- it works in Google Chrome, Chromium (above version 37) and Mozilla Firefox (above version 28),

**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`.)
|
||||
- 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>.
|
||||
- Receivers can now be listed on <a href="http://sdr.hu/">SDR.hu</a>.

**News (2015-02-14)**
|
||||
- The DDC in *csdr* has been [manually optimized](https://github.com/simonyiszk/csdr/blob/2b54054a9f5de9a908ee075b488a5ee74f41ba18/libcsdr.c#L300) 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.
|
||||
- OpenWebRX now supports URLs like: `http://localhost:8073/#freq=145555000,mod=usb`
|
||||
- UI improvements were made, thanks to John Seamons and Gnoxter.

> When upgrading OpenWebRX, please make sure that you upgrade *csdr*, and install the new (optional) dependency *ncat*!

## OpenWebRX servers on SDR.hu
|
||||
|
||||
[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

||||
|

OpenWebRX currently requires Linux and python 2.7 to run.

|
||||
- <a href="http://sdr.osmocom.org/trac/wiki/rtl-sdr">rtl-sdr</a>
|
||||
- ncat (On Debian/Ubuntu, it is in the *nmap* package).
|
||||
|
||||
> By the way, *nmap* is a tool commonly used for auditing network security, and it is not used by OpenWebRX in any way. We need to install it, because the *ncat* command is packaged with it.
|
||||
>
|
||||
> *ncat* is a better *netcat* alternative, which is used by OpenWebRX for internally distributing the I/Q data stream. It also solves the problem of having different versions of *netcat* on different Linux distributions, which are not compatible by their command-line arguments.

- port 8888 for the I/Q source,
|

- port 4951 for the multi-user I/Q server.
