My second Raspberry Pi and a huge performance boost over the second iteration! I'm using this as a mobile SDR (quirky police scanner) with the GQRX software, but it gets very hot. So I ordered a custom heatsink/fan system to solve the temperature issues and it works really well! All in all a great calculator! If you add extra fans to them, you'll need to make sure you buy a power supply with some juice. I recommend one for 2.5 or 3.0 amps.
