NDBfinder allows you to use your PC and soundcard to receive, detect, identify and log NDBs (Non Directional Beacons used for maritime and aeronautical navigation), that would otherwise be too distant or faint to detect.
NDBfinder exploits the fact that almost all navigation beacons send their idents are precisely regular intervals. Using a unique combination of two Fourier Transforms and a Boxcar Integrator, NDBfinder is able to superimpose many successive indents and in doing so it can retrieve signals that are buried in the noise. This makes it possible for NDB DXers to detect beacons far beyond the normal reception range.
