Reducing Noise
Because the CB itself is fairly quiet, most noise you hear is probably from an external source in your vehicle such as the alternator, another CB, or spark plugs.
The transceiver uses an ANL (Automatic Noise Limiter) circuit to reduce noise. However, if possible, try to eliminate the noise by finding its source.
You can determine the noise’s source by turning off the engine and operating the CB with your vehicle’s ignition set to ACC. If the noise is reduced, the problem is in your vehicle’s ignition or electrical system. Here are a few hints to help you reduce or eliminate such noise.
