Andrew Back G7JKB writes in Design Spark about using the Raspberry Pi 3, he is very adamant about this technology, his long journey to mastery started with the alluring Teardrop Flags at a technology trade show some years ago.

The LimeSDR board was only formally announced in February 2016 at the Mobile World Congress. Developed by Lime Microsystems in Guildford, Surrey and featuring their latest Field programmable RF (FPRF) transceiver, the LMS7002M, the SoDeRa is capable of supporting just about any wireless standard that operates between 100 kHz and 3.8 GHz. As if this wasn’t enough, it’s also dual channel — MIMO — with two each fully independent transmit and receive channels.

The board also includes an Altera Cyclone IV FPGA, enabling high throughput processing to be carried out in hardware, between the transceiver and FX3 USB 3.0 controller.
