RTL-SDR Calibration
Antenna Setup
SDR at FIXME
We currently have two rtl_tcp instances running at FIXME:
- sdr1.fixme.ch:1234 (62.220.135.211:1234) (Raspberry PI, west window, MC's homemade VHF antenna)
- foo.fixme.ch:1234 (FIXME's internal server, north window, original UHF antenna)
Service
- The service is started with the following command is listen to the port 1234
sv start rtl-tcp
SDR Softwares
SDR++
- Simple and bloat free
- https://github.com/AlexandreRouma/SDRPlusPlus
Quisk
GNURadio
- GNURadio multimode
- Install on Debian 6
mkdir gnuradio; cd gnuradio wget http://www.sbrac.org/files/build-gnuradio; chmod a+x ./build-gnuradio; ./build-gnuradio
- On Debian 7: apt-get install gnuradio (???)
- On arch linux, a working package is in aur so you only need
yaourt -S gnuradio
- Install and use Multimode
svn co https://www.cgran.org/svn/projects/multimode/trunk/ gnuradio-multimode git clone git://git.osmocom.org/osmo-sdr.git ./multimode.py --devinfo=rtl_tcp=foo.fixme.ch:1234 --freq=98.5M --dmode=WFM --mthresh=-35 --vol=10
RTL-SDR
Debian Packages
apt intsall rtl-sdr
Sources
Requirement
sudo apt-get install git libusb-1.0-0-dev cmake build-essential
Build
git clone git://git.osmocom.org/rtl-sdr.git cd rtl-sdr/ mkdir build cd build cmake ../ -DDETACH_KERNEL_DRIVER=ON -DINSTALL_UDEV_RULES=ON make sudo make install sudo ldconfig cd .. sudo cp rtl-sdr.rules /etc/udev/rules.d/
Test the dongle
The test bellow is for a E4000 dongle.
$ rtl_test -t Found 1 device(s): 0: Terratec T Stick PLUS Using device 0: Terratec T Stick PLUS Found Elonics E4000 tuner Supported gain values (14): -1.0 1.5 4.0 6.5 9.0 11.5 14.0 16.5 19.0 21.5 24.0 29.0 34.0 42.0 Benchmarking E4000 PLL...

Info: This tool will continuously read from the device, and report if samples get lost. If you observe no further output, everything is fine. Reading samples in async mode...
Use rtl_tcp
To start rtl_tcp on every ethernet interfaces and the port 1234:
pi@sdr1 ~ $ rtl_tcp -a 0.0.0.0 p 1234 Found 1 device(s). Found Fitipower FC0013 tuner Using Terratec NOXON DAB/DAB+ USB dongle (rev 1) Tuned to 100000000 Hz. listening... Use the device argument 'rtl_tcp=0.0.0.0:1234' in OsmoSDR (gr-osmosdr) source 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
sudo apt-get install libtool autoconf automake libfftw3-dev
Installation
git clone https://github.com/steve-m/kalibrate-rtl.git cd kalibrate-rtl/ ./bootstrap ./configure make sudo make install
You may need to run this if you encounter some reference errors on Raspberry Pi:
export PKG_CONFIG_PATH='/usr/lib/arm-linux-gnueabihf/pkgconfig/'
Usage
On utilise les fréquences du GSM-900
# kal -e 22 -s 900
Found 1 device(s):

Using device 0: Generic RTL2832U OEM
Found Rafael Micro R820T tuner
Exact sample rate is: 270833.002142 Hz
