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 Green or BeagleBone 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.
Try it right now! Listen to KiwiSDR registered on the sdr.hu website.
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.

According to estimates, this product will arrive in mid-April.
Hi Ron. If you purchased from Seeed please email email@example.com to get a replacement. Otherwise contact the distributor you purchased from. There seem to have been a bunch of BBGs produced with Ethernet PHY failures. John (firstname.lastname@example.org)
Thank you Eric.
After you've made a purchase you'll see a "review" button on the order history page. I think you also get an email asking for a review.
VA3ROM, sorry I've only seen your question just now (July 27). I don't get a notification for these unfortunately. There _should_ have been a printed "quick start" instruction sheet in the box with enclosure assembly information. You can find it online here: http://kiwisdr.com/quickstart/quickstart.pdf Please email email@example.com with any questions. Best regards, John, ZL/KF6VO, KiwiSDR
Sorry, I am only seeing this question now, one month later. Actually, the SE4150L is the GPS front-end chip used on the Kiwi board. For a compatible GPS antenna you want one that has an SMA-M connector, works at 3.3V, at least 27 dB of gain and no more than 3m cable length if it is using small diameter coax to avoid excessive signal loss. One example is the Abracon APAMP-111 available from Mouser in the USA. Please see the kiwisdr.com website for more details. Regards, John, KiwiSDR
Hi Dan. Yes, it is possible you will need an HPF. Depends on how strong your local AM BCB signals are. See here: http://kiwisdr.com/quickstart/index.html#id-overload
