SDRplay have now made available a Raspberry Pi3 SD Card image which can be downloaded to give full local and remote receiver functionality on Linux, building on the work done by others (e.g. SoapySDR, SoapyRemote and Cubic SDR developers. Their frequency range has been extended to cover from 1 kHz up to 2 GHz. Popular with Radio Amateurs, the SDRplay family of Radio Spectrum Processors provide Software Defined Radio functionality and a level of radio receiver performance which a few years ago would have cost 1000s of Dollars. This is where the modern Software Defined Radio connected to a versatile computing platform, ticks most of the 'smart' boxes. I say 'smart' meaning 'smart' in their location (demanding remote access and or portability) and 'smart' in terms of controlling signal selection, recording techniques and in the way they enable post processing of, and access to, the resulting information. This SDR project demonstrates what’s achievable, in this case a multi-purpose receiver covering all bands from 150 kHz to 30 MHz. SD (software-defined) radio receivers use a bare minimum of hardware, relying instead on their software capabilities. But if you have an interest in collecting data which no-one else has thought to collect, and if that data can be collected from radio reception at an antenna, then smart receivers are what you may need. It’s been optimised for receiving DRM and AM broadcasts but is also suitable for listening in to the world of amateur transmissions.
