SDR Software for using the badge


GNU Radio (Linux/Mac/Windows)

It's highly recommended to build GNU Radio from source to use the most up-to-date version: Installation

There were two GNU Radio workshops at Easterhegg 2015:

gnuradio-companion is the full-fledged signal processing application.

osmocom_fft is a nice little graphical tool for quick signal checks.

Gqrx SDR (Linux/Mac)

SDR# (Windows)

RF Analyzer (Android)

installation details


  • GNU Radio - Powerful suit for signal processing. Also contains 'gnuradio-companion', a GUI for designing the the processing blocks.
  • Gqrx SDR - Easy display of signal strengths/waterfall etc. with basic filtering and demodulation support.
  • Baudline (not in the Debian package repository) - Another signal visualizer.
  • inspectrum - Similar to baudline, but OSS.

Debian based systems

NOTE: Current versions of gqrx-sdr and gr-osmosdr in Ubuntu 14.04 are known to cause issues with the rad1o. (hackrf_info not detecting the badge, error loading libosmosdr etc.) The original hackrf wiki has a PPA with updated versions.

1. Install software:

  apt-get install hackrf gqrx-sdr gnuradio gr-osmosdr

2. Make sure the hackrf kernel module is not loaded. If you don't do this, you'll get a -1000 error from hackrf_info

$ sudo rmmod hackrf
$ sudo vim /etc/modprobe.d/blacklist.conf
# module blacklisted for radi1o / gqrx usage
blacklist hackrf

3. Additionally you will need some UDEV rules. Replace YOURUSER with your username (whoami)

$ sudo vim /etc/udev/rules.d/51-rad1o.rules
SUBSYSTEM=="usb", ATTR{idVendor}=="1d50", ATTR{idProduct}=="cc15", MODE="0600", OWNER="YOURUSER", GROUP="YOURUSER"
SUBSYSTEM=="usb", ATTR{idVendor}=="1d50", ATTR{idProduct}=="6089", MODE="0600", OWNER="YOURUSER", GROUP="YOURUSER"

4. make sure you boot the hackrf-old on the rad1o, as gqrx somehow only recognized the device as a hackrf then (at least with gqrx from debian testing)

5. check with hackrf_info that everything works

6. launch gqrx, it should autoconfigure itself


  pacman -S gqrx python2 python2-lxml python2-cheetah # pulls hackrf and gnuradio automatically in

Gentoo Linux

Versions known to work:

net-wireless/gnuradio-3.7.7.x net-wireless/gr-osmosdr-1.4_x net-wireless/gqrx-2.3.x

Make sure the 'hackrf' useflag is enabled where available.

If you have the 'hackrf' kernel module compiled, prevent it from loading by adding

  blacklist hackrf

to your /etc/modprobe.d/blacklist.conf. (update your modprobe config with 'depmod -a')


1. Install software:

$ sudo dnf install gnuradio gnuradio-doc gnuradio-examples gqrx hackrf hackrf-doc gr-osmosdr gr-air-modes
Fedora 24 also needs hackrf-static.

2. boot into HKRF-OLD on the rad1o (for now, hopefully soon in HACKRF mode)

3. check if it's detected with hackrf_info

$ hackrf_info
Found HackRF board.
Board ID Number: 3 (Unknown Board ID)
Firmware Version: [...]
Part ID Number: [...]
Serial Number: [...]

4. run gqrx, accepting the default of hackrf unknown device. Gqrx SDR Supported hardware

$ gqrx

5. if you get results in gqrx, move on to osmocom_fft, keeping in mind that the built-in antenna is tuned to 2.5GHz

$ osmocom_fft

6. now you are sure the rad1o speaks to your Fedora box and you can move on to GNU Radio

$ gnuradio-companion

To use the rad1o, search for blocks with osmocom in the name in GNU Radio.

You may want to check out the files in /usr/share/gnuradio/examples/



Follow these instructions to install Gnuradio-Suite on your Mac: Prerequisites:

Install GnuRadio with MacPorts:

sudo port install gnuradio

You also want to install the OsmoSDR radio blocks for GnuRadio

sudo port install gr-osmosdr

To install GnuRadio with HomeBrew, you can follow this guide.

Start GnuRadio in the terminal with



The original RF Analyzer doesn't work with rad1o and it's author hasn't merged our pull request yet. So you need our patched version (see below)

RF Analyzer (Android)

Patched version with rad1o support:

Requires an OTG cable or adapter and an OTG capable mobile (e.g. Jolla and Nexus 4 are not)
