During times of emergency and crisis, radio hobbyists worldwide turn on their radios and tune to the shortwave radio spectrum for context, perspective, and insight into what is happening around the globe. If you are looking for the last unskinned SDR build, check here. For the latest SDR build with collapsible panels check here.
For the latest dotnet 4. The basic SDR download without any third party plugins includes a standard FFT display and waterfall, a frequency manager, recording plugin and a digital noise reduction plugin. The official installation instructions can be found here. Users will also find an Audio FFT and waterfall display on the bottom of the screen.
The output audio can also be bandpass filtered by dragging the filter borders on the display. Bandpass filtering the audio can really help clean up a noisy signal. The audio processing also supports placing of notch filters either manually or automatically. Traditional ham radio users will also enjoy the S-units signal strength meter and the built in frequency manager.
Be sure you install version 2 and not V1. To compile your own dlls see the instructions here , otherwise download the dlls directly from the bottom of this link.
Built in are also several DSP features like a noise blanker, noise reduction filter, notch filter and squelch options. The EMNS noise reduction filter is particularly good at automatically cleaning up and clarifying voice signals.
Furthermore, sdr-radio V2 not V3 yet has an excellent remote server which will allow you to easily set up and connect to a remote RTL-SDR server over a network or the internet. Finally, sdr-radio is capable of listening to up to 6 signals in the same chunk of visible spectrum at a time. Many users prefer to use Linrad as it can be set up to have a very high amount of information density on the screen and it also has an advantage with receiving signals with the E tuner as it can be made it run in a special linearity mode which significantly improves the dynamic range.
Linrad also has some very advanced features not found in most other SDR receivers. Linrad is probably the software most superior in terms of actual signal processing performance. To install Linrad on Windows first download and run the setup-dll installer, and then download and extract the actual Linrad program.
You will need to go through a text based set up at the very beginning. It is similar to SDR in terms of features and simplicity of use. It is essentially the same as Studio1. A fairly feature rich piece of software, although the interface can be a bit clunky and difficult to use at times. Since ShinySDR is controlled via a web interface it can easily be controlled over a network or the internet.
It also has a plugin type development feature which allows demodulators to be easily written and integrated. The current main technical advantage to ShinySDR is that it has a persistent waterfall, meaning that the waterfall can be moved, zoomed and re-tuned without loss of any history like in other SDR software. The WebSDR system allows for multiple public users to connect to a radio over the internet and tune to various frequencies.
WebRadio is currently functional but still under development. Seems to be more developed and active than WebRadio.
There is an active list of OpenWebRX receivers listed at sdr. There is a free restricted trial version and the full version can be bought from the Google Play store.
Android app similar to SDR Touch. Still under heavy development. Available for a small price on the Google Play store, or for free from the GitHub. QtRadio is an open source SDR receiver that is based on a client-server architecture from the ground up.
It is designed so that multiple clients can connect to a single server. A browser based SDR client. Is efficient because it only sends the filtered narrowband channels and the waterfall pixels instead of the entire IQ data. Has some other intteresting features too like multiple demodulators, history browsing, pluggable demodulators, improved squelch, histogram, autotune and scanning features.
Mostly seems to be a proof of concept. Have some interesting features though, like waterfall history replay. Frequency counter based on the microphone input. Counts when the input rises or falls past a set level and converts into into frequency or a time period.
Results depend on your device and its hardware. If you just want to Shortwave Radio Schedules This app provides schedules and frequencies for shortwave radio broadcasts throughout the world. Information is also included on some utility stations, Firedrake jammer etc. Information is This driver could be used by third party applications to implement AIS Please provide the ad click URL, if possible:.
