- Gqrx binary package for Mac OS X, experimental build and known to have problems. Built on Mac OS X 10.11 but might work up to 10.15 (SourceForge) On Mac you can also install the latest version through Macports and probably also other package managers like Homebrew. I can only provide very limited support for Mac OS X.
- Gqrx is a software defined radio receiver powered by GNU Radio and the Qt GUI toolkit. It can process I/Q data from many types of input devices, including Funcube Dongle Pro/Pro+, rtl- sdr, HackRF, and Universal Software Radio Peripheral (USRP) devices.
This video explains how the RTL-SDR dongle works. I will show you how to open the RTL-SDR dongle and show you (very detailed) what it inside this particular. Gqrx Package Description. Gqrx is a software defined radio receiver powered by the GNU Radio SDR framework and the Qt graphical toolkit. Gqrx supports many of the SDR hardware available, including Funcube Dongles, rtl-sdr, HackRF and USRP devices. See supported devices for a complete list. Gqrx is free and hacker friendly software.

Ubuntu Packages
Starting with this release, we have a new PPA that contains only Gqrx binaries and uses MyriadRF PPAs for GNU Radio and SDR driver packages. I realize this is inconvenient for existing PPA users; however, this offloads some of the packaging work from me and will ensure more up to date GNU Radio packages for Ubuntu users in the future.
Please make sure you have the previous PPA disabled and old, obsolete packages removed before using the new PPA as instructed on the Ubuntu Install page. Feel free to contact us if you need help with the PPA transition.
Mac OS X binaries
Gqrx Mac Brew
As always, there is an up to date Gqrx package in Macports. There is now also an app bundle available from GitHub or SourceForge. The bundle was built on Mac OS X El Capitan and contains all required third part libraries, as well as the command line utilities that come with the Airspy, RTL-SDR, Hackrf and Bladerf driver libraries. See the included README for details.
Installing from source
The source code can be downloaded from GitHub or SourceForge. Starting with this release, gqrx can also be compiled using cmake, see the README file for details. Building with qmake is still available and will not disappear any time soon, so feel free to use either method.
Have fun!
