== SDR at FIXME ==
<s>
We currently have two '''rtl_tcp''' instances running at FIXME:
* sdr1.fixme.ch:1234 (62.220.135.211:1234) ([http://www.raspberrypi.org/ Raspberry PI], west window, MC's homemade VHF antenna)
* foo.fixme.ch:1234 (FIXME's internal server, north window, original UHF antenna)

Supported gain values (23): -9.9 -7.3 -6.5 -6.3 -6.0 -5.8 -5.4 5.8 6.1 6.3 6.5 6.7 6.8 7.0 7.1 17.9 18.1 18.2 18.4 18.6 18.8 19.1 19.7
Sampling at 2048000 S/s.
Info: This tool will continuously read from the device, and report if
samples get lost. If you observe no further output, everything is fine.

=== 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>
