Hello Markus,

Here similarly there was a powerful signal at 9 khz. I have tried to change 
value Sample Rate,
have established 96000, and this signal has disappeared. All "present" 
VLF-stations remained on the places.

Hello Mike,

this is most likely intermodulation from the 9 kHz raster in the European MF and LF broadcast bands. Viewed in detail, it is not a single carrier but a conglomerate of closely spaced lines, probably due to non precise BC carrier frequencies.

Best 73,

Markus, DF6NM
