KiwiSDR Kit SKU 110060490 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. Description 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 GreenorBeagleBone 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.

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. Specification SDR covers the 10 kHz to 30 MHz (VLF-HF) spectrum. Web interface based on OpenWebRX from András Retzler, HA7ILM. Demodulation modes: AM, AMN, LSB, USB, CW, CWN, NBFM. Extensions at present: WSPR viewer/decoder, IQ display, Loran-C viewer. RF antenna connector: SMA and terminal block.
