Difficulty breadboarding an FM circuit


I have made a breadboard project in my college, simply to generate an FM wave in CRO. But every time I failed to generate it. I don’t what happened. Can somebody tell me where do I learn all this.

Just seeing if I understand first…

As I read it, you’ve created a circuit on a breadboard to generate a wave that you hope to view on a CRO. I’m basing my questions on that.

  • Are you getting nothing on the CRO, a bunch of random seeming noise, something else entirely?
  • Is the waveform actually supposed to be modulated (FM?) at this point, or are you just generating the carrier for now?
