KiwiSDR is a software-defined radio (SDR) covering shortwave, the longwave & AM broadcast bands, various utility stations, and amateur radio transmissions, world-wide, in the spectrum from 10 kHz to 30 MHz. The KiwiSDR is a custom circuit board (cape) you connect to the BeagleBone GreenorBeagleBone Black computer. You simply add an antenna, power supply and network connection. The KiwiSDR is available in two versions: the cape alone and a more complete version including BBG, enclosure and GPS antenna. Both versions include software supplied on a micro-SD card.
An HTML5-capable browser and internet connection will let you listen to a public KiwiSDR anywhere in the world. Up to four people can listen simultaneously to one radio — each listener tunes independently.

100% Open Source / Open Hardware.
Browser-based interface allowing four simultaneous user web connections.
Each connection tunes an independent receiver channel over the entire spectrum.
Waterfall tunes independently of audio and includes zooming and panning.
Multi-channel, parallel DDC design using bit-width optimized CIC filters.
Good performance at VLF/LF since we personally spend time monitoring those frequencies.
Automatic frequency calibration via received GPS timing.
Easy hardware and software setup. Browser-based configuration interface.
Extension interface for adding decoders and utilities.
