A receiver, adapted to the reception of identification data in accordance with the RADIO DATA system (RDS) and having only one tuner, effects the acquisition of the identification code of an alternative channel by sampling the alternative channel during periods in which the audio output of the receiver is muted. These periods are of such a short duration that they are not noticed by the listener.
