    Abstract: A diversity receiver includes first and second reception circuits using a superheterodyne principle. At stationary reception, reception of the audio signals and the data employing a phase diversity reception system is performed such that the signals received by the first reception antenna are supplied to the first reception circuit, the signals received by the second reception antenna are supplied to the second reception circuit, and phases of first and second intermediate-frequency signals are controlled and the first and second intermediate-frequency signals are added. At reception-frequency search, reception of the audio signals employing an antenna-switching diversity reception system is performed such that the signals received by at least one of the first and second antennas are supplied to the first reception circuit and reception of the data and the reception-frequency search are performed, and the signals received by the first and second antennas are supplied to the second reception circuit.

    Abstract: A method and apparatus for operating a radio reception system, which comprises a plurality of receivers assigned to a common output device, in which one of the receivers is designated as audio receiver and is tuned to a frequency of a radio transmitter, and outputs a signal received from the transmitter to the output device. At least one second receiver is designated as search receiver, and continuously searches its own reception frequency band for a frequency of the same transmitter. The system changes to a frequency of this transmitter, which was found by the search receiver, if the quality of the signal received by the audio receiver falls below a certain limit.

    Abstract: A method of masking interruptions in the playback of received radio signals is provided, in which lengthy interruptions are allowed only when modulation of the radio broadcast program currently being received is recognized as speech, and a modulation pause in the received radio signal is detected. This method permits essentially complete masking of lengthy interruptions in playback or making them inaudible, in which these interruptions are necessary, e.g., for analysis/testing for a transmission frequency of transmitted RDS information to be used as an alternative to a transmission frequency currently being received.
