Description

Skywave Linux is an operating system using bleding-edge technology to access broadcast, utility, military, and amateur radio signals from almost anywhere in the world, without regard to state media controls or censorship. Skywave Linux connects to a large and growing network of state-of-the art software defined radio (SDR) servers, making it possible to experience high performance SDR operation without large antennas or setting up a station on-site. All you need to do is boot the system on a computer with internet connectivity. Skywave Linux can also operate numerous types of SDR hardware. Downloading, installing and configuring SDR software can be difficult for many computer users; Skywave Linux eliminates the hassle by including several applications installrd, configured, and ready to run.

Features

  • WebSDR, OpenWebRX radio servers accessible via internet browser.
  • HPSDR servers accessible via QtRadio
  • HPSDR hardware also via cudaSDR
  • RTL-SDR plug-and-play functionality via CubicSDR, Gqrx, and QtRadio
  • RTL-SDR ADS-B tracking and mapping via Dump1090
  • RTL-SDR RDS decoding via Gqrx and Redsea
  • SDRPlay, Airspy radio hardware is supported.
  • LADSPA audio plugins for EQ/Compression/Limiting
  • WSJT -X / WSPR-X weak signal digimode software
  • Weather Satellite Decoding via WXtoImg
  • Satellite tracking with Gpredict
  • Trunked Radio System Reception with SDRTrunk
  • Radio firmware & data management with CHIRP
  • Kodi Media Center for conventional internet streaming

Supported SDR Types

Several types of software defined radios are supported by Skywave Linux:

  • WebSDR servers are located all over the world and provide easy access to the global airwaves through the web browser. In Skywave Linux, use the application called "WebSDR and OpenWebRX Servers" to call up the best servers. A modern web browser is all one needs to enjoy clean, stable, AM / FM / SSB reception using this cutting edge technology. Servers at the University of Twente (NL) and G4FPH, Stafford (UK) are particularly good.
  • OpenWebRX servers are a new type of internet accessible SDR, growing rapidly in number. Use the WebSDR and OpenWebRX Servers application to access several excellent sites around the world, such as Victoria, British Columbia (Canada), Overland Park, Kansas (USA) or Warrenton, Virginia (USA). OpenWebRX is installed in Skywave Linux and capable of running RTL-SDR, Softrock, SDRPlay, and other hardware.
  • RTL-SDR devices used on the local system. Just plug-and-play! CubicSDR and Gqrx are the main applications for receiving AM / FM / SSB modes. QtRadio (via the RTL-SDR controller script) offers advanced noise reduction and very high quality AM / SSB / CW reception, plus FM up to a 200 kHz bandwidth. Dump1090 (Mutability version) is for monitoring aircraft ADS-B transmissions. ADS-B mapping is available from Dump1090's built in webserver.
  • Ettus Research USRP devices, offering advanced features and high performance. Their hardware can cover frequencies from DC through 6 GHz in a diverse array of signal modes.
  • HPSDR hardware, for internet accessible receivers, is covered by QtRadio. Several servers, operated by volunteers around the world, are online 24 hours a day, and cover spectrum from LF through low VHF. Performance is excellent from these servers, and the radio configuration options in QtRadio make for a "professional grade" operating experience. To find servers, use the menu: Receiver > Quick Server List.
  • SDRPlay, Airspy, and BladeRF devices offer higher performance than RTL-SDR dongles. These devices feature stable and clean oscillators, sensitive front end circuitry, superior RF filters, broader RF bandwidths, and higher resulution ADC converters. CubicSDR and Gqrx are the applications built for running these devices.

For decoding RTTY, CW, PSK, WSJT, WSPR, RDS, and other digital radio transmission modes, the Fldigi the WSJT applications are installed. Simply start the applicatio and tune in a signal on the waterfall to decode. Weather satellite decoding is possible with the very capable WXtoImg application. Gpredict provides real-time satellite tracking data and doppler corrected tuning control for Gqrx. In some cases it may be necessary to use the Pulseaudio Preferences or Volume Control applications to configure the audio (output from the LADSPA audio processor plugins, networked sound, etc). Trunked radio systems may be monitored using SDRTrunk.

An experimental application, cudaSDR, expands support in Skywave Linux for High Performance Software Defined Radio. It offers automatic discovery of connected hardware and advanced operating features.

Conventional radio and video broadcast streams are also supported in Skywave Linux. Kodi Media Center provides access to thousands of music, talk, news, free-speech, and religious stations around the world. Editable playlists of IPTV and IPRADIO stations are located in the home folder.

Technical Notes

Skywave Linux is a 64 bit system, built on a base of Ubuntu 16.04 LTS, uses the Unity desktop environment, and draws on the capabilities of Ubuntu: software updating, graphics, system resource management, etc. It is the additional digital signal processing, networking, and signal decoding applications that set Skywave Linux apart from stock Ubuntu Linux. The default username is skywave and there is no password in the default system.

The radio software is largely compiled from source code and can be updated by end users with moderate computer skills, though Skywave Linux is designed for easy use by radio operators with basic computer skills. In fact, Skywave Linux was created to open the world of HPSDR and RTL-SDR operating to people who enjoy high performance radio but are not computer experts.

It may sometimes be advantageous for users to use encrypted connections which provide stronger privacy, security, and ability to circumvent censorship. For that purpose, the Bitmask and Lantern VPN applications are installed. In addition, basic PPTP and OpenVPN connections are included in the networking applet.
