1) The antennas connected to the Ethernet device -- their length, and their proximity to YOUR antennas (but NOT to your radio) ---------------------------------------- My router for a while sat a on a shelf just about 20 inches from my link-coupled tuner. This is an "open" tuner design using a large 3" dia by 10" long open coil with a big transmitting-type variable cap across it (you can see a picture of it on www.QRZ.com; just look up AC7AC. The router was on a shelf under the desk about where my knees are in the picture). Sure, this is a balanced antenna system and the idea is to prevent pickup and radiation from the balanced feed and tuner, but the balance is never perfect. As the photo shows, the feeders drop down near the table top (and the wireless router just below) where they pass through a header to the outside. As I wrote before, digital stuff generates noise; I'd be the last person to deny that. It's sometimes very hard to do anything effective about it. Still, the situation varies so much from installation to installation that only the most general "rules of thumb" might suggest what an particular installation will produce. That is what I was trying to convey by relating my particular experience.
