An RDS receiver having dual tuners (10,12) and dual antennas operates in two distinct modes, a diversity mode and a non-diversity mode. Diversity mode is when both tuners (10,12) are tuned to a signal with the same program audio content and the audio from both tuners (10,12) is blended together in a manner to minimise the effects of multipath distortion. In non-diversity mode, a forcing circuit (23) isolates the tuner output signals so that one tuner provides the audio output while the other can be retuned to any other frequency for purposes of gathering RDS data. <IMAGE> |
