Software Defined Radio or SDR is a radio technique that relies on software to do most of the hard radio work. In a traditional radio electronic circuitry is used to modulate or demodulate a high-frequency carrier signal to add or extract the information from it. SDR does all this in software.

Get Going with the Elektor SDR Hands-on Kit

The Arduino-compatible SDR shield contained in the Elektor SDR Hands-on Kit is an SDR front-end that can receive and transmit radio signals up to 30 MHz. The SDR Hands-on Book shows you how to use it to receive for instance Morse signals, shortwave radio stations, single sideband stations and digital signals, but also how to build a QRP transceiver or how to use it in an electronics lab as a measurement tool.

The kit is presented in more detail in this video:
