Hi everyone, I've always wanted to build a FM radio for myself and listen to some music, I searched the internet but some of the parts were difficult to find, I want to create a compact radio and I want parts I can find on Mouser, for both THT and as SMD components as I plan to put it on a breadboard and make some changes and then move onto a PCB, let me know if there are some good sounding FM receiver schematics that work.
Have you worked with RF circuits before?
Building RF circuits that work at 100MHz and an IF that works at 10MHz is not a trivial exercise.
It's unlike you could get a breadboard to work properly unless it is carefully laid out and built on a vector board with a ground plane.
Most present FM receivers use devices controlled by microprocessors & the RF ICs cannot be used alone.
You could just replicate the circuit from the Elenco kit radio, if you want all-discrete components? Some scrap old scrap FM radios could be a source of parts..
The circuit is on the last page of the manual, downloadable from the kit page here:

A Crutshaw says, it is very unlikely to work on a plug-in breadboard.
"Dead bug" construction on plain copper board is far better for RF prototyping.
