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.

Got the KiwiSDR up and running with no problems initially but after running for a few days the BB Green network interface has died. Link LED doesn't light, with no link established. No amount of power cycling or software reload fixes it. Have tested network switch and cable, along with power supply voltages. Have since removed KiwiSDR and installed on a spare BB Black I had, all works fine with it. The supplied BB Green appears to be faulty. How do I get a replacement?

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)Answer by: admin on 2018-12-18 02:32:01

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.Answer by: admin on 2018-12-18 02:21:28

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.

Like to order a complete KIT - When will complete Kit be available - Can I simply get KiwiSDR now and just plug in BBG board from Amazon and find a GPS Antenna Mike ava622(at)verizon(dot)netQuestion by: admin on 2018-12-18 02:20:56
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, KiwiSDRAnswer by: admin on 2018-12-18 02:20:56
Is a power supply required for simple HF listening, or is the voltage from the usb enough? Also, I/O can be through ethernet or USB, correct?Question by: admin on 2018-12-18 02:20:21
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-overloadAnswer by: admin on 2018-12-18 02:20:21
For the moment I have given up as I can't get rid of them. They are still there when I have removed antenna and all my peripheral circuitry, leaving just the power cable (with large ferrite ring), and the CAT6 cable (with FT240-31 rings at either end) with the antenna input shorted out. In fact I surmise that the unwanted signals come directly from the IP network communication. Has any one else seen this? And better still has anyone found a way around the situation/problem??Question by: admin on 2018-12-18 02:19:36
