Recently our technique of waveform observation has become perfect by using the supersonic delay line with 250 micro-seconds delay time. Employing waveforms newly observed, the author tried to deduce the relation between the characteristic of frequency spectrum and the distance of propagation of atmospherics, and obtained following results. (1) Phase-frequency spectrum of smooth daytime type waveform seems to correspond to the effect of propagation distance. (2) Amplitude-frequency spectrum of nighttime regular peak type waveform is characterised by a minimum component around 2 kc/s. (3) Frequency spectrum of nighttime quasi-sinusoidal type waveform shows comparatively similar characterrstic to the smooth daytime type waveform.
