This is the work of Michelle Bradley, the proprietor of REC Networks – arguably one of the most gifted FCC broadcast data-analysts in the country. REC’s been engaged with LPFM since its inception 15 years ago, and has tendered a petition for rulemaking to create an upgraded LP-250 station-class.
The premise is simple: 100 watts maximum power at just 100 feet above the ground doesn’t make for much of an FM signal. Many LPFM stations are difficult to receive indoors. REC starts off the petition with a litany of LPFM reception horror-stories (my favorite being the retirement facility in North Carolina where the local LPFM station can be heard on one side of the campus, but not the other). These vividly illustrate how LPFM’s current power/height restrictions work against stations being able to build viable and sustainable listenership and fiscal sponsorship.
