Gqrx 2.2.0 released

After nearly one year of development since the last official release, we are now finally ready with Gqrx 2.2. Amongst the new features and bug fixes, this release brings support for the HackRF Jawbreaker and the Funcube Dongle Pro+. See supported hardware for a complete list of devices that are known to work with Gqrx.

Gqrx on shortwaves with Funcube Dongle Pro+

I have made a video recording of my first tests using Gqrx and the Funcube Dongle Pro+.

One of the biggest challenges with Gqrx has always been installation difficulties caused by the endless list of dependencies. To address this issue we are now officially packaging Gqrx for Ubuntu Linux and for Mac OS X, both distributions including all the dependencies that are not commonly available for that platform. In the case of Ubuntu Linux this has resulted in a complete GNU Radio package with the full SDK, including awesome tools such as the gnuradio-companion.

The app bundle for Mac OS X does not contain the full GNU Radio SDK; however, it does include various command line utilities that come with the hardware driver packages (rtl_test, hackrf_info, uhd_find_devices, etc).

Note that Ubuntu packages are available through two different channels:

  1. gqrx/releases containing official releases such as 2.2.0
  2. gqrx/snapshots containing development snapshots made a few times per month

Although it is probably possible to subscribe to both channels there is probably no reason to do so. All packages in gqrx/releases are also made available through gqrx/snapshots.

A list of changes since the previous releases is available in the news.txt file.

Head on to download page and get gqrx 2.2 now!

See Github for a list of known bugs. Feel free to report any new ones that you may encounter.

    Great news! I was waiting for the FCDPro+ support both in Gqrx as in the GNU Radio Companion Tool. Thanks for your work Alexandru!

    The package installed perfectly on my Ubuntu 12.04. The “gnuradio” package should be a dependency, otherwise gqrx will not run because of missing libraries.

    Finally a good and easy solution to install a SDR on Linux! Do you have any plans to implement a small rig control feature for using gqrx as a pan adapter? Only sync the frequency between a radiogqrx, nothing special? Most protocols are very simple …

    Thanks for your work!

    • Thanks for the feedback. I replied to your bug report and feature request on github. Here I can give a few mkore details about what I meant with the remote control. Gnuradio provides a framework for accessing parameters over the network. I plan taking advantage of this and separate the DSP processing and the user interface from each other. In practice, this will also allow third party applications to access the parameters in gqrx. This can be frequency, mode, gains, etc.

    Thanks for the Gqrx app.Works a treat on Ubuntu 12.04 with a RTL2832/R820T and external antenna mod.I’m well surprised on its sensitivity…

    I just wanted to say thank you for Gqrx SDR! I was trying to learn SDR using strictly GNURadio on Ubuntu 14.04 with a RTL2838 DVB-T…for a beginner, lets just say GNURadio is a bit intense. Gqrx SDR has definitely allowed me to gain a whole new understanding on SDR! Thanks again!! Is there a link somewhere for donations?

    • Hi Marcus,

      Thanks for the feedback. GNU Radio is a development framework while gqrx is an application that uses GNU Radio. For a user gqrx might be better but if you want to make your own SDRs then GNU Radio is a great tool.

      There is no donation option for gqrx. I do this as a hobby and have everything I need now. If you want, you can donate the amount to another project like linux or Wikipedia :-)

  • I have been screwing with GNURadio for 2 years now, and I am not a Linux newbie by ANY stretch of the imagination. I hated it. I despised it. I cursed. I bloated my PC with unrelated garbage trying to get it working, and trashed it so bad at one point I had to re-image. Finally gave up an resorted to using my Winblows machine… Until I found GQRX! Damn – wish I had found this 2 years ago… Anyway, the only issue I have is sensitivity. There seems to be a preset in the default initialization file for this (set at 0.5) but changing it does not seem to do anything. I have two different dongles, both work with GQRX and both work on SDR Radio in Winblows. The SDR Radio picks up great when I crank up the gain, but I don’t have the same option with GQRX. Maybe I am missing something. I will keep working on it – but at least the software works!

    • Hi Andrew,
      There is a gain slider on the “Input controls” tab. It’s values are in dB so I’m not sure where the 0.5 default comes from.

      • Hmm. Saw the slider, but it did not seem to do much for the sensitivity. I am looking into this as we speak. Thanks.

      • Thanks. I had to completely remove and reinstall the software and some dependencies. All works great now, and the input gain slider actually works. For some reason when I first installed it the slider would go up and down, but the gain would not change. Really odd, but I documented my fix and posted it you the Google Group.
