Abstract : The validity of the synchrotron expanding source model for quasars as proposed by Shklovskii, Kellerman and van der Laan is tested, using observations of the radio emission from four quasistellar radio sources. The time dependence of the recorded variations of radio emission in the range from 3.3 mm to approximately 6 cm, taken during the period from 1965 to late 1969 from QSS 3C84, 3C120, 3C273 and 3C454.3 is compared to the time dependence of the variations predicted by the proposed model. Correlation between observed variations and predicted variations is excellent in over 85% of the cases tested. (Author)
