Radio Astronomy Software Defined Radio (Rasdr)
Where can I get it? Of the two completed SDR receiver (hardware) designs based on the RASDR concept (wide-bandwidth, Windows-compatible, documented SDR for Radio Astronomy), only RASDR4 is now marketed.

Thirty years later, another physicist, Henrich Hertz, demonstrated radio transmission and reception and initiated an era of Hardware-Defined Receivers (HDR). User-provided data specifies center frequency, bandwidth, and some initial values used to choose optimal operational range of the Lime femtocell ship. RASDRViewer software runs in a Windows environment and performs receiver control, FFT analysis, spectrum averaging, power monitoring and other functions.
