It`s the so-called Luxembourg Effect, ionospheric cross-modulation. Search on that for all about it. 73, Glenn Hauser

Even when France Inter audio was


present on 162kHz, I could always hear low
level audio below from other French language longwave
stations. I had
assumed this was due to cross-modulation in the receiver,
but now see
others are observing the same effect. Do we think it is
reverse
intermodulation in the Allouis transmitter?

The effect is also quite good to hear on the WEB-SDR in Twente.
This receiver is in an ideal position for this constellation.
Here you can see the way of the waves on a map:
