I want to learn all the basics about making a simple radio project.

The project is simple... One transmitting device (which only sends out analog signals of some decent frequency.. say 50MHz) and one receiving device which will have an LED and it will light up only when it receives the signal that is produced by the transmitter.

The project is simple.. I wish to learn everything from scratch and implement it using discrete semiconductor components (No not IC's)

I have searched most part in the internet and almost all of them just show only finalized circuit and thus there is no learning process involved.. I wish to learn the entire electronics/physics behind it as I implement it.. Any Book/link will will do...

    \$\begingroup\$ I have even implemented a crude FM radio transmitter.. But I found absolutely no content on simple receiver on the internet \$\endgroup\$

  • \$\begingroup\$ I too have seen countless schematics of FM receivers and have even made few, but so far I was unable to actually find a guide with a nice, easy to understand and thorough description of what's happening. \$\endgroup\$

    \$\begingroup\$ The books I've tried, the ARRL ones for example, go from fairly basic to complex really quickly. Good for a reference I guess but not really for the beginner. In the same boat. Did some basic EMC courses but not ehough I guess. \$\endgroup\$

Try The Electronics of Radio. It provides a filter by filter, oscillator by oscillator guide of building a radio. The end result radio might be more complicated than what you are looking for, but I found the explanations and problems to be helpful in my understanding of electronics.

This book was written by a professor specifically for a class he teaches. Disclaimer: I took that class.

  • \$\begingroup\$ I will have a look at that book as soon as possible.. Fully Fledged radio design will be perfect for me if it teaches me how all the parts(at the root level) work beforehand.. \$\endgroup\$
