Annotation. The paper describes the principle of operation of the modernized system of one- and two-way comparisons and transmission of time scales (SOTCT-M). The results of the development of (SOTCT-M). and the results of metrological studies of the system are presented. The results of evaluating the temperature coefficients affecting the hardware delay are presented. The error in the transmission of time scales was estimated, and the ADEV added during the transmission of frequency signals was measured.

Key words: synchronization of time scales, FOL, transmission of reference signals.
