Abstract
Experimental observations of whistlers carried out in July, 2011, at the Paratunka observatory (53.02° N, 158.65° E; L = 2.3) and coinciding in time with experiments in the scope of the HAARP project (62.30° N, 145.30° W; L = 4.2) made it possible to discover their nonstandard shape, which is most probably caused by amplitude-modulated electromagnetic pulses with a duration of about 1 s and a basic frequency of ≈ 1.1 kHz.
