ABSTRACT:
In a receiver comprising a forward-reverse-stop search tuning circuit (43, 33, 35, 23, 19, 13) and a manual control circuit (37, 33, 35), a last-found transmission blocking circuit (45) is used which, with the aid of a control element (115), can be adjusted to a state which causes, after a restart of the search tuning circuit, tuning to the transmission found last to be effected, so that any manual tuning effected after a first search tuning action is corrected.
