KiwiSDR: BeagleBone Software-defined Radio (SDR) with GPS
What is KiwiSDR?
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 you connect to an inexpensive BeagleBone Black or Green computer. Add an antenna, power supply, internet connection, then install the software package to be running in minutes.
