But is the another phenomenon. The Luxembourg effect.
The dipole radiate the doubled frequency.

That is NOT the Luxembourg Effect. The Luxembourg effect is/was cross
modulation of 2 stations due to non-linearities in the atmosphere.

It is an explanation.
The Luxembourg effect WAS the receiving of LW from Luxembourg mast on the
MW
receivers tuned to the doubled frequency..

No it wasn't, it was receiving the audio from Radio Luxembourg, whilst
tuned to and receiving another MW station (not at twice the frequency).

In 1933 newspaper was wrote that exactly twice.

And like many of your other ancient references, it was wrong.

There is no relationship to the frequencies.

That is you heard both stations simultaneously. This is nothing to do with
harmonics at twice the frequency, it is a phenomenon known as cross
modulation.

Is the cross modulation if the LW are from the monopole antenna?

Cross modulation has absolutely nothing to do with antennas.

It is an effect caused by a perturbed region of the ionosphere far from
the antennas.

You are a babbling idiot.
