Over on YouTube, Rob from the Frugal Radio channel has uploaded a video showing that you don't need to shell out thousands for a capable PC to run your SDR. Robs finds five second-hand Dell Optiplex 9020 PCs advertised for just $25 each, and shows how each PC is powerful enough to run multiple SDR decoders at once, and run three monitors.

He notes that these PCs are a bargain as they come with a 4th gen Intel i5, 8GB RAM, and a 256 GB SSD. And they even come with Windows 10 Professional pre-installed.

Later in the video Rob shows what each of his $25 PCs is doing. He shows how PC1 decodes five digital trunk systems with RTL-SDRs and runs SDR++ with an Airspy. And how PC2 decodes P25 trunk systems and runs the PDW pager decoder.

Rob notes that deals on these second-hand Dell Optiplex 9020 PCs are easy to find on eBay as these are common ex-corporate PCs.
