The High Frequency Active Auroral Research Program (HAARP) ionospheric heating facility in Alaska (L = 4.9) is able to generate electromagnetic radiation in the 500 Hz - 10 kHz (ELF/VLF) frequency range. In an on-going experiment the HAARP facility is used to inject ELF/VLF waves into the magnetosphere to trigger wave-particle interactions with radiation belt electrons that result in the non-linear amplification of the wave, known as the coherent whistler mode instability. The conditions associated with observations of magnetospherically amplified signals known as ‘echoes’ are examined. Conditions enabling the propagation of the HAARP generated ELF/VLF signals along field aligned paths are found to be key dependencies. The assessment is based on geomagnetic indices and experiments involving ELF/VLF generation using different HF beam positions. Since HAARP signals are found to be injected primarily very close to the heating facility, the position of the plasmapause is a key parameter in echo observations.
