The observation of active regions with RATAN-600 and the Beijing Astronomical Observatory spectrograph in the decimeter wave band shows an existence of a long-term non-thermal emission of active regions in continual (a halo) and flaring (flares and micro flares) components. The observation-compatible models have been devised specifying the nature of continuum as a radiation originating in the non-linear interaction of plasma waves at the upper-hybrid frequency. ...
