Selected time series of the separated radio dynamic spectrum from panel 1a (Fig. 2) and the wavelet tadpole patterns with a characteristic period P ≈ 0.7  s. These time series (9:34:56−9:35:01 UT) observed at frequencies 4887 (panel a)), 5579 (panel b)), 5957 (panel c)), and 6073 MHz (panel d)) show their peak maxima (red arrows) equal to the maxima of the wavelet tadpole heads. The frequency drift of these head maxima is 2892 MHz s-1.
