Case 8.Noise On FM
Since radios are designed to pick up signals sometimes undesired noise may be received, including:1. Multi-Path Distortion Noise
2. Weak Signal Noise (Deterioration of Signal to Noise Ratio)
3. Adjacent Channel Interference
4. Inter Modulation Interference
Therefore, if you have any doubt concerning your radio performance please compare it with other radios. Then judge whether the radio needs service or not.
