In NE PA, between Pottville and Hazleton :
The delightful WWSM and its traditional C&W music is all day, with a solid signal. They were even pretty good when local WMBT Shenandoah had been on the air on 1530 -- a matter of a 90 degree null. I was recently informed that WWSM was the former WAHT Lebanon. Their COL is now Annville-Cleona.
Can't get a good enough null on them middays in recent tries to get the unique WRNJ Hackettstown NJ, which appears to be pretty omni my way at that time. Perhaps some sunrise I'll be able to dig out WRNJ. Lol -- it's tough enough to find a listen-at-work station, of which WWSM is one. Why would I wanna null them?
At SSS, and even earlier during the mid-winter skywave, WWSM gets hacked apart first by Boston on 1510, then by WLAC. But they're the predominant one even at twilight time, until they sign off.

By the way, Hazleton is spelled wrong, despite it having been named after hazel trees along some crucial commerce road. Some clerk misspelled it, and it stuck.
