With the GT software alone operating on an overclocked Raspberry Pi (1GHz), we recently achieved a really good result after some software optimization. It is no longer necessary to use the rtl_fm program. We now have even more potent boards thanks to the BananaPi and Raspberry Pi 2. It would be intriguing to observe the maximum capacity that their multi-core CPUs can offer.
Nice! Testing the BananaPi and Raspberry Pi 2's multi-core CPUs could unlock even more potential for your project. Have you started benchmarking them yet?
