Running an SDRplay RSP2 on a Raspberry Pi 3 with CubicSDR

Over on YouTube user Kevin Loughin has uploaded a video demonstrating his SDRplay RSP2 running on a Raspberry Pi 3. The software he uses is CubicSDR which is a multiplatform program that is similar to software like SDRUno, SDR#, SDR-Console, HDSDR etc. The video shows CubicSDR running, but the interface is quite slow and laggy, although the audio is at least not choppy.

In a previous post we showed one of Kevin’s earlier videos where he does a tutorial and some scripts that help to actually set up the SDRplay drivers and CubicSDR in Linux. In the new video he first goes over a specific hack that needs to be done in Raspbian to fix the PulseAudio server. Then he explains that you can run the Linux build script mentioned in his previous tutorial video and it should work on the Raspberry Pi 3 just fine. Finally he mentions that CubicSDR and the SDRplay use a high amount of CPU processing on the pi3 so some sort of cooling mechanism is required or the pi3 may throttle down its CPU.
