Listen Anywhere in the World

KiwiSDR is a software-defined radio that covers shortwave and longwave signals, AM broadcast bands, utility stations, and amateur radio transmissions in the spectrum from 10 kHz to 30 MHz. It features a custom circuit board that connects to the Beaglebone Green or Beaglebone Black—all you need to supply is an antenna (included), power supply, and network connection and you can listen from anywhere in the world. Like all Seeed products, it’s 100-percent open source and ready for customization.

Note: The drop price listed is the MAP (Minimum Advertised Price) set by the manufacturer. Massdrop is not allowed to advertise a lower price than the MAP price. At checkout you will be able to activate a $80 discount on this drop.

4 Connections, Easy Assembly

The KiwiSDR allows up to four simultaneous user web connections, so four people can listen on the same device independently of one another. It automatically calibrates frequency thanks to received GPS timing. And with easy hardware and software assembly, it’s great for tinkerers, developers, and anyone interested in exploring their creativity.
