The software comes from PA3FWM and there is a binary for raspberry pie computers. The binary can run on any ARM CPU. I purchased a Odroid U3 which has a lot more CPU power. The picture shows the Odroid as well as the rtlsdr connected and a wifi stick used for connecting to my network. Running the WebSDR with 1MHz bandwith gives about 50% CPU load.<\/p>\n<p>The board runs Lubuntu 14.04.2.
