Radio emissions and hard X-ray are a signature of energetic electrons interacting with the surrounding plasma during solar flares. The GOES X4 flare on 03 November 2003 was observed at metric/decimetric wavelengths by the Nancay Radioheliograph (NRH) and at centimetric/millimetric wavelengths by radio instruments by the Institute of Applied Physics (University of Bern). It was simultaneously observed by the RHESSI experiment in the hard X-ray range. The time profile of the centimetric/millimetric emissions show two main parts: the impulsive one lasting about three minutes and a long duration emission separated in time by four minutes. A CME and a type II emission are observed by the Zurich spectrometer between the impulsive part and the long duration continuum and might suggest that this emission is responsible of the differences in the characteristics of energetic electrons in both parts of the events. Spectral analysis of the radio and hard X-ray emissions will be performed in order to investigate quantitatively these differences and the link between Hard X-ray emissions and centimetric/millimetric emissions.
