The signal appears to be getting into the Pre-Selector (rf filter section) for if I disconnect the main input cable between the Pre-selector and the receiver the emission goes away. We have checked all the interconnect cables and they seem ok. It is possible it is getting in through the power cord. It hasn't been a major issue for us so we really haven't put much effort into figuring it out. There are only two people who work in that area and they can easily recognize and resolve the problem if seen.
