In a receiver having a search tuning circuit with which a group of data (39 or 41) which corresponds to certain transmitters can be searched by means of a group selection switch (43, 45) a field strength behaviour-depending starting delay circuit (61) is used to delay the start of a search action relative to both decreases in field strength and the frequency of the decreases to prevent a too frequent start of a search action (FIG. 1). |
