We search for indications of waves in the 25 - 2000 MHz radio spectrum of the 1 August 2010 event , where fast propagating waves in the solar corona with periods of 181, 69, and 40 seconds were detected in UV observations. Using the wavelet technique, we construct a new type of oscillation map for selected periods in the whole domain of the radio spectrum. While an oscillation with a period of 181 seconds was recognized in the whole 25 - 2000 MHz radio spectrum, oscillations with periods of 69 and 40 seconds were only confirmed in the 250 - 870 MHz frequency range.
