|
||||
It has the following features:
|

- <a href="https://github.com/simonyiszk/csdr">libcsdr</a> based demodulators (AM/FM/SSB),
|
||||
- <a href="https://github.com/simonyiszk/csdr">csdr</a> based demodulators (AM/FM/SSB/CW/BPSK31),
|
||||
- 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 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),
|

- *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.
