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

These receivers are also part of a TDOA Time Direction of Arrival network that allow the approximate locations of received signals to be determined. Stop being driven crazy by the echo and eliminate the need to manually mute the WebSDR audio when you transmit!

After further development, its existence was publicly announced in April Interest for the project has been large since then, and many amateurs worldwide have expressed an interest in setting up their own WebSDR server. Find out how to donate! Many of these volunteers are members of other local amateur radio clubs, but the Northern Utah WebSDR itself is not associated with any of these clubs. 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.

Once you get the hang of the waterfall display , you can easily spot a SSB signal for instance and slide over to listen in.
