Abstract Radio observations of 33 compact extragalactic sources, obtained at 2.695 and 8.085 GHz using the Green Bank interferometer as part of a regular monitoring program during 1979-1985, are reported. The calibration and data-analysis procedures are described, and the results are presented in extensive tables and graphs. Although the light-curve variations are found to be dominated by intrinsic changes, some refractive interstellar scintillation effects and anomalous light-curve dropouts (tentatively attributed to occultation events) are also observed. An unexpected linear dependence of the rms variation at 2.695 GHz compared with that at 8.085 GHz was found, indicating that the onset and evolution of flares must be similar in different sources.
