'''GNU Radio''' is the most widely used and supported software package used with [[Software Defined Radio (SDR)]]. It is extremely powerful and primarily aimed at research into transmitting and receiving specialised signal types. For this reason it is quite complex and has a somewhat steep learning curve.<br />
<br />
The GNU Radio suite is composed of a number of ''blocks'', each performing a specialised task (such as receiving data from an SDR device or demodulating a particular transmission mode.) By combining these blocks together into a ''flow graph'', a full demodulator/decoder can be built (starting from the radio device all the way to either audio output or displaying decoded digital data.)<br />
<br />
The flow graphs are built in the Python programming language, however it is not necessary to know any Python to create them. GNU Radio includes a program called <tt>gnuradio-companion</tt> which provides a neat graphical interface allowing Python flow graphs to be built by simply dragging boxes around on the screen.</div>Malvineous
