Chart 12 Radio Noise Entering Through Radio (Sideways Noise):

IMPORTANT: Only perform this chart if sent here from Chart 17, Radio Noise.

SIDEWAYS NOISE
Any noise that enters the audio component by a radiated field through the component case. (Noise is reduced or eliminated when slowly removing the audio component from its fastened location.)

Some Causes
Noisy wires or hoses behind or on top of the radio or antenna coax lead-in.

Solutions
^ Suppress or shield the noisy wire or hose, or reroute it.
^ Shield the radio case.
^ Use aluminum or nickel tape and ground the tape whenever shielding. (Nickel tape will also stop magnetic interference, aluminum tape will not.)
