The Regulatory Situation With Respect to Automobile Ignition Interference

Abstract

Ignition interference has been a trou­ blesome problem from the very early days of broadcasting. Having solved the problem of interference to AM reception in the automo­ bile, the automobile industry faced a more serious challenge with the advent of tele­ vision broadcasting. This was largely solved by voluntary compliance with SAE Standard J551. Today, the automobile industry is fac­ ing even a greater challenge: The control of interference to land mobile communication.
