SDR Software for using the badge

Just a quick check list of installations recommended before camp. Detailed descriptions below! Don't worry if you are not coming with a laptop, the badge will still be useful to you.


  • 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.
Debian based systems
  apt-get install hackrf gqrx-sdr gnuradio gr-osmosdr

NOTE: For Debian/Ubuntu Systems you qgrx will not work correctly, if you have the hackrf kernel module loaded. Additionally you will need some UDEV rules.

1. Create 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"

2. blacklist the hackrf module. If you don't do this / still have the module loaded 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. make sure you boot the hackrf-old, as gqrx somehow only recognized the device as a hackrf then (at least with gqrx from debian testing)

4. check with hackrf_info that everything works

5. launch gqrx, it should autoconfigure itself

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



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

Install GnuRadio

sudo port install gnuradio

You also want to install the OsmoSDR radio blocks for GnuRadio

sudo port install gr-osmosdr

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)

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: SDR for Noobs SDR for non-noobs

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)
