Method for suppressing undesired automatic transmitter change-over

1. A method for avoiding unwanted, automatic station changes in mobile radio receivers.2.1. For mobile radio receivers that can receive RDS data, when reception quality drops below a certain limit, all alternative frequencies are first checked for their reception quality, and if no receivable alternative frequency is found, a search is started. For disturbances that affect the entire frequency band, as is the case for example in a tunnel or an underground car park, such a station search is usually undesirable and should be suppressed as much as possible.2.2. The unwanted station search is suppressed by a fast, unnoticeable search is started before the station scan, in which it is determined whether the entire frequency band is disturbed. If this is the case, the last undisturbed received frequency is set and the station search is suppressed. The fast search is repeated after a predefinable time until stations are receivable again.2.3. Mobile radio receivers suitable for receiving RDS data.
