OpenWebRX
|
|
=========
|
|
|
|
OpenWebRX is a multi-user SDR receiver software with a web interface.
|
|
|
|
|
|
|
|
It has the following features:
|
|
|
|
- <a href="https://github.com/simonyiszk/csdr">libcsdr</a> based demodulators (AM/FM/SSB),
|
|
- filter passband can be set from GUI,
|
|
- waterfall display can be shifted back in time,
|
|
- it extensively uses HTML5 features like WebSocket, Web Audio API, and <canvas>.
|
|
- it works in Google Chrome, Chromium (above version 37) and Mozilla Firefox (above version 28),
|
|
- currently supports RTL-SDR and HackRF; other SDR hardware may be easily added.
|
|
|
|
**News:**
|
|
- 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`.)
|
|
- 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.
|
|
|
|
## Setup
|
|
|
|
OpenWebRX currently requires Linux and python 2.7 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>
|
|
|
|
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>.
|
|
|
|
Please note that the server is also listening on the following ports (on localhost only):
|
|
|
|
- port 8888 for the I/Q source,
|
|
- 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
|
|
|
|
You can zoom the waterfall display by the mouse wheel. You can also drag the waterfall to pan across it.
|
|
|
|
The filter envelope can be dragged at its ends and moved around to set the passband.
|
|
|
|
However, if you hold down the shift key, you can drag the center line (BFO) or the whole passband (PBS).
|
|
|
|
## Setup tips
|
|
|
|
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>.
|
|
|
|
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`.
