It has the following features:
- <a href="https://github.com/simonyiszk/csdr">libcsdr</a> based demodulators (AM/FM/SSB),
2014-11-29 00:10:36 +00:00
- filter passband can be set from GUI,
2014-11-29 00:07:10 +00:00
- waterfall display can be shifted back in time,
2014-11-29 00:10:36 +00:00
- it extensively uses HTML5 features like WebSocket, Web Audio API, and &lt;canvas&gt;.
2014-11-29 00:07:10 +00:00
- it works in Google Chrome, Chromium (above version 37) and Mozilla Firefox (above version 28),
2017-04-04 16:18:28 +00:00
- currently supports RTL-SDR, HackRF, SDRplay, AirSpy and many other devices, see the <a href="https://github.com/simonyiszk/openwebrx/wiki/">OpenWebRX Wiki</a>.

**News (2015-08-18)**
- My BSc. thesis written on OpenWebRX is <a href="http://openwebrx.org/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`.)
2015-08-17 18:53:48 +00:00
- OpenWebRX now uses <a href="https://github.com/simonyiszk/csdr#sdrjs">sdr.js</a> (*libcsdr* compiled to JavaScript) for some client-side DSP tasks.
2016-02-14 17:54:18 +00:00
- 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.
2016-02-14 18:36:18 +00:00
- Also we use *ncat* instead of *rtl_mus*, and it is 3 times faster in some cases.
2016-02-14 17:53:06 +00:00
- OpenWebRX now supports URLs like: `http://localhost:8073/#freq=145555000,mod=usb`
2016-02-14 17:51:22 +00:00
- UI improvements were made, thanks to John Seamons and Gnoxter.

**News (2017-04-04)**
2017-04-04 16:16:20 +00:00
- *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.
2017-04-04 16:15:08 +00:00
- 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.
2016-02-14 18:36:49 +00:00
> When upgrading OpenWebRX, please make sure that you also upgrade *csdr*, and install the new dependency, *ncat*!

## OpenWebRX servers on SDR.hu
2016-02-14 17:23:34 +00:00
2016-02-14 17:53:48 +00:00
[SDR.hu](http://sdr.hu) is a site which lists the active, public OpenWebRX servers. Your receiver [can also be part of it](http://sdr.hu/openwebrx), if you want.

## Setup
2014-11-29 17:50:25 +00:00
OpenWebRX currently requires Linux and python 2.7 to run.
2014-11-29 00:07:10 +00:00
First you will need to install the dependencies:
2014-11-29 00:07:47 +00:00
2014-11-29 00:07:10 +00:00
- <a href="https://github.com/simonyiszk/csdr">libcsdr</a>
- <a href="http://sdr.osmocom.org/trac/wiki/rtl-sdr">rtl-sdr</a>
After cloning this repository and connecting an RTL-SDR dongle to your computer, you can run the server:
python openwebrx.py
You can now open the GUI at <a href="http://localhost:8073">http://localhost:8073</a>.
2014-11-29 00:12:17 +00:00
Please note that the server is also listening on the following ports (on localhost only):
2014-11-29 00:07:47 +00:00
2014-11-29 00:07:10 +00:00
- port 4951 for the multi-user I/Q server.
Now the next step is to customize the parameters of your server in `config_webrx.py`.

## Usage tips
2014-11-29 13:09:03 +00:00
You can zoom the waterfall display by the mouse wheel. You can also drag the waterfall to pan across it.
2014-11-29 13:05:39 +00:00
2014-11-29 00:07:47 +00:00
The filter envelope can be dragged at its ends and moved around to set the passband.
2014-11-29 00:07:10 +00:00
2014-11-29 13:09:03 +00:00
However, if you hold down the shift key, you can drag the center line (BFO) or the whole passband (PBS).

2015-10-11 16:52:45 +00:00
If you have any problems installing OpenWebRX, you should check out the <a href="https://github.com/simonyiszk/openwebrx/wiki">Wiki</a> about it, which has a page on the <a href="https://github.com/simonyiszk/openwebrx/wiki/Common-problems-and-their-solutions">common problems and their solutions</a>.
2014-11-29 12:56:56 +00:00
2015-10-11 16:51:37 +00:00
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.
2014-11-30 17:00:53 +00:00
2016-02-14 18:28:06 +00:00
If you want to run OpenWebRX on a remote server instead of *localhost*, do not forget to set *server_hostname* in `config_webrx.py`.
