Abstract

Receiver with frequency synthesis and two receiver systems (3a, 3b), of which one (3a) modifies its heterodyne frequency within a frequency band in which the reception frequency of the other receiver system (3b) lies and selects a desired transmitting station via a phase-locked loop circuit (8) and a control circuit (16). The control circuit (16) controls the tuning of the first-mentioned receiver system (3a) in such a way that the latter modifies its heterodyne frequency while avoiding a frequency range including and in the vicinity of the reception frequency of the last-named receiver system (3b). <IMAGE>
