== RTL-SDR ==

This page will provide you with descriptions to build your own RTL-SDR station using a USB DVB receiver on Linux.
Mostly intended for a Debian environment but packages are installed from source where possible to make it flexible to other environments.

=== Installation using apt-get ===
<code>
sudo apt-get install rtl-sdr
</code>

=== Installation from source ===
<code>
apt-get update 
</code> <br>

<code>
apt-get install git cmake libboost-all-dev libusb-1.0-0-dev python-scitools portaudio19-dev sox -y
</code> <br>

<code>
mkdir /home/sdr
</code> <br>

<code>
cd /home/sdr
</code> <br>

<code>
git clone git://git.osmocom.org/rtl-sdr.git
</code> <br>

<code>
cd /rtl-sdr
</code> <br>

<code>
mkdir build
</code> <br>

<code>
cmake ../ 
</code> <br>

<code>
make</code> <br>

<code>
make install
</code> <br>

<code>
cp /home/sdr/rtl-sdr/rtl-sdr.rules /etc/udev/rules.d/
</code> <br>


== Checking your dongle == 
=== List the dongle ===
<code>
lsusb
</code><br>

<pre>
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 138a:00ab Validity Sensors, Inc. 
Bus 001 Device 007: ID 0bda:2838 Realtek Semiconductor Corp. RTL2838 DVB-T
Bus 001 Device 002: ID 04f2:b669 Chicony Electronics Co., Ltd 
Bus 001 Device 005: ID 8087:0aaa Intel Corp. 
Bus 001 Device 006: ID 413c:3010 Dell Computer Corp. Optical Wheel Mouse
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
</pre>

So mine is :
<pre>
Bus 001 Device 007: ID 0bda:2838 Realtek Semiconductor Corp. RTL2838 DVB-T
</pre>

=== Test the dongle ===
==== Test using rtl_test ====
<code>
root@lphenixhq:/opt/rtl-sdr# rtl_test -t
</code><br>

<pre>
Found 1 device(s):
  0:  Realtek, RTL2838UHIDIR, SN: 00000001

Using device 0: Generic RTL2832U OEM
Detached kernel driver
Found Fitipower FC0012 tuner
Supported gain values (5): -9.9 -4.0 7.1 17.9 19.2 
Sampling at 2048000 S/s.
No E4000 tuner found, aborting.
Reattached kernel driver
</pre>
Yes, a working dongle!

==== Test using RTL_FM ====
 
(http://kmkeen.org/rtl-dmod-guide/)<br>
<code>
rtl_fm -M wbfm -f '''105.1M''' | play -r 32k -t raw -e s -b 16 -c1 -V1
</code><br>

105.1M is my local station, Haarlem FM, change it for yours!<br>

You can also scan a range, for example airplane radio traffic</br>
<code>
rtl_fm -M am -f 118M-138M:25k -s 12k -g 50 -l 200 | play -r 12k
</code><br>
Find airport info on SkyVector 
https://skyvector.com/airport/EHAM/Amsterdam-Schiphol-Airport<br>

== Spectrum analyzing ==
You might have to select your device in Options<br>

<code>
apt install gqrx-sdr
</code><br>

<code>
gqrx
</code><br>

== Messages between tower and airplanes, ACARS ==
<code>
git clone https://github.com/TLeconte/acarsdec
</code> <br>

<code>
cd acarsdec
</code><br>

<code>
mkdir build
</code><br>

<code>
cd build
</code><br>

<code>
cmake .. -Drtl=ON 
</code><br>

<code>
make</code><br>

<code>
sudo make install</code><br>

==== Check the traffic from the commandline, using acarsdec ====
<code>
acarsdec -r 0 131.525 131.725
</code><br>

== Dump1090 ==
This translates ADSR messages containing altitude and speed of airplanes<br>
You need a google developer key to see mapinfo :-(<br>
But you can also connect to it from VirtualRadar, see below<br>
=== Install ===
<code>
git clone https://github.com/antirez/dump1090
</code> <br>

<code>
cd dump1090
</code><br>

<code>
make
</code><br>

=== Check info from Airplanes ===
<code>
./dump1090 --enable-agc --interactive --agressive
</code><br>

Play with it and check on http://localhost:8080<br>
<code>
./dump1090 --enable-agc --net --agressive
</code><br>

== Virtual Radar ==
Now we are getting to the fun part and see things<br>

Make sure to have mono installed<br>
<code>
sudo apt-get install mono-complete
</code><br>

Go to the dir you want to install the software<br>
<code>
mkdir /opt/virtualradar
</code><br>

<code>
wget http://www.virtualradarserver.co.uk/Files/VirtualRadar.tar.gz
</code><br>

<code>
tar xzvf VirtualRadar.tar.gz
</code><br>

==== Create the config file ====

<code>
vi VirtualRadar.exe.config
</code><br>

Copy this block
<pre>
<?xml version="1.0"?>
<configuration>
    <configSections>
    </configSections>
    <startup>
        <supportedRuntime version="v2.0.50727"/>
    </startup>
    <runtime>
        <assemblyBinding  xmlns="urn:schemas-microsoft-com:asm.v1">
            <dependentAssembly>
                <assemblyIdentity name="Mono.Data.Sqlite"
                                  publicKeyToken="0738eb9f132ed756"
                                  culture="neutral" />
                <bindingRedirect oldVersion="2.0.0.0"
                                 newVersion="4.0.0.0" />
            </dependentAssembly>
        </assemblyBinding>
    </runtime>
</configuration>
</pre>

==== Start VirtualRadar ====
Start dump1090 first after inserting the dongle<br>
<code>
/opt/dump1090 --enable-agc --interactive --agressive
</code><br>
<code>
mono VirtualRadar.exe
</code><br>

==== Visit localhost ====
<code>
http://localhost:8080/VirtualRadar/desktop.html
</code><br>
==== Change the port for the webserver ====

In the configuration folder create a text file called InstallerConfiguration.xml and paste the following<br>
<pre>
<?xml version="1.0" encoding="utf-8" ?>
<InstallerSettings xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <WebServerPort>8080</WebServerPort>
</InstallerSettings>
</pre><br>
