GNU Radio is a free & open-source software development toolkit that provides signal processing blocks to implement software radios. It can be used with readily-available low-cost external RF hardware to create software-defined radios, or without hardware in a simulation-like environment. It is widely used in hobbyist, academic and commercial environments to support both wireless communications research and real-world radio systems.

Universal Sofware Radio Peripheral (USRP)
- 2 x AD9862 codec: each 2 A/D 12 bit, 64 Megasamples/sec; 2 D/A, 14 bit, 128 Ms/sec
- FPGA: Altera Cyclone EP1C12, 64 MHz, 12,060 LEs, 239,616 RAM bits
- USB 2.0, Cypress FX2
- 4 x daughterboards for signal conditioning
Available from Ettus Research LLC, but design is open source.
Newer USRP2 has 100 MHz converters, much larger Xilinx FPGA
