The Elektor SDR Hands-On-Kit is a low cost (€49.46) SDR learning package that makes use of the Elektor SDR Arduino shield which turns an Arduino microcontroller board into a 150 kHz to 30 MHz capable SDR receiver. It also comes with a book that teaches several basic SDR concepts.
Over on YouTube TechMinds has recently uploaded a video where he unboxes, constructs, and tests the kit using the free G8JCFSDR SDR software. TechMinds also notes that this SDR Shield can also transmit with 10mW of power, and that there is a tutorial included in the book that shows how to use the shield as a simple WSPR transmitter.
Elektor SDRShield - Hands-on Software Defined Radio Kit
Over on YouTube, Elektor have uploaded an overview of their Elektor SDR Hands-on kit. The €49.46 kit is an Arduino shield, that turns an Arduino microcontroller board into a 150 kHz to 30 MHz capable SDR receiver. It is based on the G8JCFSDR, which is an RF front end downconverter that allows a PC soundcard to be used as an SDR analog to digital converter.
To compliment the SDR is a book that goes over introductory topics such as shortwave reception, explains signal to noise ratio and interference, different types of antennas, software, digital modes, SDR measurements, receiving and finally WSPR and QRP transmissions. Overall this looks like a good kit for learning about the technical basics of SDRs.
