I love to use SDR Console with my FM-dxing and record also whole night and later in the morning check if anything interesting was going on. I have been using Playback Navigator to my recordings because my old i5 does not have enough power to handle large files with Analyzer. Playback Navigator in Waterfall/Bitmap mode works fine but I have been wondering what defines the time gap between two time marks. Sometimes it is only two minutes, sometimes six or twelve or even bigger. It has something to do with how large the recording is and what is the chosen intervall.
