Noise Diagnosis - Frontway Noise

Any noise which is brought into the radio system through the antenna. (Noise can be eliminated by unplugging the antenna from the back of the radio.)

Some Causes:
^ Poor grounding or missing grounds of the antenna base, the receiver, some electrical components and/or body parts.
^ Damaged or marginal components such as relays, solenoids, switches and electric motors.
^ Something near the antenna coax or corrosion at antenna coax connections.

Solutions:
^ Always verify grounding first. If more than one component interferes, a poor ground probably exists.
^ Pinpoint the source: suppress, shield or replace.
^ Reroute noisy wires if necessary.
