Listen to amateur radio online with KiwiSDR

An SDR (Software Defined Radio) turns real radio signals — shortwave (HF), medium wave (MW) and long wave (LW) — into audio you can hear in the browser. We gather verified public KiwiSDR receivers: a world map, a country directory (including Latin America) and direct links to live antennas, with nothing to install and no license needed just to listen.

Frequently asked questions

What is KiwiSDR?

KiwiSDR is a web-accessible software-defined radio (SDR) receiver. Anyone can open a public receiver URL and tune HF, MW or LW bands from another amateur’s physical antenna, in real time.

Do I need an amateur radio license to listen?

No. Listening to public KiwiSDR receivers in the browser does not require a license. A license is needed to transmit; here you only hear signals captured by publicly shared antennas.

What’s the difference between HF, MW and LW?

LW (long wave) and MW (medium wave) are often used for local or regional AM stations. HF (shortwave) travels farther and can bring international broadcasters, utilities and amateurs depending on daily propagation.

Why are some receivers offline?

KiwiSDRs are run by volunteers: hardware may power down, fill up with users or lose connectivity. Our directory prioritizes receivers that responded recently; online status is checked when the page loads.

Are there KiwiSDR receivers in Latin America?

Yes, whenever public antennas are online in Brazil, Mexico, Colombia, Argentina, Peru or other countries in the region. They appear on the map and in the directory grouped by country alongside Spain and the rest of Europe.
