Over on his blog Michael Carden has produced a tutorial showing us how to use SDR-J on the Raspberry Pi 3 for receiving Digital Audio Broadcast (DAB) radio. DAB is a type of digital broadcast radio used in several countries outside of the USA for general broadcast radio programs. It usually provides clearer digital audio compared to FM broadcast.
His post starts from scratch, showing how to create a Raspberry Pi image file and configure the Pi, then shows how to install and use SDR-J.
SDR-J is also available for Windows and is compatible with the RTL-SDR and other radios such as the Airspy and SDRplay.
