Abstract: The results of long-term monitoring of the sources 3C273, 3C279 and 3C454.3 at 102 MHz–36.8 GHz are presented. Numerical analysis of irregular temporal rows of the integral fluxes allowed us to detect the quasiperiodic constituents of the emission flux variations. The analysis of the parameters of binary black holes in the central regions of non-stationary objects demonstrates that these super-massive objects have an insignificant variation between the sizes of the orbits of partners, and that they are in the stage of evolution different from the time of merging by a period of less than 104 years.
