REDUCING NOISE
Because your CB is exceptionally qui- et, any noise you hear through the CB is probably from an external source in your vehicle such as the alternator, an- other radio, or spark plugs.
The transceiver uses an ANL (Auto- matic Noise Limiter) circuit to reduce noise. However, if possible, try to elim- inate 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 re- duce or eliminate such noise:
•Make all CB power and antenna wires as short as possible.
•Route the power wires away from the antenna wires.
•Be sure that the chassis ground connection is secure.
•Replace old ignition wires with new,
•Install noise suppressors on your spark plugs, or install new spark plugs that have
•If problems persist, check your alternator/generator and regula- tor gauges. You can reduce the noise from these sources by using bypass capacitors at the various output voltage points.
Your local RadioShack store has a wide selection of noise suppression accessories.
