+Od kolegy [[http://ha5kfu.sch.bme.hu/openwebrx-quick-setup|HA5KFU]] hezky zpracovaná bashová dávka včetně věcných komentářů. Vše funguje na první dobrou. Kód je možné spustit ze souboru.
+<code>
+sudo apt-get install build-essential git libfftw3-dev cmake libusb-1.0-0-dev nmap
+#nmap itself is not used by OpenWebRX at all, but we need to install it because the ncat tool is packaged with it.
+#ncat is a netcat alternative which is used by OpenWebRX for internally distributing I/Q data,
+#  and also solves the incompatibility problems among netcat versions.
+#Fetch and build rtl-sdr, skip if already done (subdirectories will be created under the current directory).
+git clone git://git.osmocom.org/rtl-sdr.git
+cd rtl-sdr/
+mkdir build
+cd build
+cmake ../ -DINSTALL_UDEV_RULES=ON
+make
+sudo make install
+sudo ldconfig
+cd ../..
+#Disable the DVB-T driver, which would prevent the rtl_sdr tool from accessing the stick
+#(if you want to use it for DVB-T reception later, you should undo this change):
+sudo bash -c 'echo -e "\n# for RTL-SDR:\nblacklist dvb_usb_rtl28xxu\n" >> /etc/modprobe.d/blacklist.conf'
+sudo rmmod dvb_usb_rtl28xxu # disable that kernel module for the current session
+#Download OpenWebRX and libcsdr (subdirectories will be created under the current directory).
+git clone https://github.com/simonyiszk/openwebrx.git
+git clone https://github.com/simonyiszk/csdr.git
+#Compile libcsdr (which is a dependency of OpenWebRX)
+cd csdr
+make
+sudo make install
+#Edit OpenWebRX config or leave defaults
+nano ../openwebrx/config_webrx.py
+#Run OpenWebRX
+cd ../openwebrx
