How to Install GNU Radio on Ubuntu 22.04 LTS

GNU Radio is a powerful toolkit for developing software-defined radios (SDRs). It provides a wide range of signal processing blocks that can be used to implement a variety of SDRs and signal-processing systems. GNU Radio can be used with external RF hardware to create real-world SDRs or without hardware in a simulation-like environment. This flexibility makes GNU Radio an essential tool for anyone interested in developing cutting-edge SDRs. In addition, GNU Radio is released under the GNU General Public License, making it free to use and distribute. This makes it an ideal toolkit for both hobbyists and professional developers alike.

In the following tutorial, you will learn how to install GNU Radio on Ubuntu 22.04 LTS Jammy Jellyfish using the command line terminal along.

Update Ubuntu

First, update your system to ensure all existing packages are up to date to avoid conflicts.

sudo apt update && sudo apt upgrade -y

Install GNU Radio

The best method to utilize the APT package manager is to install the PPA by the “GNU Radio” team.

Run the following command to import the PPA.

sudo add-apt-repository ppa:gnuradio/gnuradio-releases -y

Before you continue, run an APT update to reflect the newly imported PPA.

sudo apt update

Now install GNU Radio

sudo apt install gnuradio -y

How to Launch GNU Radio

Launching can be done in a few ways now that you have the software installed.

First, in your terminal, type the following command to launch immediately.

gnuradio-companion

However, this is not practical, and you would use the following path on your desktop.

Activities > Show Applications> GNU Radio Companion.

Example:

Once open, you can begin using the software. For new users, I recommend checking out the GNU Radio wiki section to learn more about how to use it, as it’s pretty extensive.

Example:

gnu radio companion ubuntu 22.04 ltsPin

How to Update/Upgrade GNU Radio

The best method to ensure your GNU Radio is up-to-date is to open the command line terminal and run the following command.

sudo apt upgrade && sudo apt upgrade

The command will also ensure all other packages that use the APT package manager, including your system packages, are up-to-date. I suggest that users new to Linux run this command every so often, even if you have automatic GUI updates or notifications enabled, to ensure your system is working as intended.

Next, you should remove the PPA for users who will not use GNU Radio again.
