Has anyone else noticed severe interference to the entire AM band in the Lowell/Tewksbury/Andover area? I have table radios in 3 different parts of my house, and the entire AM band is a loud HUMMMMM on all 3 of them. On a CC Radio 2 portable, the HUMMMM exists throughout the house, no matter what direction I orient the antenna. I can barely get WBZ and WCAP over the hum, but the rest of the AM band is a washout. I no longer have a radio in my car, so I can't tell how widespread the interference is. This has been going on for about 10 days now.
