This repository contains packages for the following Linux distributions:

• Ubuntu 22.04 (Jammy Jellyfish) for amd64, arm64 architectures
• Debian 11 (Bullseye) for amd64, arm64, armhf architectures

Stanislav (LZ2SLL) has built an SD card image for RaspberryPi 4, containing a clean OpenWebRX+ installation. This image should support all common SDR devices out of the box. The RTL-SDR and SDRPlay devices have been confirmed to work with no additional modifications to the image. Please, keep in mind that this may not be the latest version of OpenWebRX+. Read on for the latest version.

Please note that this SD card image comes without the software support for digital modes (DMR, NXDN, etc), since the software decoder for these modes (mbelib) has questionable origins. In order to enable digital modes in this image, ssh into the user account you created while installing the image and type:

sudo install-softmbe.sh

Stanislav (LZ2SLL) has made two OpenWebRX+ Docker images that should run on any x64 PC, arm32 SBC, or arm64 SBC. The nightly image is updated daily and based on the latest OpenWebRX+ sources. The versioned image is based on the latest published OpenWebRX+ packages and should be identical to a normal OpenWebRX+ installation on Debian. The versioned image is somewhat bigger in size, but is also more stable.

In order to upgrade from a previous OpenWebRX+ version, do the following, as root:

apt update
apt upgrade

In order to add this repository to your Ubuntu system, do the following, as root:

wget -O - https://luarvique.github.io/ppa/openwebrx-plus.gpg | gpg --dearmor -o /etc/apt/trusted.gpg.d/openwebrx-plus.gpg
echo "deb [signed-by=/etc/apt/trusted.gpg.d/openwebrx-plus.gpg] https://luarvique.github.io/ppa/ubuntu ./" > /etc/apt/sources.list.d/openwebrx-plus.list
apt update

You should also have the original OpenWebRX repository added, since it contains some necessary packages. In order to add the original OpenWebRX repository to your Ubuntu system, do the following, as root:

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/ubuntu/ jammy main" > /etc/apt/sources.list.d/openwebrx.list
apt update

In order to add this repository to your Debian Bullseye system, do the following, as root:

wget -O - https://luarvique.github.io/ppa/openwebrx-plus.gpg | gpg --dearmor -o /etc/apt/trusted.gpg.d/openwebrx-plus.gpg
echo "deb [signed-by=/etc/apt/trusted.gpg.d/openwebrx-plus.gpg] https://luarvique.github.io/ppa/debian ./" > /etc/apt/sources.list.d/openwebrx-plus.list
apt update

You should also have the original OpenWebRX repository added, since it contains some necessary packages. In order to add the original OpenWebRX repository to your Debian Bullseye system, do the following, as root:

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

If you have a Debian Bookworm system, there is now an experimental OpenWebRX+ build available for you. Do the following, as root:

wget -O - https://luarvique.github.io/ppa/openwebrx-plus.gpg | gpg --dearmor -o /etc/apt/trusted.gpg.d/openwebrx-plus.gpg
echo "deb [signed-by=/etc/apt/trusted.gpg.d/openwebrx-plus.gpg] https://luarvique.github.io/ppa/bookworm ./" > /etc/apt/sources.list.d/openwebrx-plus.list
apt update

Debian Bookworm users must not add the original OpenWebRX repository to their system, since it contains Bullseye packages.

Finally, in order to install OpenWebRX+, do the following, as root:

apt install openwebrx

To make sure OpenWebRX+ is running, direct your local web browser to the following address:

http://localhost:8073/

You should see the OpenWebRX+ web interface, with the noise filter (NR) and tuning step (>-<) controls.

This repository offers the improved SoapySDRPlay3 device driver with the following changes from the original version:

• Fixed generic gain control, limiting it to the IFGR setting.
• Made RFGR setting a separate, optional prameter named "rf_gain".
• Fixed frequency correction (ppm) parameter.
• Fixed problems when switching from LIF to wideband ZIF mode.
• Fixed deadlocks when sending settings to the device.
• Added multiple retries when device does not accept a setting.
• Widened filters a little bit, reducing the "hump" size for most bandwidths.
• Added 1.536MHz bandwidth.

In order to install the improved SoapySDRPlay3 package, do the following, as root:

apt install soapysdr-module-sdrplay3

During installation, the SoapySDRPlay3 package should also install the latest SoapySDR and remove all locally built SoapySDR files from /usr/local. You will still need to download and install SDRPlay API from this page:

https://www.sdrplay.com/downloads/

SDRPlay API can also be installed as an unofficial package, by following these instructions:
