PS I just had a look at your project file “saq opname.aup3” and unfortunately I can’t see any valid VLF there setting the waveform to spectral view. Looks like something has gone wrong and you are not recording VLF, should be frequencies up to about 21KHz. The spectral view should show several VLF stations with SAQ at 17.2KHZ but I don’t see any VLF stations in your file on the spectral view.
