This project is based on SDR++ code originaly written by Alexandre Rouma. This is modified version of code and explicitly marked as changed, so their problems will not be attributed erroneously to authors of original SDR++ code.

The project in this repository is maintained by qrp73. The code is provided "as is" under GPL-3.0 license and with no warranty.

Your feedback and bug reports are welcome. Feel free to report issues and discuss technical details and functionality.

Have good day and 73

• added SDL2 OpenGL ES backend (can be enabled in cmake) which supports Linux KMS DRM mode, it can run without desktop. Tested on Raspberry Pi Zero 2W.
• fixed waterfall zoom
• SNR meter replaced with level meter + level and SNR text indication
• unity gain for FFT and window functions
• added Blackman-Harris-7, Blackman-Harris-4, Hamming and Hann window functions
• added 1M FFT
• fixed AM,FM,WFM,SSB,DSB bandwidth
• fixed units misspelling
• improved squelch to reduce false triggering
• rtl_sdr_source: fixed sample conversion
• hpsdr_source: added new module for HPSDR protocol enabled devices
• file_source: code replaced with a new multi-format support (supported: FLOAT 32/64 bit and PCM 8/16/24/32 bit)
• audio_source: added support for mono source, fixed error logging
• recorder: fixed default filename pattern
• recorder: added 24-bit PCM support
• frequency_manager: fixed jittery label position
• some minor fixes

The only hardware that I have is RTLSDRv3 and custom FPGA DSP chains for different hardware which are using my custom or HPSDR protocol. So, this project is targeted primary on RTLSDRv3 and HPSDR protocol devices. But feel free to report issues with other hardware.

You can download the latest code version from this repository: https://github.com/qrp73/SDRPP

You can install SDRPP with manual build.

Install pre-requisites:

sudo apt update
sudo apt install -y \
   git wget p7zip-full build-essential cmake cmake-curses-gui libtool xxd autoconf \
   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 \
   libcodec2-dev libzstd-dev portaudio19-dev libsdl2-dev

If libvolk2-dev is not available, use libvolk1-dev.

Build and install:

git clone https://github.com/qrp73/SDRPP
cd SDRPP
mkdir -p build && cd build
cmake ..
make -j4
sudo make install

Build with SDL2 backend to use in KMS DRM mode (don't requires graphics desktop to run):

git clone https://github.com/qrp73/SDRPP
cd SDRPP
mkdir -p build && cd build
cmake -DOPT_BACKEND_GLFW=OFF -DOPT_BACKEND_SDL2=ON ..
make -j4
sudo make install

Run:

sdrpp

When running with SDL2 backend you can exit to command line with Alt+F4.

cd SDRPP/build
sudo make uninstall
make clean

sudo rm /usr/bin/sdrpp
sudo rm -r /usr/lib/sdrpp
sudo rm -r /usr/share/sdrpp
sudo rm -r /home/<USERNAME>/.config/sdrpp
