The new Elektor SDR Shield for Arduino – Travelling the waves

How to use SDR software in combination with the new Elektor SDR Shield to get the best listening results. A Software Defined Radio is a universal tool in RF technology circles, one that can also be put to use for making measurements. The characteristics of the receiver are defined in software, which now gives us the opportunity to use an Arduino Shield as a front-end. This Arduino shield is a remake of our famous SDR project published in 2007. Listen to all radio frequencies from 150kHz up to 30MHz. Technical Characteristics • Supply voltage: 5 V and 3.3 V as for Arduino • Frequency range: 150 kHz up to 30 MHz • Sensitivity: 1 μV • Total amplification: 40 dB • Maximum antenna signal level: 10 mV • Dynamic range: 80 dB
