CubicSDR is the software portion of Software Defined Radio. By using hardware that converts RF spectrum into a digital stream we are able to build complex radios to do many types of functions in software instead of traditional hardware. Paired with a supported hardware receiver, you can use CubicSDR to explore the RF world around you. Discover Satellite transmissions, Amateur Radio, Rail, Aeronautical, Shortwave, or any number of possible signals floating through the air.
