The KiwiSDR is a software-defined radio that attaches to a Seeed BeagleBone Green (BBG) embedded computer. It is available as the board alone or a more complete version including BBG, GPS antenna and enclosure with the software pre-installed on the BBG.
The Kiwi is different from other SDRs. It is a standalone device that attaches to your local network and is optionally accessed through the Internet. A browser is used to connect to the user interface. Most other SDRs generate raw IQ data and need to be connected directly to a PC or laptop running OS-specific, installed software.
Today's technology allows us to build radio receivers that sample radio signals and process them on a PC or an embedded system. Similarly, transmitters can be built that generate the RF signal digitally, then convert it to analog. Software Defined Radio (SDR) refers to the technologies that make these exciting things possible.
On sdr.hu, you can find SDR receivers that amateur radio operators shared, so you can listen to radio signals without even having to buy any SDR hardware! In fact, amateur radio is a great thing and also lets you experiment with transmitting on the air, by using various frequency bands and modulations.
This is my own SDR located at my QTH in the village of Stibbington.
Comparing different SDR stations from around the UK is great fun and very useful for checking out the band conditions or the performance of your own antenna. Itís a very useful tool. If I have an Internet connection I have access to my Kiwi-SDR even on my IPhone while out mobile.
The receive audio maybe not as good as the Derby SDR type of interface or as simple to use but it does offer more features. The Kiwi-SDR interface does have a 10 KHz to 30 MHz band spread in one view which is very impressive.
I spend most of my radio time operating on the lower bands and my active loop and my Kiwi SDR does make the 80 meter and 160 metre band a pleasure to listen to.
I share my SDR on line and anyone can listen and tune to any part of the HF spectrum between 10 kHz & 30 MHz. The loop is very broad band and works very well for general coverage across many bands.
