The announcement briefly described what the group believes will be the problems associated with the towers. One of the things they mention (and that is usually mentioned prominently) is 'blanketing interference.' It's surely a troubling phrase, insofar as it seems to imply that the radio towers will blanket the surrounding area with interference. And, given that radio towers are all over the place, it seemed that if all those places were being blanketed with interference, we would all have had some experience with it. And yet, the people I talk to for the most part have no such experience.
So I Googled 'blanketing interference' to see what it means. Mostly the definition is more technical than I can make sense of, but it does not appear to mean that the area around the towers will be blanketed (ie, smothered) with interference. One site defines it thus: "Blanketing interference refers to the phenomena of receiving radio signals on devices not designed to do so." This site goes on to discuss how such interference can be eliminated/corrected/remedied.
A look further about the law of such intereference problems explains that the FCC requires a new station or a station that moves to a new locale to take on the costs of remedying all interference problems reported during the first year of its operation. (There are some exceptions, but they are described in the following excerpt from the applicable law.)
