AM/FM Arduino Radio with Philips TEA5757 modules

I once tested some radio modules for a project and made this video to record their performance. The Philips TEA5757 IC is a bit old and hard to use as it requires lots of external components, but modules based on that IC are easy to find and work very well. They are from a time when people do used to listen to AM and FM analog radio, so they have a very good performance. Both modules shown in this video work very well. The one from the MRD100 receiver has slightly lower sensitivity, but is a bit more selective. The main difference between them is the search feature: I found it to work better on the MRD100 module, but my ECO6 may require a little calibration. In this video I&using the Arduino TEA5757 library and the respective example sketch from:
