This content is a piece of our initiative to explain how to start your studies with RTL-SDR.
In this post we’ll explain about how to install the rtl-sdr driver.
To install the RTL-SDR device on a Linux computer is relatively quick and easy.
These instructions are designed to run on Linux distributions based on Debian or Ubuntu.
Installing the drivers:
1. Open the terminal and make sure you are in the home directory.
2. Update your Linux distribution:
sudo apt-get update
3. Install the necessary tools such as: git, cmake, build-essential
sudo apt-get install git
sudo apt-get install cmake
sudo apt-get install build-essential
4. Install the library called “libusb-1.0-0-dev” which provides access to USB devices.
sudo apt-get install libusb-1.0-0-dev
5. Download and install the RTL2832U from vendor site:
git clone git://git.osmocom.org/rtl-sdr.git
cmake ../ -DINSTALL_UDEV_RULES=ON
sudo make install
sudo cp ../rtl-sdr.rules /etc/udev/rules.d/
6. Create a “blacklist” to the default driver which loads automatically using the RTL-SDR device as a TV receiver, because this isn’t the functionality we want to use (tv receiver).
A. Access as administrator the directory: /etc/modprobe.d
B. Create a new file called “blacklist-rtl.conf” and add the following line in the file:
C. Save the file and reboot the machine.
7. After reboot the machine, test if the device is actually running. To test type the follow command in the terminal:
(rtl_test -t, command)
Don’t worry with the follow messages:
“PLL not locked”
“No E4000 tuner found, aborting”.
If you see these messages above it is a sign that your driver and your device is working properly and you are ready to install some applications like GQRX, Dump1090, CubicSDR and others…
