Abstract

For tuning a microcomputer-controlled radio receiver to the one of several transmitters broadcasting the same program best satisfying the requirements for quality of reception the information obtained from the RDS data stream is memorized in a table of the alternative transmitters and sorted in the priority of the corresponding quality of reception. In establishing the priority in the table of alternative transmitters not only quality evaluation information but also a current status information depending on the time and/or distance covered is determined and evaluated. Particularly for mobile radio receivers having only a single receiver section this method alleviates the circumstances that obtaining the information determining the priority for all alternative frequencies contained in the RDS data stream is considerably time-consuming and that the information held in the table may reflect the conditions at any one time incompletely or incorrectly.
