I have a friend that hears birdies on 160 M from various DishTV and DirecTV systems. He claims his own system has one at 1823 or so that drifts around. It stops when he unplugs the AC but no when he

This goes to show you it is usually not OUR problem. My old DirecTV receiver needed tons of ferrite to get the RF out of it. Tech installed a new DVR receiver with dual coax, bare bones, no ferrite.
