Some months I posted a problem with a computer causing noise on an radio,I was stumped in my efforts and many fellow members did give good advice which did reduce the noise but not get rid of it totally,the customer recently requested a larger monitor,I got one of the newer LED types,installed it and the radio interference noise is nearly gone,it was the old monitor itself, a flat screen also but a much earlier design.I would have never figured it out if the farmer's wife was not engrossed with twitter and face book and wanted a bigger screen.
