Question by electrical2601: Where are some good resources in building an FM radio from scratch?
I want to learn FM radio reciever theory well enough where I can build my own FM radio from scratch without using someone elses skematic. I know it will probably be hard but I know it’s possible if I can be guided to the right resources.

Try to find a seasoned ham who can explain the basics of RF to you. This stuff is not so much hard as it is tricky. It is also 10000% easier if you have the right tools and measurement instruments. To build a radio if you have both a spectrum and impedance analyzer is a walk in the park and extremely instructive. You will learn in no time and be an aspiring RF pro by the time you are done. But the same task without that equipment is a nightmare. Personally (I happen to be a professional), I wouldn’t go near any RF circuits without the right lab equipment. But maybe that just shows my age and limited willingness to frustrate myself when I know better.

Good luck and have fun!
