X Some Final Comments (By Mike Gruber, ARRL Laboratory)

I hope we've succeeded in providing you with some new and better insight into the problem of power-line noise. Most sources are relatively easy to find with a little practice. While we've provided you with some general guidelines and information, experience is often the best teacher. We hope this article, coupled with the additional resources we've discussed at RFI Services and the ARRL, will help guide you along that path. We wish you the best in locating and solving your power-line noise issues!
