SDR: test USB dongle

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 fftw3-dev python-numpy libqwt-dev \
libusb++-dev libusb-dev libusb-1.0-0-dev libgsl0-dev python-wxgtk2.6 git qtcreator

Install GNURadio

Lakukan

cd /usr/local/src/SDR
git clone git://gnuradio.org/gnuradio

Compile

cd /usr/local/src/SDR/gnuradio
mkdir build
cd build
cmake ../
make
sudo make install
sudo ldconfig

Install rtl_sdr

Lakukan

cd /usr/local/src/SDR
git clone git://git.osmocom.org/rtl-sdr.git

Masuk ke directory rtl-sdr & lakukan

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
