Why does my radio sound better when I touch it?

The signal quality increases because your body is an antenna. You increase the radio antenna length and hence it’s “gain” when you touch it. This effect doesn’t happen at all frequencies and the increase in gain is fairly small. It can make a difference if the signal you are trying to listen to is weak.

How do I stop my radio from Led interference?
