Results of observations of the solar sporadic radio emission in decameter range are presented. These observations were carried out at UTR-2 radio telescope with 60-channel spectrometer and DSP (Digital Spectral Polarimeter) last years. Particular attention is devoted to such components of sporadic radio emission as Type III bursts, Type II bursts, “drift pair” bursts. New properties of these bursts, which distinguished for decameter band, are noted. They are as follows: – fine structure of Type III bursts unobserved before at other frequencies; – first discovered fine structure of Type II bursts in the form of small duration sub bursts with positive and negative frequency drift; – wavelike movement of Type II burst backbone with herringbone structure; – difference of frequency drift rates of “drift pair” bursts with positive and negative rates.
