Skywave Linux ~ Global Online Listening

Skywave Linux ~ Global Online Listening

Skywave Linux is a 64 bit live system providing installed and configured software for accessing software defined radio servers locally and on the internet. With this operating system, a person may tune shortwave broadcasts, amateur radio, aeronautical, maritime, or other signals received at remote servers around the world.

SDR software is configured for popular devices, such as the RTL-SDR…

The Slickness of OpenWebRX

The more I use OpenWebRX the more I like how well it works with my rtl-sdr devices. For direct sampling as well as monitoring favorite VHF frequencies, it just works. Like a lot of Linux radio SDR apps, OpenWebRX requires several start parameters, but I use a script to get the parameters that change and preload the ones that don't. Hence, I merely click an icon and enter what frequency and mode to use. It is entirely possible to create scripts that will configure everything for a particular frequency or band. QtRadio, with its modules for softrock and RTL-SDRs is not as smooth or intuitive. More CPU load too. Gqrx and CubicSDR load more heavily too. If I could (and will, once I learn the code better) change anything, it would be the rather bland waterfall colors. There are better waterfalls on some online servers, so it is possible. Some noise limiting DSP would be a good feature too. Otherwise, listening is good and mostly limited by the hardware. Methinks things will slowly evolve away from these 8 bit, drifty RTL-SDRs to stable, clean, 12 to 16 bit devices resembling the Airspy and SDRPlay.

Skywave Linux 2.1 Released

After doing bug fixes and system updates, Skywave Linux 2.1 is uploading. Completion of the upload is expected at approximately 1000 UTC, 01/05/2017. Connectivity to SourceForge is terrible today; bit torrent downloads are faster and available now: http://linuxtracker.org/index.php?page=torrent-details&id=812deb56be026320a7a744c35352aab69c061b29

Skywave Linux 3.0 is released. This version has a different look, now using the MATE desktop environment. It is efficient and has visual appeal. We're now on the Xanmod Kernel 4.13, which makes for a responsive and stable base system. Audio now starts as a plain PulseAudio system, without plugins, for greater hardware compatibility. More wifi drivers are also included in Skywave Linux 3.0. Multiple desktops are enabled, so users can de-clutter and organize their activities on the system. As to the software defined radio applications, we now have four sources of remote servers: WebSDR, OpenWebRX (KiwiSDR), QtRadio/HPSDR, and RemoteSDRClient (SDRAnywhere). The latter is the newest and connects to shared RFSPACE radios. RTLSDR applications are now moving into new capabilities: simultaneous multichannel monitoring, data logging, and ability to stream audio to shoutcast servers. ACARS and VDL Mode 2 are now decodable, with logging. Bleeding-edge support for ADALM-PLUTO devices has been added. Kodi has received some updates and continues to offer streams from thousands and thousands of sources. Those stations sound great with the dynamics and EQ processing in PulseEffects. Overall, this version of Skywave Linux does more, makes better use of system resources, and is a joy to use.

Using the OpenWebRX-Subcarrier application, you can use your RTL-SDR to access subcarriers on wideband FM signals. Here we see a typical FM stereo baseband spectrum. On the left is the left + right audio. The stereo pilot tone is at 19 kHz, and above it is left - right audio. An RDS signal is above that, at 57 kHz. Military aviation monitors in the USA may find this a great way to access the ORDERWIRE channels used by TACAMO and certain VIP transports. An updated application, usable on any hardware, is in the works!

Skywave Linux 2.0 is released and uploading now. It's got a new lowlatency kernel, a fresh base of Ubuntu 16.04, and plenty of application upgrades. My favorite app is the upgraded Gqrx 2.6. It looks good and works beautifully.

Skywave Linux 1.6 is released. There's more support for those higher performance Airspy and SDRPlay devices. OpenWebRX is installed too, for the elegant interface and networked sharing worldwide. Trunked radio decoding is now supported with SDRTrunk. Get it on SourceForge or this torrent page: http://linuxtracker.org/index.php?page=torrent-details&id=c986b137c6918540daee5bae6ff1aea10275522a
