Luxemburg–Gorky effect

As Luxembourg effect is known in radio technology a kind of ionospheric cross-modulation between (at least) two transmitters, especially in the long and medium wave. The Luxembourg effect shows itself in that the broadcast program of a long or medium wave transmitter is weak be heard in the background of the other.

The Luxembourg effect got its name from the fact that after the commissioning of the strong long-wave transmitter of Radio Luxembourg in the 1930s when receiving the Swiss medium wave transmitter Beromunster sometimes the program of Radio Luxembourg was heard in the background, even though both sender completely different frequencies - even different bands - used. The effect was first described in 1934 by Victor Albert Bailey and David Forbes Martyn.

The Luxembourg effect plays a role in some carried out with HAARP experiments.
