In most cases, I believe that it's safe to say the FCC signal contours are the minimum range for coverage, since the 1mV, and even the .5mV, contours are really strong FM signals. I've always wanted to see a .1mV contour, since that's still a pretty strong FM signal. 30uV is about where many receivers can switch-over from MONO to FM Stereo. Here??? None of the LPFM's are as close as 3.5 miles away, nor are any of them Line-Of-Sight. (Then again, where I live, no stations of any kind are Line-Of-Sight to me.) The closest to me maybe WWSA-LP in St. Albans, WV.

The signal is very reliable, without any preamp, to what I use as a link FM Tuner, a McIntosh MR7084, from 1995. Out nine signal strength bars-light, it's a constant five. Heck... Back in the early 1990's, I would surprise the heck out of the college DJ's of leftover Class "D" station WECW, at Elmira College.

What did I have going for me there for that reception? They were in the valley that I was. If, I was around a hill from them, then reception would have never been possible. Up there around Cleveland, OH, the terrain is fairly flat, or somewhat non-steep inclines. FM VHF FREQ's can still refract around that, for a ways. So, the fact that you are getting an LPFM, at 95W ERP, from like 10 miles away, is no surprise at all.
