Volume and noise #8

Open codeput opened 3 years ago

codeput commented 3 years ago

I realized that the volume, even if set to zero, does not go down completely and in MW the noise is very high and covers weak signals.

Noise is probably coming from the powersupply. Never use a switchmode psu. Check out with a battery or a real analoge psu. If you want to change the volume at the lowest level, check Line 1138 in my sketch. In vol=map(vol,20,63 etc you can change 20 tot 0 and the radio is really quite. I use the mute for that.
