GQRX on Ubuntu 17.10

This is done from a fresh install of Ubuntu that is updated with sudo apt-get update and sudo apt-get upgrade. First lets do a little preparatory work from the terminal.

sudo apt-get install git cmake rtl-sdr librtlsdr0 librtlsdr-dev miri-sdr libmirisdr0 libmirisdr-dev

Now for GQRX

sudo add-apt-repository -y ppa:bladerf/bladerf
sudo add-apt-repository -y ppa:ettusresearch/uhd
sudo add-apt-repository -y ppa:myriadrf/drivers
sudo add-apt-repository -y ppa:myriadrf/gnuradio
sudo add-apt-repository -y ppa:gqrx/gqrx-sdr
sudo apt-get update
sudo apt-get install gqrx-sdr gr-iio

Now that is done. Lets install the upstream driver for gr-osmosdr which has PlutoSDR included.

mkdir src
sd src
git clone https://github.com/csete/gr-osmosdr-gqrx
cd gr-osmosdr-gqrx/
git checkout plutosdr
mkdir build
cd build/
cmake ../
make
sudo make install
sudo ldconfig

Now when you open GQRX and have your PlutoSDR plugged in it should show up. You Done Did It.
