The previously reported Trimpi effect involves observation of amplitude perturbations in subionospherically propagating fixed-frequency VLF signals. The preturbations are coincident in time with magnetospherically propagating whistlers, and it has been inferred that the whistlers drive energetic precipitation of E>100 keV in a manner such that a localized increase in ionization occurs near 80-km altitude in the nighttime earth-ionosphere waveguide. In the present work, VLF broadband, analog chart and DF data from Palmer Station, Antarctica (Lapprox.2.3), recorded in 1978 and 1979 are used to investigate additional features of the Trimpi process. Attention was concentrated on perturbation of the signals NSS (21.4 kHz) and NLK (18.6 kHz) that have arrival bearings at Palmer of 352/sup 0/ and 318/sup 0/, respectively.
