The spectral and time variability in flux density of the extragalactic source 3С345 during 1965 – 2000 at 4.8, 8, 14.5, 22.2 and 36.8 GHz was analyzed. The long-term variability of the flux density of 10÷12 yrs is present. The delays in flux variations of a source at different frequencies and in different periods of the activities for successive frequency pairs from 36.8 to 14.5 GHz are changing within from 0 to 2 years.
