Abstract

This report presents preliminary results of daily observations, over 60 and 100 days, ofa complete, flux-limited sample of radio sources with flat spectra. The existence of flicker up to21.7 GHz was confirmed, for sources with flat spectra, on a time-scale of 4 days. A model explainingthe flux density variations of the unique radio source 0524+034, on long and short time-scales, by anintrinsic mechanism is proposed.
