"The Art of SDR" is about understanding, building and using SDRs to enjoy listening to radio stations near and afar.

SDR is software defined radio which replaces traditional analog radio circuits with digital circuits and computer software. The software provides flexibility to change the functions of the software defined radio. The RTL-SDR V3 used with the Raspberry Pi 4 Model B computer provides a low cost flexible SDR implementation that provides hours of radio listening fun.

In the funture other SDRs and computers will be used in the videos.
