a shortwave SDR using the Arduino . Plentiful positive feedback and countless experiments have aroused the desire to provide greater connectivity onboard. SDR Shield 2.0 is now the basis for far more than simply a receiver. Applications range from a signal generator through shortwave transmitters all the way to forming a complete shortwave transceiver.First steps with G8JCFSDR As not all readers will be familiar with the original SDR Shield, we ought to describe its beginnings here briefly.
