Once upon a time, the few opponents in Congress to the low-power FM bill then pending in Washington D.C., made up a fake compact disc and distributed it to legislators, claiming it contained the sounds of interference that low-power stations would cause over the signals of much more powerful full-power stations. Of course, giant full-power FM stations would interfere with small low-power FM stations, if radio engineering was incorrect, not the other way around.
Now that Congress has allowed two different low-power FM bills to pass, and thousands of stations to go on the air, Radio World reported that the Federal Communications Commission made their first ruling on this issue.
A Birmingham, Ala. FM station, WDJC, raised repeated concerns about interference from three planned LPFMs stations, all with religious-based programming.
Kimtron Inc., part of Crawford Broadcasting claimed their high-definition digital signals were endangered by the low-power stations, but the FCC did not buy that argument, and still, no one has proved that low-power FM stations interfere with full-power stations.
