We're not in a rated area here in Coal Country. But for what it's worth signal-wise, only 690 puts in a good signal here, of the four Philadelpha stations shared by high-power Canadians.
If the link here from Radio-Locator goes through, you can locate us on the map. There's a straight line of country boundaries which starts at the Delaware, shaves NE Philly, and ends at Schuylkill County. Extend it from there on the same bearing. We're just west of that big beige patch which goes into both Schuylkill and Carbon counties.

For decades, AM stations in PHL and NYC (and other East Coast markets) have located their towers west or northwest of town, and sent their signals blazing through downtown and then out to sea. On an endlessly mired list irrespective of power increases, WNWR is one such facility. WFIL, WMCA, WVNJ, WPEN (at night), WIBG, WNYM, WDAS (WUBA), WWRL, et al have their strictest coverage area over the downtown of their communities of license and that's their fate.
It'd be great to hear traditional Country on 1540, or more relevant Oldies, or even Standards, or maybe even Jazz while WRTI is in their Classical mode. But each of those formats would be a wastebasket bandaid after a short while.
Oddly : If WNWR were to go some form of Asian, we wouldn't be able to get them here because of a Toronto station with similar programming on 1540.
