Software-defined radio SDR is a radiocommunication system where omponents that have been traditionally implemented in hardware e. While the concept of SDR is not new, the rapidly evolving capabilities of digital electronics render practical many processes which were once only theoretically possible. A basic SDR system may consist of a personal computer equipped with a sound card, or other analog-to-digital converter, preceded by some form of RF front end. Significant amounts of signal processing are handed over to the general-purpose processor, rather than being done in special-purpose hardware electronic circuits. Such a design produces a radio which can receive and transmit widely different radio protocols sometimes referred to as waveforms based solely on the software used. SDR technology makes it possible that all listeners tune independently, and thus listen to different signals; this is in contrast to the many classical receivers that are already available via the internet. WebSDR was first conceived as a means to make the 25 m radio telescope at Dwingeloo available to many radio amateurs for EME reception.

Over websites allow you to listen to ham radio online. There are two main " flavors " of technology offering this free service. I recommend the Firefox browser instead. With its unrestricted autoplay of sound, it will let you listen to stations on a WebSDR system. In addition, Firefox is the most secure of all browsers. The links below will actually take you to sites where you can listen to amateur radio communicating with each other around the world. The "live" links will let you hear ham radio operators using every imaginable mode of communication The list of modes is nearly endless because new ones are experimented with regularly. The "dead" links have been left in their inactive state to let you know that they might be reactivated by their respective owner. When that becomes the case, I will reactivate the links and you will have access to these reactivated resources.

You can tune in shortwave or mediumwave radio around the world right now with these lists! When the SDR renders in your browser, it will be on the frequency and in the mode you selected, also with a consistent and reasonable filter bandpass for either single sideband or AM. Remember, though, that the map presents a full set, with both good and not-so-good servers plotted. The software defined radio servers listed here have been selected for their reception quality. Performance and coverage vary depending on hardware, internet bandwidth, and radio conditions at individual sites. This is not an exhastive list, as servers are excluded for low SNR. The list updates automatically, so be sure to bookmark it and come back often! During peak operating periods, it may be difficult or impossible to use some of the sites.

These receivers are also part of a TDOA Time Direction of Arrival network that allow the approximate locations of received signals to be determined. Join us on Facebook! The orientation of its antenna favors the Eastern United States which means that the main lobe for DX is oriented toward South Africa, and toward Australia and New Zealand via long path. Western U.

In order to test a preliminary version of the software without using the 25m dish, a shortwave WebSDR was set up on Christmas Eve at the radio club of the University of Twente. Featured Project: Automatic computer audio muting for your HF transceiver. These receivers are using the excellent antenna system on site to receive, decode and contribute WSPR spots and forward that information to the WSPRNET link web site where the results are aggregated and made publicly available.

The results of this may be analyzed to discern band openings, the influences of the sun's activity, lightning static - and perhaps a few other things related to HF propagation and the Earth's geomagnetic field.
