OpenWebRX
|
||||
=========
|
||||
|
||||
Open source web-based SDR receiver software
|
||||
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 bandwith, BFO, PBS 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 only supports RTL-SDR, but other SDR hardware may be easily added.
|
||||
|
||||
## Setup
|
||||
|
||||
OpenWebRX currently requires a Linux machine 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 it 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`.
|
||||
|
||||
Actually, if you do something cool with OpenWebRX (or just have a problem), please drop me a mail: Andras Retzler, HA7ILM >randras@sdr.hu<.
|
||||
I would like to maintain a list of online amateur radio receivers on <a href="http://sdr.hu/">sdr.hu</a>.
|
||||
|
||||
## Usage tips
|
||||
|
||||
The filter envelope can be dragged at its ends and moved.
|
||||
|
||||
However, if you hold the shift key, you can drag the center line (BFO) or the passband (PBS).

PREAMBLE
|
||||
The goals of the Open Font License (OFL) are to stimulate worldwide

|
||||
to any document created using the fonts or their derivatives.
