REDUCING NOISE
Because your CB is exceptionally quiet, any noise you hear is probably from an external source in your vehi- cle — the ignition, another radio, spark plugs, and so forth.
You can determine the source of the noise by turning off the engine and operating the CB with the ignition set to ACC. If most or all of the noise goes away, the problem is in your ve- hicle’s ignition or electrical system. Here are a few hints to help you re- duce or eliminate such noise:
•Do not route the power cord next to the antenna wire.
•Be sure the antenna’s magnetic base is securely attached to a metallic surface. If you use an antenna other than the magnet- mount type, be sure that the ve- hicle battery’s ground connec- tion is secure.
•Try replacing old ignition wires with new,
•Install noise suppressors on your spark plugs or install spark plugs that have
•If problems persist, check your alternator/generator and regula- tor gauges. Noise from these sources can be reduced or elimi- nated using bypass capacitors at the various voltage points.
Note: Your local RadioShack store has a wide selection of noise- suppression equipment.
