Start a Terminal

Execute

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install git-core git cmake libusb-1.0-0-dev build-essential
git clone git://git.osmocom.org/rtl-sdr.git
cd rtl-sdr
mkdir build
cd build
cmake ../ -DINSTALL_UDEV_RULES=ON

sudo make install
sudo ldconfig

Connect antenna, cables (without band-pass filter), Install dongle

cd ~
sudo cp ./rtl-sdr/rtl-sdr.rules /etc/udev/rules.d/
sudo printf 'blacklist dvb_usb_rtl28xxu\nblacklist rtl2832\nblacklist rtl2830' > /etc/modprobe.d/nortl.conf
sudo reboot

Calibrate:

Download, compile and install the Kalibrate programm

mkdir ~/kal
cd ~/kal
sudo apt-get install libtool autoconf automake libfftw3-dev
git clone https://github.com/asdil12/kalibrate-rtl.git
cd kalibrate-rtl
git checkout arm_memory
./bootstrap
./configure
make
sudo make install

Calibrate:

kal -s GSM900 -d 0 -g 40

You'll get something like:

Use the most powerful channel (69 in the example above) for calibration

kal -c <channel> -d 0 -g 40

You'll get something like:

Note the "average absolute error" number. If you have it around 0, everything's fine.
If not, you may need to change the frequency when you start `dump1090`.

Build dump1090

cd ~
git clone git://github.com/MalcolmRobb/dump1090.git
cd dump1090
sudo apt-get install pkg-config
make

Try it:

./dump1090 --interactive --net

You should be getting output like:

FlightAware Band-Pass filter is highly recommended, it drastically increases the number of messages.
