Abstract

For the selection of a required reception signal the tuning oscillator 9 is disconnected and instead a reception signal simulating oscillator 15 is connected to the aerial input which alternately is changed over to at least two frequencies lying in the reception channel. An HF signal demodulating device 16 generates a criterion for a microprocessor 13 for indicating the optimal tuning. The resulting tuning voltage is taken in each individual case in turn to the HF circuits 3-5 intended for balancing, through a D/A converter 18-20 until an equalization of all the circuits is achieved. <IMAGE>
