GNU-Radio and UHD Python3 install

Either install GNU Radio via Pybomb or PPA Installation:

Pybmob Route

Install instructions were taken from from here

sudo apt-get install python3-pip
sudo pip3 install pybombs
pybombs auto-config
pybombs recipes add-defaults
pybombs prefix init ~/prefix-3.8 -R gnuradio-default
source ~/prefix-3.8/setup_env.sh
python3 ~/prefix-3.8/lib/uhd/utils/uhd_images_downloader.py

You can test your installation by connecting your usrp and running the program for a command line fft plotter:

python3 ~/prefix-3.8/lib/uhd/examples/python/curses_fft.py -f 2.4e9

Note that you will need to source the setup_env.sh everytime you open a terminal. So it is recommended to copy the command source ~/prefix-3.8/setup_env.sh into your ~/.bashrc with the command:

echo "source ~/prefix-3.8/setup_env.sh" >> ~/.bashrc
