Campaign time! Experiments begin in the mid morning 19 February Alaska Standard Time (AKST) and continue intermittently through the evening each day through 22 February.

Luxembourg Broadcast

The first radio modification of the ionosphere occurred in the early 1930s and was an accidental consequence of the new and powerful Radio Luxembourg transmitter. In certain situations, listeners of other weaker broadcast radio stations found that they sometimes heard Radio Luxembourg programming even though it was transmitted on a completely different frequency. Scientists and engineers eventually concluded that signals from powerful Radio Luxembourg and less powerful stations were being mixed in space, that is, through ionosphere modification.

HAARP will transmit a sequence of tones and music using amplitude modulation (AM) on two different radio frequencies (2.7 MHz and 3.3 MHz) in a sort of reproduction of this so-called Luxembourg Effect. If conditions are sufficient and you tune-in to one frequency or the other, you will hear tones and music from both frequencies. The tones and music have been specifically composed to take advantage of the Luxembourg effect.

The Luxembourg broadcast will begin as early as 6 p.m. on 19 and 20 February Alaska Standard Time (AKST) and conclude by 6:40 p.m. In Coordinate Universal Time (UTC), the broadcasts will begin as early as 03:00 on 20 and 21 February and conclude by 03:40. Tune in to 2.7 MHz or 3.3 MHz (2700 KHz or 3300 KHz), or both! The program is approximately 10 minutes in duration and will repeat until 6:40 p.m. AKST or 03:40 UTC.
