A dream of all electronics hobysts. After several failed attempts of making a FM radio, I was about to giveup the topic. All those were transistor based. None of them worked, at lest the white noise is not received. So this time, jumped to this 'radio on a chip' to get some motivation energy.
Schematic
Mostly based on the test circuit of the
Data Sheet and
this and
this.

I did not have any trimmer caps at that moment, so channels are tuned by pushing the inductor.
The amplifier is not a good one if you care the gain, health of the speaker and the power consumption. If you build this, google for a good amplifier circuit. Following circuit that was built with the parts in hand is for testing purposes only.
