I made a radio with some Velleman modul / kit. It works fine!
There are two small issues:
- Display updates produce a noise. One can hear it when music or speech is quiet.
- A station at 96.00 MHz is noisy (in stereo mode) although its signal is strong maybe arduino’s crystal 16MHz is causing this?
Schematics:
Has anybody an idea if I can improve these issues by some capacitors?
