The 92.7 site is atop North Shore Towers, just east of the Queens-Nassau County Line, adjacent to the Long Island Expressway. It pumps out 2 KWs from a HAAT of 522 feet. There's a large population of residents in those towers, plus thousands of others within walking distance, many of whom are retired or outright elderly. Shooting more RF power from that location, especially on 1560 Khz (if I'm understanding your comment correctly), would never pass muster there. They'd be in a battle with locals for decades, well beyond the date when what remains of AM service is taken behind the barn, so to speak. As is, those 2000 watts cover a good chunk of the five boroughs, all of Nassau, and parts of Westchester, Suffolk and the close-in New Jersey coast with their 60 dbu, and a bigger subset of the metropolitan area to their 50 dbu contour. If that's not enough coverage for them, maybe their war chest would be better spent by acquiring suburban FMs in northern New Jersey and/or upper Westchester, instead of tilting at high-band AM windmills.
