Results on high-frequency waves generated by the PICPAB (Phenomena Induced by Charged Particle Beams) experiment flown on the Spacelab-1 shuttle mission are presented. This experiment comprised both electron and ion accelerators of a few keV energy associated with plasma and wave analysers. The paper presents detailed analysis of the numerous wave spectra obtained in different plasma conditions and different attitudes with respect to the spacecraft velocity vector and the earth magnetic field. The observations are compared to previous results obtained in similar conditions and they are discussed in the frame of various beam-plasma interactions models. The main features are electron cyclotron harmonics which appear modulated in amplitude with maxima occurring near the harmonics of the upper hybrid resonance. An interaction between the return flux electrons and the ambient plasma is thought to have generated the first cyclotron harmonics close to f(uh) and, after nonlinear saturation and trapping processes, the entire spectrum.
