As shown in the figure is an intermediate frequency signal generator made of ceramic filter3L465.It is simple to handle and it will be esay to start oscillation.And the intermediate frequency signal produced by it is stable and have sound repeatability.It can output audio signal as well.Operating principle: VTl, VT2 and other related components constitute multivibrator with a frequency of about 400Hz.It can be used to regulate intermediate frequency signals and the audio signal can be output from point A. VT3, VT4 compose intermediate frequency signal generator, in which DL will select the frequency. Adjusting RP could change the oscillation intensity.Connecting a wire of dozens of cm long at point B can output the the modulated intermediate frequency signal.As for the multivibrator,as long as all the components are connected in the right way. oscillation will start as soon as swtiching on.
