Narrow precipitation spikes of energetic electrons observed in the inner zone drift loss cone during the 1968-1970 period by instrumentation on the OV1-14 and OV1-19 satellites are shown to have characteristics which are consistent with pitch angle scattering produced through a resonant interaction with ground-based VLF transmissions. Analysis of the pitch angle distributions indicates that for virtually all of the events the electrons last interacted with the atmosphere in the vicinity of 55¿-62¿ east longitude. The L dependency of the spikes as a function of energy is consistent with scattering by a monochromatic wave. The presumption is that the Russian station UMS, located at 44¿E and operating at a frequency of 16.2 kHz during this period, was responsible for these precipitation events.
