- 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 In other howtos theres either huge amount of text or it's forward you to read a bunch of outdated manuals.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!
This is absolutely just awesome!! Thank you very much for sharing!!
Glad you enjoyed it!
Thank you!
Thanks you for this!
Sir I want to capture Dish TV signal which is 950MHz to 2150MHz ,,, using Hack RF one and gnu radio,,, can you please suggest me some article or source about this?
Hi, I want to learn Software define radio completely from scratch. which board shall i buy to start with. Should be like DIY. Based on this I should be able to make by board. Please suggest.
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.
@@ElektorTV Nice to hear.
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
a frequency block doesnt open for me.data was input as suggested.do i need to have a setting to have the box open?
i figured it out.helps if i have the rtl sdr drivers installed so the software can find the usb dongle.on to the next step :D
How is your signal so smooth? I followed what you did, and mine is incredibly noisy
Maybe try a better antenna or a stronger station or both?
would this build reach 1.6Ghz?
