IFSK Tracker

The IFSKTracker application allows you to plot the signal-to-noise level of a narrow-band IFSK signal versus distance or time. It is intended for the analysis of geographically extended radio paths or for estimating the passage of radio signals depending on the time of day. The principle of operation is based on the reception of a beacon signal emitting a reference modulated IFSK signal. A car (or any other vehicle) with a GPS receiver on board, having fixed the starting point, sets off with a connected radio tuned to the frequency of the beacon. A low-frequency signal with a set sound frequency and sideband (in the case of SSB) is fed to the input of an audio card (smartphone). Activation and deactivation of the recording occurs by pressing the corresponding button in the program menu. At the end of the recording, the data is saved in a separate folder
