kiwiSDR - SDR Multiband Receiver

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 includes:

- KiwiSDR Receiver

- Beagle Bone Green 

-  enclosure

- GPS antenna

- software on a micro-SD card

- printed documentation with first steps

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.

Features

• 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.
