I.B. Iquity said:"Listeners *do* use weak signals if a distant station has programming they want to hear that isn't A licensed station has a protected contour. that is a geographic area within which no other station can interfere. Outside of that area there is no promise that a station can be heard. If you have a small clock radio and I have a JRC with a beverage attached and I can receive a station from Europe and you can't what does that mean? The very weak station has no legal protection against interference. Those are the laws.
You are correct about the letter of the law.
The problem is, listeners have come to expect stations to be receivable way past their protected contours. It is simply something they have always been able to do, and taking it away will get an unfavorable reaction. Your average radio listener doesn’t know broadcast law from a dish of baked beans. All they know is they've always been able to hear a particular station in their home or car. Suddenly they may not be able to.
Contrary to views that have been expressed here, quite a few people do listen to “out of market” stations. It’s not just a bunch of crazy DX’ers. They are mainstream enough to show up in Arbitron ratings. I’ll grant you that it is more of a rural phenomenon than an urban one, but it exists. It is also fairly common in suburbs of very large cities like Dallas and Houston where rim shot stations from outside of town are receivable on your car radio all through your commute to work downtown.
It may be true that 80% of the population lives in 20% of the land mass; it hardly seems fair that those rural or suburban people must suffer so the urban dwellers gain. That’s a pretty draconian point of view. With a medium that is supposed to be fun, educational and entertaining, the only good formula for success is one where everyone wins.
