How do I turn off the ignition noise in my radio?
Carbon tracking in the ignition system is a noise source. Be sure both ends of the antenna are properly grounded and corrosion-free. There are two ways to reduce noise: by using an inductance in a power cable to keep the high-frequency noise from traveling, or by using a capacitor to shunt it off to ground harmlessly.
What is the sound of a radio?
