Concerning Full Raspberry Pi OS software installed on a single Raspberry Pi image, we’re encouraging high schools to use this installation document. https://docs.google.com/document/d/1hfS7cRx3emlZz0sTs583zN8o-35nKtIej6BYMKCJLXY/edit?usp=sharing
The document includes the links to the OS and hardware to purchase. Unfortunately this is a 3.7.13.4 Gnuradio release, as we’ve not had the strength to get the SDRPlay software support working for newer gnuradio Releases.
