Abstract Decimetric Solar Radio Spectroscope has been put into operation since March 1991 at São José dos Campos, Brazil. Presently, it is operating over frequency range of (1.6 ± 0.1) GHz, with time resolution of 100 ms and frequency resolution of (0.3–3) MHz, in conjunction with a 9 m diameter polar mounted antenna. The dynamic spectra are recorded on 35 mm film, while 20 frequencies each separated by 10 MHz are digitized with time resolution of 100 ms. So far, various types of bursts have been observed by this system. Morphological studies of these bursts are presented. Particularly interesting are reverse slope (RS) type III bursts. Soon this system will start operating over a frequency range of (0.2–2.5) GHz, simultaneously in two circular polarizations. Flexibility of this system permits to select desired frequency range with resolution in time of (1–250) ms and in frequency of (0.1–3) MHz.
