SDR

Quickstart

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)

GNURadio

• GNURadio multimode
• Install

 mkdir gnuradio; cd gnuradio
 wget http://www.sbrac.org/files/build-gnuradio; chmod a+x ./build-gnuradio; ./build-gnuradio
 svn co svn co https://www.cgran.org/svn/projects/multimode/trunk/ gnuradio-multimode
 git clone git://git.osmocom.org/osmo-sdr.git

• Use Multimode

 ./multimode.py --devinfo=rtl_tcp=foo.fixme.ch:1234 --freq=98.5M --dmode=WFM --mthresh=-35 --vol=10

SDR#

sudo apt-get install mono-complete monodevelop
sudo apt-get install libportaudio2
svn co https://subversion.assembla.com/svn/sdrsharp/trunk sdrsharp
cd sdrsharp
xbuild /t:Rebuild /p:Configuration=Release SDRSharp.sln /p:Platform=x86
cd Release
sudo ln -s /usr/local/lib/librtlsdr.so librtlsdr.dll
sudo ln -s /usr/lib/x86_64-linux-gnu/libportaudio.so.2 libportaudio.so
mono SDRSharp.exe

Multimon-NG

git clone https://github.com/EliasOenal/multimonNG.git
cd multimonNG
mkdir build
cd build
qmake ../multimon-ng.pro
make
sudo make install

Goal

• Install an SDR reception station at FIXME based on rtl-sdr, a DVB-T USB Stick and a Raspberry Pi.

HOWTO

pi@sdr1 ~ $ rtl_tcp -a 0.0.0.0
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, ...).
