Some chips I have tried in the past, but I forgot which ones I don't know which module is good today
I want to add a FM radio module to a Raspberry Pi internet radio, but I have not yet decided which one. I tried with antenna amplifiers, that helps only a little. I was thinking about a pre-tuner, that works very well for the AM band but not for the FM band.
It is tricky, some 40 years old analog radios are ten times better than brand new digital ones. I tried FM radios with DSP. The audio quality is surprisingly good, but if the radio signal is weak, then the noise is very loud.
When buying something, you first have to verify that there is a good library for it.
The Chinese RDA5807M is a replacement for the Philips TEA5767. It might be a little better, but not much as far as I remember.
Silicon Labs has a whole range of good quality chips: Audio and Radio ICs - Silicon Labs. But some are already 10 years old. There are Arduino projects with the Si4735, that would be a good choice (but not good enough for me).
The Si4735 is very sensitive for a bad design of the module. I bought a Si4735 module once that lost most of the antenna signal before it reached the chip.
If you find a good module, please let me know.
