Within the frame of the EU-INTAS project "New Frontiers in Decametre Radio Astronomy" research groups of France (Observatoire de Paris-Meudon), Austria (Space Research Institute Graz) and Ukraine (Radioastronomy Institute Kharkov) cooperate in the investigation of Jovian decametric radio observation and analysis of data obtained by simultaneous measurement campaigns using digital spectropolarimeters (DSP) at the radio telescopes Nancay (France) and Kharkov (Ukraine) in combination with a newly developed waveform receiver (WFR) additionally installed at Kharkov. Both devices (DSP and WFR) are fully digital receiving systems with high sensitivity and high spectral resolution. Especially the waveform receiver is capable of retaining the real received waveform of the emission for a time period of up to five seconds.
A general spectral overview will be given on different Io-related radio storms explaining the capabilities of simultaneos high frequency and time resolution observations by almost identical DSPs separated East-West by about 3500 km. At selected periods of time especially for high millisecond burst activity the WFR was put into operation. These data provide the key for further detailed studies on internal structures and phase changes within single millisecond radio bursts.
