英文說明:
NDBfinder detects NDB transmissions using the sound card in your PC.
You need a suitable LF/MF band radio receiver tuned to an appropriate
frequency in the navigational beacon band. The program processes the
audio signal from the receiver and shows you signals that are hidden
in the noise. Signal View - displays the raw audio signals on your PC
screen in a diagnostic display which helps you to set up the
connection and the soundcard. Spectrum View - displays a scrolling
spectrum of the received audio signal frequencies on your PC screen.
You see an immediate display of the mose code identification if the
beacon is received with good strength. By default the display covers
0-3kHz but other audio frequency ranges can be specified by the user.
Spectral Density display - shows the overall Spectral Density of the
accumulated data. On this display, you can discover morse code
identifications that are too weak to be seen on the Spectrum View.
Periodicity display - shows an analysis of any periodicities in the
pattern in the chosen audio frequency. If there is a morse code
identification buried in the noise at the selected audio frequency,
its periodicity will be betrayed by a spike in this display.
Integrated display - shows the result of a boxcar integration of the
signal at the chosen frequency and with the specified period. If the
signal is processed for several minutes, huge improvements in the
signal-to-noise ratio can be acheived. This can make the difference
between a signal being undetectable and being easy to identify.
Beacon Identification - The program can decode and display the
three-letter identification of the signal that you have detected. Log
file - The program can automatically save the identification, the
audio heterodyne, and the ident period to a log file. Playback - The
program can play back the audio resulting from addition of multiple
idents so that the signal can be identified aurally. Script - The
program can execute a command script to allow fully automated
monitoring and surveying.
