A Software-defined radio (SDR) is a radio communication system where components that have been traditionally implemented in hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a personal computer or embedded system (still with significant hardware support).

We are suggesting this SDR for use with the Raspberry Pi WeatherSense (WeatherRack2) kits is based on the powerful RTL2832U and R820T tuner, it can tune into signals from 24MHz to 1850MHz.
SwitchDoc Labs has written drivers for the WeatherSense weather sensors and supplies the drivers to the community open source. These are all provided in our pre-built SD Card image.
