Access all the Kiwi SDR live receivers worldwide. List or view receiver’s shared radios all over the world. 800 to 2000+ of these depending on time slots.

只需输入您想收听的位置、射频频段、进行文本搜索，或者直接查看世界地图，即可收听/观看当地社区成员接收到的信号，仿佛身临其境。无需任何硬件，无需注册，无需登录（部分广播公司可能仅要求您提供身份证明）。当然，某些战区或机场区域的收听人数会比其他地方更多。

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, 协作 environment while expanding the reach and capabilities of software-defined radio technology.

如果你想进入业余无线电领域，开源情报RF，这是漫长征程的第一步。 这是开源项目与社区共享的绝佳范例。

仅供参考，该项目的硬件部分如下： 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 微控制器, 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.

Worldwide SDR Free Access (via KiwiSDR community) compared with WebSDR
全球SDR免费访问（通过KiwiSDR社区）	WebSDR
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.
