We represent the radio observational data of Active Region oscillations made with the help of radiotelescope RATAN-600. The observations of a number of AR\'s during period from March 14 to March 22, 2002 were carried out in new regime of azimuth observations covering 4,5 hours with 4 min cadence simultaneously at several wavelengths at microwaves. The different temporal behaviors of some ARs and their components are detected. The wavelet analysis of radio oscillations have shown the presence of two steady periods of oscillations around 20 min and 50 min. A possible interpretation of the phenomena are discussed.
