摘要	We analyze the radio light curve of 3C 273 at 15 GHz from 1963 to 2006 taken from the database of the literature, and find evidence of quasi-periodic activity. Using the wavelet analysis method to analyze these data, our results indicate that: (1) There is one main outburst period of P1=8.1+/-0.1 year in 3C 273. This period is in a good agreement with Ozernoi's analysis in optical bands. (2) Based on the possible periods, we expect the next burst in 2014 October.
