An Open Source SDR radio from 70Mhz to 6 GHz ...

The amazing SDR projects keep popping up!

How about this one: "The FreeSRP"

Receive and Transmit at the Same Time, yes full-duplex.. ( with a maximum output power of 50 mW @ 2.4 GHz)

This FPGA based board has a USB 3.0 port, can be used with GNU-radio under Ubuntu Linux and has a bandwidth of 61.44 MHz

It's a bit more expensive than the "HACK-RF ONE" board from one of my earlier posts, however the Hack-RF is a half-duplex SDR,
and this FreeSRP is using the powerfull Xilinx Artix 7 FPGA whereas the Hack-RF One board is using a CPLD.
