ABSTRACT:
In a tuning circuit for a receiver which is continuously tunable over a number of wave ranges by means of a setting circuit, the receiver having an automatic wave range change-over, the tuning voltage is obtained from a subtracting circuit in which a changeable constant voltage is subtracted from a setting voltage which was obtained by means of the setting circuit, this changeable constant voltage depending on the wave range for adaptation of the wave range limits to the wave range.
