                         Spectroscope (BSS, Sawant, H.S., Subramanian, K.R., Faria, C., et 
                         al. Brazilian Solar Spectroscope (BSS). Solar Phys. 200, 167-176, 
                         2001) with high time (10-1000 ms) and frequency (1-10 MHz) 
                         resolution is in regular operation since April, 1998, at the 
                         National Space Research Institute (INPE) at Sao Jose dos Campos, 
                         Brazil. The BSS has now been upgraded with a new digital data 
                         acquisition and data processing system. The new version of the BSS 
                         has improved the observational possibilities with the capability 
                         to record up to 200 frequency channels available in the selectable 
                         frequency range 950-2500 MHz. The GPS receiver permits the 
                         acquisition of data with time accuracy in the order of 0.1 ins. 
                         The software system of the BSS is composed by two distinct 
                         modules: the first, data acquisition system provides a flexible 
                         Graphical User Interface (GUI) that allows one to choose the 
                         observational parameters. The second module is the real time 
                         visualization system that permits real time visualization of the 
                         observed dynamic spectrum and additionally allows procedures for 
                         visualization and preliminary analysis of the recorded solar 
                         spectra. Using the new visualization system, we have realized two 
                         new types of dm-radio fine structures: narrow band type Ill bursts 
                         with positive as well as negative group frequency drift and dots 
                         emissions arranged in zebra-like and fiber-like chains. 
                         Furthermore, we have found flare generated fast wave trains 
                         according to their tadpole signature in wavelet power spectra for 
                         a decimetric type IV radio event (June 6, 2000 flare).",
