A radio broadcasting receiver having an auto tuning means (B2) and a digital signal processor (B3) is disclosed, in which the digital signal processor includes a detection means for detecting a maximum value of a received signal output for each of a plurality of broadcasting stations selected during station selection, a storage means for storing a detected maximum value of received signal output of each of the broadcasting stations, a computation means (D3) for calculating a mean value of a plurality of stored maximum values of received signal outputs, and a means for calculating an output gain on the basis of a maximum value of a received signal output of a broadcasting station to be received and the mean value, and there is provided a means (B4) for conducting a gain control upon station selection according to an output of the digital signal processor (B3)so as to instantaneously bring the received signal output closer to the mean value, and which conducts automatically a sound volume adjustment at the time of station selection. <IMAGE> |
