Abstract
This report presents preliminary results of daily observations, over 60 and 100 days, of a complete, flux-limited sample of radio sources with flat sp ectra. The existence of flicker up to 21.7 GHz was confirmed, for sources w ith flat spectra, on a time-scale of 4 days. A model explaining the flux de nsity variations of the unique radio source 0524+034, on long and short tim e-scales, by an intrinsic mechanism is proposed.
