Persiapan
Buat directory
mkdir /usr/local/src/SDR cd /usr/local/src/SDR
Instalasi paket pendukung
sudo apt-get install cmake swig libcppunit-dev python-cheetah doxygen \ libboost-all-dev python-sphinx libfftw3-dev python-numpy libqwt-dev \ libusb-dev libusb-dev libusb-1.0-0-dev libgsl-dev python-wxgtk3.0 git qtcreator
Install UHD + GNURadio
Compile SWIG
sudo su sudo apt-get install bison flex cd /usr/local/src git clone https://github.com/swig/swig.git cd swig sudo apt-get install automake ./autogen.sh ./configure make make install
Compile UHD
mkdir -p /usr/local/src/SDR cd /usr/local/src/SDR git clone https://github.com/EttusResearch/uhd cd /usr/local/src/SDR/uhd/ git tag -l
git checkout v3.15.0.0 cd host mkdir build cd build cmake ../ make make test sudo make install sudo ldconfig export LD_LIBRARY_PATH=/usr/local/lib
Compile GNURadio
cd /usr/local/src/SDR git clone --recursive https://github.com/gnuradio/gnuradio.git cd gnuradio git checkout maint-3.8 git submodule update --init --recursive mkdir build cd build cmake -DCMAKE_BUILD_TYPE=Release -DPYTHON_EXECUTABLE=/usr/bin/python3 ../ make make test sudo make install sudo ldconfig
Install rtl_sdr
Lakukan
cd /usr/local/src/SDR git clone git://git.osmocom.org/rtl-sdr.git cd /usr/local/src/SDR/rtl-sdr/ mkdir build cd build cmake ../
make sudo make install sudo ldconfig
Aturan udev yang penting agar USB dongle terdetek dengan baik perlu di copy menggunakan perintah berikut
cd /usr/local/src/SDR/rtl-sdr/ sudo cp rtl-sdr.rules /etc/udev/rules.d/40-basic-permissions.rules /etc/init.d/udev restart
Kita dapat meng-unplug & replug USB dongle. Cek menggunakan perintah

Instalasi gr-air-modes
Lakukan
cd /usr/local/src/SDR git clone https://github.com/bistromath/gr-air-modes.git
cd /usr/local/src/SDR/gr-air-modes/ mkdir build cd build cmake .. make sudo make install sudo ldconfig
Jalankan gr-air-modes
Jalankan menggunakan perintah

Catatan Antenna
with a piece of wire in the rtl283 antenna socket resulted in decodes from one aircraft almost overhead. Time for a better 1090MHz antenna. The J pole previously used was easy to build from 2 pieces of semi rigid cable so time to make another.It was tuned with a tracking generator/directional coupler/ spectrum analyser and achieved 32dB retun loss after tweaking. Putting this on the end of 35' of cable in the loft resulted in many more decodes and a torrent of data in the terminal:-
Membuat Virtual Radar
Next time to plot the data. The article pointed to Virtual radar server at http://www.virtualradarserver.co.uk/Mono.aspx so this was installed. Launching it with and clicking on the http link for local host resulted in the following map with 8 aircraft:-
The rtl2832 is not as sensitive as the Modesbeast I also have but it is only 5% of the cost!
