Abstract : We review experiments in ionospheric modification and long distance propagation performed at the HAARP facility. Most experiments were in bistatic configuration with the WAVES receiver on the NASA/WIND satellite. Initial experiments showed scintillation-like variations in low frequency propagation through the earth's ionosphere. A HAARP-HIPAS transmission experiment set up a spatial interference pattern measured at WIND. The Kodiak SuperDARN radar scanned the modified region above HAARP and observed the growth of ionospheric irregularities. Recently, lunar echoes at 8 MHz were detected by WIND. The experiments at HAARP will extend to nonlinear regimes as power levels increase.
