In May 2007 Elektor published a simple Software Defined Radio (SDR) project that became an instant hit. Now, almost ten years later, a redesign has been launched. New, fresh components have been placed on an Arduino add-on board to create the new Elektor SDR shield.

The new SDR board was created by Burkhard Kainka, the designer who also did the first SDR project. The antenna preselector of the original board has been removed while the CY27EE16 programmable oscillator was replaced by the Si5351 from Silicon Labs. The Arduino board takes over the functions of the FT232R USB interface in the original design.
