Accès gratuit mondial aux SDR (via la communauté KiwiSDR)

Accédez à tous les récepteurs Kiwi SDR en direct dans le monde entier. Consultez la liste des radios partagées par les récepteurs du monde entier. Il y en a entre 800 et plus de 2 000, selon les créneaux horaires.

Il vous suffit de saisir votre localisation, la bande radiofréquence souhaitée, d'effectuer une recherche textuelle ou de consulter la carte du monde pour voir et entendre ce que reçoivent les membres de la communauté locale, comme si vous y étiez. Aucun matériel n'est requis, ni inscription, ni connexion (certains diffuseurs vous demanderont simplement une pièce d'identité). Bien entendu, certaines zones de guerre ou aéroportuaires sont plus fréquentées que d'autres.

The KiwiSDR community provides here an online platform that offers worldwide live access to thousands of KiwiSDR receivers deployed by users across various locations. This network of interconnected SDR receivers streams real-time radio signals via the internet, allowing individuals to explore global radio activities from their computers or mobile devices without needing to own or operate hardware themselves. The online SDR initiative enables unique opportunities for global signal monitoring, propagation studies, and hobbyist listening, connecting radio enthusiasts in an interactive, collaboratif environment while expanding the reach and capabilities of software-defined radio technology.

Si vous souhaitez devenir radioamateur, OSINTRF, c'est la première étape d'un grand voyage. Un excellent exemple de projet open source et de partage communautaire.

Pour info, la partie matérielle du projet : the KiwiSDR project is an innovative open-source initiative focused on developing a software-defined radio (SDR) receiver that is accessible, affordable, and versatile. Based on a compact hardware device equipped with a high-performance analog-to-digital converter and a powerful microcontrôleur, KiwiSDR enables the reception of a wide range of radio frequencies, from long wave to shortwave bands. Its design emphasizes ease of use and integration with web technologies, allowing users to control and listen to radio signals remotely through a browser interface. This project fosters experimentation, education, and amateur radio activities, making sophisticated SDR technology widely available to enthusiasts and researchers around the globe.

Receiver hardware: The public list indexes receivers built on KiwiSDR, a wideband board covering 10 kHz to 30 MHz with a 14-bit ADC (LTC2248, as described in a 2017 review). Each owner hosts a unit and shares it.Receiver hardware: A set of shared receivers listed at websdr.org, run by radio clubs, individuals and institutions on standardized WebSDR server software. Hardware varies from site to site.
Frequency coverage: Mostly the whole LF, MF and HF range from a single unit. VHF and above is not covered by the KiwiSDR board itself.Frequency coverage: Most stations cover a limited range, such as selected amateur bands. The best known one, at the University of Twente, covers 0 to 30 MHz.
Concurrent users: A single KiwiSDR serves a small number of listeners at once (up to 4 in the 2017 review), each with an independent tuning. This is a real constraint on busy receivers.Concurrent users: One receiver can serve hundreds of users at once through the browser, which suits popular stations.
Selection and discovery: The list has a world map, search by place or band, and a text filter, so you can pick the receiver closest to the signal of interest. This helps propagation and monitoring work.Selection and discovery: Stations are grouped on a list page. There is no single common map interface across all receivers.
Cost and openness: Listening is free without registration. The KiwiSDR project is open source and hosts are volunteers. A unit was sold as a complete kit in the 2017 review, so check the current price.Cost and openness: Listening is free. The server software is shared with station operators, but this page does not confirm its licence terms.

Sujets abordés : SDR, radio logicielle, signaux radio en temps réel, KiwiSDR, plateforme en ligne, surveillance des signaux, études de propagation, projet open-source, partage communautaire, convertisseur analogique-numérique, microcontrôleur, télécommande, interface navigateur, radioamateur, bandes RF, activités radio mondiales et environnement interactif.
