FM 100 should have a much better signal than they do. I have heard 99.7 out of Jackson MS interfering around Holly Springs as well as the WWTN signal the other poster mentioned. I would bet someone a farily good amount of money that there is something wrong with the FM 100 antenna system, or else the pattern has changed considerably and for the worse since they replaced the antenna a few years back. If I was still CE there I'd be looking for a problem. It's just not like it was.
So FM 100 had better coverage "back in the day" than they do now? I was kind of disappointed in the overall coverage of the station after seeing their 290H / 96V kW power as shown in the FCC database. I figured it was low antenna height that was the culprit. Some mornings I've taken a good clear signal all the way into the bootheel of Missouri, south towards Jackson it seems to die out quicker than 102.7 or 104.5, where the 99.7 from Jackson starts makin' gravy.
And to add to the thread, antenna height is probably more important than power on FM. To wit, WDXB, licensed to Jasper, Alabama. They were atop the "Tuscaloosa tall tower" in rural Tusc. county, at about 2,215 feet HAAT. With just 73 kW, it has a massive coverage area, from near Tupelo to Ardmore, TN; Gadsden, south to Greenville, AL and then some... Relocated a while back to Red Mountain in downtown B'ham, up to 100 kW @ about 1300' HAAT, but the coverage just isn't the same since the move. (Terrain issues kept their signal from performing well in the B'ham metro, a 35+ mile hop from the TX site.)
WMC-FM seems to be solid in the city, but not so much elsewhere. Other than WVIM, I don't recall any FM's I listened to that did poorly in midtown/downtown, though...
