The authors present flux densities of SS 433 at 2695 and 8085 MHz spanning the period July 1979 - December 1985. The variations may be characterized as a clustering of flare events separated by periods of quiescent emission. A harmonic analysis reveals no significant periodicities in either the entire 7 yr data set or in subsets corresponding to active and quiescent time frames. There is, however, broadband power from roughly 50 to 200 days which fades during 1985. Moreover, the authors find that the temporal power distribution of SS 433 at both frequencies strongly resembles 1/f noise. Finally, a comparison with 408 MHz data (Bonsignori-Facondi et al., 1986) shows variations in the light curves to lag those at 2695 and 8085 MHz by approximately 4 days.
