摘要

System for the reception of modulated frequency signals and their conversion into modulated amplitude radiofrequency signals, applicable to amplitude modulation receiver apparatuses, especially the so-called auto-radios, characterized in that a converter-modulator set comprising an electrically shielded cover, a frequency modulated tuner, an amplifier and detector, an oscillator and modulator, and an input switch, mounted in such a way that through two external connections of said switch, interposed in the connection cable of the own antenna of an amplitude modulation receiver apparatus, said converter-modulator set, depending on the position of the switch, can be connected in series with the amplitude modulation receiver apparatus and this receives the frequency modulated signal converted into a radio signal. amplitude modulation frequency or, alternatively, act independently of dich or converter-modulator as normal receiver amplitude modulation device.
