An apparatus for the detection of information expected to be present in a defined data block of a RDS data flow transmitted as a predetermined number of groups which periodically follow one another, with a radio receiver tuned-in one after the other to a number of senders to be tested and whose RDS decoder is synchronized with the RDS data flow of the respective tuned-in sender. A running counter is provided having the frequency of the RDS data cycle and which is respectively reset upon reaching a count status corresponding to the period of a number of groups.
