Abstract
A radio device includes a receiving part ( ) formed by a high-frequency selective amplifier stage ( ) including a frequency selective circuit ( ) having a plurality of capacitive elements ( ), any one or more which can be selectively connected into the selective circuit in dependence on a control magnitude stored in a storage element ( ) in order to tune the selective circuit to a certain frequency. Under the control of a microprocessor ( ) the stored control magnitude is set to that which gives the best level measured by a level detector ( ) at the output of the amplifier stage. The microprocessor varies the control magnitude to produce a series of alternate connections into the selective circuit of each and every combination of one or more of the reactive elements, receives the measurement by the level detector of the level at the output of the amplifier stage or each control magnitude, and selects the control magnitude giving the best level.
