To study the nature and origin of the whistling atmospherics we are devising an apparatus which consists of a preamplifier, a main-amplifier, low and high pass filters, a magnetic tape recorder of two elements and a frequency analyser. The whistlers are received by means of a straight amplifier with an available gain of 50-100 db, its input being connected to a vertical antenna and its output to a magnetic tape recorder. The frequency response is limited by filters from 300 c/s to 15 kc/s. Routine observations of this measuring set will be opened from next year.
