Introduction
As our lives become filled with technology, the likelihood of electronic interference increases. Every lamp dimmer, garage door opener or other new technical “toy” contributes to the electrical noise around us. Many of these devices also “listen” to that growing noise and may react unpredictably to their electronic neighbors, including Amateur Radio transmitters.
Sooner or later, nearly every active Amateur Radio operator will have a problem with interference. This could involve interference to a neighbor's equipment, or, more likely, some form of intererence to Amateur Radio from the noisy devices that can sometimes even be found in our own homes. The good news is that most cases of interference can be cured! The proper use of “diplomacy” skills to communicate with a neighbor and standard technical cures will usually solve the problem.
These Web pages provide an overview and information to help find and fix RFI/EMI problems. The ARRL Lab staff recommend that hams with RFI problems purchase a copy of the ARRL RFI Book. This book, written by a number of experts, picks up where this web site leaves off, providing detailed information on the causes and cures for nearly every type of interference problem.
