Investigating the crossing of the southern source region of Saturn Kilometric Radiation (SKR) by the Cassini spacecraft in late 2008, we review the intrinsic properties of SKR waves and their evolution with propagation through the kronian high-latitude plasma. In particular, we identify SKR magneto-ionic modes and estimate the electron/wave energy conversion efficiency thanks to in situ and remote observations. Then, we focus on the unusual locus of radio sources, illustrating an enhanced auroral activity. The beaming pattern is derived from different techniques for local and distant radio sources, and shows that kilometric waves are generally emitted at large angles with respect to the local magnetic field vector. Finally, we show that the SKR polarization is elliptical at the source, but becomes gradually circular along the ray path. The SKR polarization transfer is satisfactorily described in the frame of wave propagation in a cold plasma and conditions of weak mode coupling. SKR characteristics are analyzed comparatively to other equivalent auroral planetary radio emissions.
