KiwiSDR Kit: Wide-band SDR + GPS Antenna for the BeagleBone Black and BeagleBone Green
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.
PRODUCT DETAILS
Note
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.
Key Features
-
100% Open Source / Open Hardware.
-
Compatible with Beaglebone Green/BeagleBone Black
-
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.
Description
Will you enjoy quickly zooming in and out of bands, finding interesting stations, and listening to someone else’s bands ? KiwiSDR kit can make all of these become a fact.
What is KiwiSDR ?
In short, KiwiSDR is a custom circuit board (cape alone) you connect to the BeagleBone Green or BeagleBone Black computer, an embedded Linux development board that is similar to a Raspberry Pi. You simply add an antenna, power supply and network connection.
To be more specific, KiwiSDR is a Linux-based, stand-alone software-defined radio capable of receiving from DC to at least 30 MHz using a variety of modes (SSB, AM, FM, Synchronous AM) and has several "extensions" that allow reception of several digital modes - including CW, RTTY, and WSPR - as well as provide a means of viewing FAX transmissions and SSTV. It also includes a provision for TDOA (Time Difference of Arrival) determination of transmitter location in conjunction with other similarly-equipped receivers.
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.

What makes it special ?
KiwiSDR makes direct access to SDR possible. It connects to your home internet network instead of your PC, which enables you to access it from any computing device via a web browser.
Thus, the on board FPGA and Beaglebone’ s CPU, instead of your PC, will perform all the computing. What your PC can see is only the compressed audio and waterfall stream. You do not need a powerful computer to run SDR, actually, a mobile phone or tablet will be qualified.
KiwiSDR does not have a front panel, but rather it is entirely used via a web interface, which makes it used remotely, by several people, simultaneously - each person getting their own virtual receiver that they may independently tune.
Application
-
Setting up a remote receiver in a good noise free location
-
Helping hams give themselves propagation reports by accessing a remote KiwiSDR while they are TXing
-
Listening to shortwave stations, monitoring WSPR or WEFAX channels, education, crowd sourced science experiments and more
