In addition to the listening to the podcast and watching the video, you might want to take a look at the article, “Essential Pi: Tips for Getting the Most Out of Your Raspberry Pi” from Electronic Design.

All in all, this sounds like just what I need to get GNU Radio to run well on the Raspberry Pi. In addition to talking about the software, Jason describes some hardware hacks he’s made, like using a solid-state drive (SSD) and overclocking the processor. In the meantime, I ran across this video by Jason: This sounded like just what I needed, and made a note to explore this further. This keeps your pi as lean and mean as possible. It allows you to choose the applications you want to install and skip the ones you don’t need. Rather than downloading a pre-built image where you have no choices in the build, Build-a- Pi gives you complete control over the build. According to the github page,īuild-a-Pi will allow you to get up and running fast with a Raspberry Pi for ham radio.
