Pittsburgh, of course, had WZUM for half a century (WPLW at times) before a mix of problems caught up with that AM 1590 and put it off the air once and for all last year.
The station I don't get on AM 1590 is WAKR, interestingly enough. I've had two stations battle on that frequency here during the day in recent months:
(1) WGGO, Salamanca, NY, ESPN Radio, 5 kw-day, 14 w-night.
It shouldn't reach St. Mary's, PA. I could get it in McKeesport, PA.
(2) WHGT, Maugansville, MD, religious, 15 kw-day, 58 w-night. Serves Hagerstown as a local affiliate of the Fundamental Broadcasting Network out of North Carolina.
Its "figure 8" day signal isn't supposed to reach Cumberland, MD.
