Software Defined Radio, also known as #SDR, is about modulating and demodulating radio signals in software. Instead of having special electronic circuitry to do this, like a mixer or demodulator, SDR uses software. Of course, there is some hardware involved in turning analog signals into digital and vice versa, but that is all you need. This video explains how to build a software-defined FM radio receiver with a HackRF One input device and GNU Radio Companion for the software.

Thank you very much. It's a perfect into for newbies. In other howtos theres either huge amount of text or it's forward you to read a bunch of outdated manuals. Again - thanks!

Cool! But - how many objects are there? How long will it take to do a demoldulation of a Wifi or DSL signal? Oh my god.... cool stuff on this world today

This is fantastic! Can Gnu Radio build some kind of stand alone program, after then you are done with all tweakings?

The output of GRC is a Python script. In the "Options" block you can set the "Generate Options" to "No GUI". If your flow graph does not have a GUI (sliders, windows, etc.) it will create a headless script that can be executed in another way like calling it from another process or so.
