Steve, the only time you would have heard them in NE PA was if for some reason they needed to run 10,000 watts non-directional which they had to do every once in a while for maintenance, repair, calibration, and testing. Otherwise as you said the signal was severely limited to the south and west to protect the contour of 1160 WOBM at the NJ shore. WVNJ did put a great signal as you pointed out into Westchester, Fairfield County, CT, and the northern half of Long Island all the way out through Nassau and Suffolk counties. The problem was without being able to cover all 5 boroughs of NYC it made it a very tough sell. The signal was good in the Bronx, some parts of northern Queens, and could be heard in northern Manhattan as well as the west side of Manhattan but you could not pick it up in mid-town, the east side, lower Manhattan, any of Brooklyn, or any of Staten Island.
Had the station committed to super-serving their home base in Bergen County which had a population above 900,000 they probably would have been better off. But instead they wanted to compete as an NYC station and they were completely handicapped by their signal coverage. And don't forget, they pretty much disappeared at night as they were only authorized to operate at 2,500 watts.
