**News (2019-06-30 by DD5JFK)**
- I have done some major rework on the openwebrx core, and I am planning to continue adding more features in the near future. Please check this place for updates.
- My work has not been accepted into the upstream repository, so you will need to chose between my fork and the official version.
- I have enabled the issue tracker on this project, so feel free to file bugs or suggest enhancements there!
- This version sports the following new and amazing features:
- Support of multiple SDR devices simultaneously
- Support for multiple profiles per SDR that allow the user to listen to different frequencies
- Support for digital voice decoding
- Feature detection that will disable functionality when dependencies are not available (if you're missing the digital buttons, this is probably why)
- Raspbian SD Card Images and Docker builds available (see below)
- I am currently working on the feature set for a stable release, but you are more than welcome to test development versions!
**News (2015-08-18)**
- My BSc. thesis written on OpenWebRX is <a href="https://sdr.hu/static/bsc-thesis.pdf">available here.</a>
- Several bugs were fixed to improve reliability and stability.
- OpenWebRX now supports compression of audio and waterfall stream, so the required network uplink bandwidth has been decreased from 2 Mbit/s to about 200 kbit/s per client! (Measured with the default settings. It is also dependent on `fft_size`.)
- OpenWebRX now uses <a href="https://github.com/simonyiszk/csdr#sdrjs">sdr.js</a> (*libcsdr* compiled to JavaScript) for some client-side DSP tasks.
- Receivers can now be listed on <a href="http://sdr.hu/">SDR.hu</a>.
- License for OpenWebRX is now Affero GPL v3.
**News (2016-02-14)**
- The DDC in *csdr* has been manually optimized for ARM NEON, so it runs around 3 times faster on the Raspberry Pi 2 than before.
- Also we use *ncat* instead of *rtl_mus*, and it is 3 times faster in some cases.
- OpenWebRX now supports URLs like: `http://localhost:8073/#freq=145555000,mod=usb`
- UI improvements were made, thanks to John Seamons and Gnoxter.
**News (2017-04-04)**
- *ncat* has been replaced with a custom implementation called *nmux* due to a bug that caused regular crashes on some machines. The *nmux* tool is part of the *csdr* package.
- Most consumer SDR devices are supported via <a href="https://github.com/rxseger/rx_tools">rx_tools</a>, see the <a href="https://github.com/simonyiszk/openwebrx/wiki/Using-rx_tools-with-OpenWebRX">OpenWebRX Wiki</a> on that.
**News (2017-07-12)**
- OpenWebRX now has a BPSK31 demodulator and a 3D waterfall display.

## Setup
OpenWebRX currently requires Linux and python 2.7 to run.
### Raspberry Pi SD Card Images
Probably the quickest way to get started is to download the [latest Raspberry Pi SD Card Image](https://s3.eu-central-1.amazonaws.com/de.dd5jfk.openwebrx/2019-06-21-OpenWebRX-full.zip). It contains all the depencencies out of the box, and should work on all Raspberries up to the 3B+.
This is based off the Raspbian Lite distribution, so [their installation instructions](https://www.raspberrypi.org/documentation/installation/installing-images/) apply.
Please note: I have not updated this to include the Raspberry Pi 4 yet. (It seems to be impossible to build Rasbpian Buster images on x86 hardware right now. Stay tuned!)
Once you have booted a Raspberry with the SD Card, it will appear in your network with the hostname "openwebrx", which should make it available as http://openwebrx:8073/ on most networks. This may vary depending on your specific setup.
For Digital voice, the minimum requirement right now seems to be a Rasbperry Pi 3B+. I would like to work on optimizing this for lower specs, but at this point I am not sure how much can be done.
### Docker Images
For those familiar with docker, I am providing [recent builds and Releases for both x86 and arm processors on the Docker hub](https://hub.docker.com/r/jketterl/openwebrx). You can find a short introduction there.
### Manual Installation
OpenWebRX currently requires Linux and python 3 to run.
First you will need to install the dependencies:
- <a href="https://github.com/simonyiszk/csdr">libcsdr</a>
- <a href="http://sdr.osmocom.org/trac/wiki/rtl-sdr">rtl-sdr</a>
- [csdr](https://github.com/simonyiszk/csdr)
- [rtl-sdr](http://sdr.osmocom.org/trac/wiki/rtl-sdr)
Optional Dependencies if you want to be able to listen do digital voice:
- [digiham](https://github.com/jketterl/digiham)
- [dsd](https://github.com/f4exb/dsdcc)
After cloning this repository and connecting an RTL-SDR dongle to your computer, you can run the server:

Please note that the server is also listening on the following ports (on localhost only):
- port 4951 for the multi-user I/Q server.
- ports 4950 to 4960 for the multi-user I/Q servers.
Now the next step is to customize the parameters of your server in `config_webrx.py`.

Sometimes the actual error message is not at the end of the terminal output, you may have to look at the whole output to find it.
If you want to run OpenWebRX on a remote server instead of *localhost*, do not forget to set *server_hostname* in `config_webrx.py`.
