OpenWebRX is a multi-user SDR receiver that can be operated from any web browser without the need for any additional client software.

This is a high level guide rather than an in-depth tutorial.

• Raspberry Pi 4b
• SDR Play RSP1

NB there is an issue when using Docker with the initialisation of the RSP1 when used with Docker which requires 'sudo docker compose restart' after the host system boots. More info

1. Burn Raspberry Pi OS Lite 64 bit to a micro SD card
2. Boot Pi, SSH into it
3. Then, execute the following, replacing the admin username/password as required. (You can remove them after first startup.)

curl -sSL https://get.docker.com/ | sudo sh
mkdir openwebrx
cd openwebrx
echo "version: '3.3'
services:
  openwebrx:
    restart: unless-stopped
    environment:
      - OPENWEBRX_ADMIN_USER=admin
      - OPENWEBRX_ADMIN_PASSWORD=rad10
    tmpfs: /tmp/openwebrx
    devices:
      - /dev/bus/usb
    ports:
      - '8073:8073'
    volumes:
      - 'openwebrx-settings:/var/lib/openwebrx'
    image: 'jketterl/openwebrx:stable'
volumes:
  openwebrx-settings:" > docker-compose.yml
sudo docker compose up -d
sudo docker compose restart

Then in your browser, access:

http://hostname-or-ip-of-your-pi:8073

You can access the settings screen by clicking Settings in the top right, and using the username admin and password rad10. In here, you would set up things like SDR profiles, waterfall settings, decoding etc.

Remember, due to the issue outlined above, the following is required on host reboot:

cd openwebrx
sudo docker compose restart

If this is a non-starter for you, you might like to go for the bare OS approach instead, removing Docker from the equation, which follows:

Download and install 64 bit Raspberry Pi OS Lite. Then:

Install SDRPlay driver:

mkdir sdrplay
cd sdrplay
wget https://www.sdrplay.com/software/SDRplay_RSP_API-ARM64-3.07.1.run
chmod +x SDRplay_RSP_API-ARM64-3.07.1.run
./SDRplay_RSP_API-ARM64-3.07.1.run
sudo reboot

Install SoapySDR:

sudo apt install git build-essential cmake g++ libpython3-dev python3-numpy swig python3-distutils
git clone https://github.com/pothosware/SoapySDR.git
cd SoapySDR
mkdir build
cd build
cmake ..
make -j4
sudo make install
sudo ldconfig
SoapySDRUtil --info

Install SoapySDR module for SDRPlay:

cd ~
git clone https://github.com/pothosware/SoapySDRPlay.git
cd SoapySDRPlay
mkdir build
cd build
cmake ..
make
sudo make install

Install OpenWebRX:

sudo su
wget -O - https://repo.openwebrx.de/debian/key.gpg.txt | gpg --dearmor -o /usr/share/keyrings/openwebrx.gpg
echo "deb [signed-by=/usr/share/keyrings/openwebrx.gpg] https://repo.openwebrx.de/debian/ bullseye main" > /etc/apt/sources.list.d/openwebrx.list
apt update && apt install openwebrx
