Fausto,

I believe the Luxembourg effect is a form of cross-modulation occurring in the ionosphere when there is a high power transmitting station somewhere on the path between the receiving and transmitting stations, but the signal from the interfering station is not strong enough to overload the receiver.

Could one of our propagation experts provide a more detailed explanation please?

Is this a Luxembourg effect ?
First 40 sec i listen at 137 KHz, after i tune at 153 KHz on the original transmission.
RX is a Perseus SDR with a 200 KHz low pass filter at the input for eliminate MF overload.
The word "trial" every tot second is because i have install a trial version of VAC software.
