I'm guessing WXMC in Parsippany. They own the land (in a floodplain) and put a signal over a populated area, hence the asking price. I don't think the one in Mt. Kisco is worth that much. Actually, I don't think WXMC is either, but that seems to be what they're asking.
That's definitely another possibility; Morris County is in the NY MSA. Both Mt Kisco and Parsippany only have about 100 thousand people in the 5 mv/m contour, making $1.9 million seem high. But Mt Kisco sold for over a million 10 years ago, while Parsippany got only $200 k about 19 years ago. WLIM went for $850 k about 9 years ago.
