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.
