To start rtl_tcp on every ethernet interfaces and the port 1234:
<pre>
pi@sdr1 ~ $ rtl_tcp -a 0.0.0.0p 1234
Found 1 device(s).
Found Fitipower FC0013 tuner
to receive samples in GRC and control rtl_tcp parameters (frequency, gain, ...).

=== Calibration ===
Pour utiliser la grande partie des logiciel SDR il faut faire une calibration
==== Requirement ====
<pre>
sudo apt-get install libtool autoconf automake libfftw3-dev
</pre>
==== Installation ====
<pre>
git clone https://github.com/steve-m/kalibrate-rtl.git
cd kalibrate-rtl/
./bootstrap
./configure
make
sudo make install
</pre>
You may need to run this if you encounter some reference errors on Raspberry Pi:
<pre>
export PKG_CONFIG_PATH='/usr/lib/arm-linux-gnueabihf/pkgconfig/'
</pre>
==== Usage ====
On utilise les fréquences du GSM-900
<pre>
# kal -e 22 -s 900
Found 1 device(s):
