Time Series Capture System based on Software Defined Radios
sdrTcap is a collection of code for long term capturing of RF signals using software defined radio and storing them continously on the hard disk. It has been tested using NESDR-Mini-2+, NESDR Nano 2 and NESDR SMArt v5. More info about these devices can be found on the NooELEC website.
This is a pure python code that utilizes the RTL-SDR driver.
Before you install this code, make sure the driver is installed on your system:
sudo apt install -y rtl-sdr
You should be able to use the device as a normal user. If you have permission problems, please follow the instructions available on this site. In short:
first find out the vendor ID of your device using lsusb, which will look something like this:
Bus 003 Device 017: ID 0bda:2838 Realtek Semiconductor Corp. RTL2838 DVB-T
then you create a file /etc/udev/rules.d/10-rtl-sdr.rules with the content from the vendor ID:
SUBSYSTEM=="usb", ATTRS{idVendor}=="0bda", ATTRS{idProduct}=="2838", MODE="0666"
then restart udev:
sudo udevadm control --reload-rules
sudo udevadm trigger
Finally continue with:
pip3 install -r requirements.txt
pip3 install .
For uninstalling you can type:
pip3 uninstall sdrTcap
This code is like the above, with the difference - as the name suggests - of using the Soapy driver. This code is taken over from the examples available on the GR4 repositors. The original version can be found on the GR4 repository. It is based on GNURadio4 for accessing and processing digitised signals from Software Defined Radio (SDR). The current version aims at working with LIME SDR and is based on the SoapySDR integration inside the GR4.
Starting from a fresh image / ubuntu:
sudo apt install git cmake g++ libboost-all-dev libgmp-dev swig python3-numpy python3-mako python3-sphinx python3-lxml doxygen libfftw3-dev libsdl1.2-dev libgsl-dev libqwt-qt5-dev libqt5opengl5-dev python3-pyqt5 liblog4cpp5-dev libzmq3-dev python3-yaml python3-click python3-click-plugins python3-zmq python3-scipy python3-gi python3-gi-cairo gobject-introspection gir1.2-gtk-3.0
sudo apt install soapyosmo-common0.7 soapyremote-server soapysdr-module-airspy soapysdr0.7-module-airspy soapysdr-module-all soapysdr0.7-module-all soapysdr-module-audio soapysdr0.7-module-audio soapysdr-module-bladerf soapysdr0.7-module-bladerf soapysdr-module-hackrf soapysdr0.7-module-hackrf soapysdr-module-lms7 soapysdr0.7-module-lms7 soapysdr-module-mirisdr soapysdr0.7-module-mirisdr soapysdr-module-osmosdr soapysdr0.7-module-osmosdr soapysdr-module-redpitaya soapysdr0.7-module-redpitaya soapysdr-module-remote soapysdr0.7-module-remote soapysdr-module-rtlsdr soapysdr0.7-module-rtlsdr soapysdr-module-uhd soapysdr0.7-module-uhd soapysdr-tools
then comes:
sudo apt install uhd-host uhd-soapysdr limesuite limesuite-udev
you should be able to check your card by:
LimeUtil --find
SoapySDRUtil --info
SoapySDRUtil --find
you can also update the card by doing sudo LimeUtil --update, but this is not always recommended.
At this point, you sould also be able to use GQRX which is a very nice code.
Compilation steps:
mkdir build
cd build
cmake -G Ninja -DCMAKE_C_COMPILER=clang-18 -DCMAKE_CXX_COMPILER=clang++-18 -DCMAKE_BUILD_TYPE=Debug -DLLVM_USE_LINKER=lld ..
ninja
