J1128+592 is a compact radio quasar and, as ~ 30% of flat spectrum radio sources, shows fast variations in the cm-wavelength regime on time-scales of an hour to few days. Such phenomenon is often explained by scattering of radio waves in the turbulent, ionized interstellar matter of the Milky Way. Regular monitoring observations of J1128+592 performed by the Effelsberg 100-meter and the Urumqi 25-meter radio telescope during the last four years confirmed this, since a seasonal cycle of the variability time-scale was revealed. This effect is one of the most convincing argument in favor of the interstellar scattering induced fast radio variations in blazars. Multi-epoch, multi-frequency observations made by the Very Long Baseline Array (VLBA) together with the annual modulation model enabled us to determine a lower limit of the distance of the screen responsible for the rapid variability. Additionally, it revealed source-intrinsic-change, which affected the variability pattern.
