SDR++, The bloat-free SDR software
Here is the link to my video for this
This assumes that you have already installed your SDR drivers, for the RTL-SDR I use the Osmocom ones from https://www.rtl-sdr.com/rtl-sdr-quick-start-guide/
Having found how good SDR++ is on Windows 11, I wanted it on my Raspberry PI 4 too. I did find a YouTube article from 2021 by Kevin Loughin
who used Alexandre Rouma's install script and source code https://github.com/AlexandreRouma/SDRPlusPlus/
Kevin was using an older version of Raspberry Pi OS and also discovered that the installation script had been written blind (untested) and had a couple of issues, he referred to cloning direct from GitHub which is common practice, but that command was simply missing. No matter, I managed to change the commands script as below and started to compile it myself discovering that the Volk software v1.0 was no longer available. A helpful bash message informed me that v2 was available and I changed the script for that. I also had to include sudo and a mkdir for the CMake folder and set those permissions for it to work. After a very long wait and a few edits as I am running the current version of Raspberry PI OS 32 bit Buster. I compiled it for an RTL-SDR, but you can change one command and compiling for other versions should be really straightforward.
My script for the RTL-SDR is below, I will put this on my GitHub too.
https://github.com/TekMaker/SDRplus
#!/bin/sh set -e [ $(id -u) = 0 ] && echo "Please do not run this script as root" && exit 100 echo "Installing dependencies" sudo apt update sudo apt install -y build-essential cmake git libfftw3-dev libglfw3-dev libglew-dev libvolk2-dev libsoapysdr-dev libairspyhf-dev libairspy-dev \ libiio-dev libad9361-dev librtaudio-dev libhackrf-dev librtlsdr-dev libbladerf-dev liblimesuite-dev p7zip-full wget git clone https://github.com/AlexandreRouma/SDRPlusPlus cd SDRPlusPlus echo "Preparing build" sudo mkdir -p build cd build sudo mkdir -p CMakeFiles cmake .. -DOPT_BUILD_RTL_SDR_SOURCE=ON echo "Building" make echo "Installing" sudo make install echo "Done!"
Save this file as rpi_install.sh
then chmod +x rpi-install.sh
./rpi_install.sh
If it doesn't go smoothly try entering the commands one line at a time into the terminal, you can skip the echo commands. I have built this on two installs so far with no problems.
If you want to compile for other radios either edit or add extra lines like this one "cmake .. -DOPT_BUILD_RTL_SDR_SOURCE=ON", for more information about this go to the Module List, and look for the Sources list on the github page https://github.com/AlexandreRouma/SDRPlusPlus/blob/master/readme.md.
Let me know how you get on with this!
