"BeaconSee analyses the audio signals from your radio, which is tuned to the NCDXF IARU HF beacon network. Using Fast Fourier Transforms, BeaconSee shows you the signal strength received from each of the 18 beacon transmitters as a plot of frequency spectrum against time. You can even detect beacon signals which are too weak to hear. Even if there is some co-channel interference, BeaconSee can sort out the beacons from the noise with its sophisticated fourier signal analysis."
