From the southwest suburbs of Chicago ...
Our local 87.75 "FM" is the analog audio service of WRME-LD, the only ATSC 3.0 station in town so far. Engineers figured out how to carve out just enough room for the analog audio without the digital disturbing it, and vice versa, and convinced the FCC to allow it. The video is Jewelry TV, a home-shopping service. The audio identifies as "Me-FM" running oldies, with Weigel running it under an LMA. (The WWME calls are used not here, but on a low-power TV station.) As others have noted, it gets out quite far for a low-power signal from high atop the John Hancock Center. Next time I run out of town, I'll see how far it goes before fadeout.
WRME-LD had a pile of previous call signs in the analog lower-power days, including WLFM-LP, WKQX-LP, WIQI-LP and WGWG-LP, when WGN Radio programmed it as an all-sports station, which was a ratings dud.
In the analog TV days, Chicago was surrounded by channel 6 stations in Milwaukee (WITI), Davenport (WOC/KWQC) and Indianapolis (WRTV). My car radio could pick up WRTV well north of Lafayette (about 60 miles out) before Milwaukee and occasionally Davenport would interfere. The latter was more intrusive given it is an NBC affiliate while Indy and Milwaukee are both ABC.
