I found the National Geographic New York City Area Map from 1964. If I can figure out how to scan it from my Epson Printer to Mac Book, or if any of you can suggest how to accomplish this, I can try to scan it and email to someone here. So far, I have found about a dozen sites on the map. They are very difficult to spot. The WBBR 1330 site is shown on Staten Island.
Let's see how well I can do this from memory:
In 1964, the NYC AM sites would have lined up thusly...
570 WMCA Kearny NJ (same site as today)
620 WVNJ Livingston NJ on NJ 10
660 WNBC just moved to High Island in the Bronx from Sands Point LI
710 WOR Carteret NJ (1935 site; they moved to Lyndhurst in 1967)
770 WABC Lodi NJ (same site as today)
830 WNYC Greenpoint, Brooklyn (now WNYC Transmitter Park)
880 WCBS just moved to High Island from Columbia Island off New Rochelle
930 WPAT Clifton NJ (same site as today)
970 WJRZ Kearny, down the road from WMCA (moved to Hackensack a few years later)
1010 WINS Lyndhurst NJ (same site as today, but the old 4-tower inline array)
1050 WHN East Rutherford NJ (next to future Giants Stadium site)
1130 WNEW Kearny, near WMCA and WJRZ (moved to Carlstadt in 1968)
1190 WLIB Astoria, Queens on a pier in the East River (moved to Lyndhurst 1967)
1280 WADO Carlstadt NJ (same site as today)
1330 WPOW (ex-WBBR) 1111 Woodrow Rd, south tip of Staten Island
1330 WEVD was by then sharing the WPOW site, but their previous site was in Maspeth, Queens
1380 WBNX was already in Carlstadt by then, down the road from WADO, I think
1430 WNJR might have been in Union NJ by then, or might have been at an earlier site
1480 WHOM was by then at the present site in Ridgefield Park NJ.... I think
1560 WQXR Maspeth, Queens
1600 WWRL had by then moved to Secaucus NJ, but I wouldn't be surprised if a map still showed them at Woodside, Queens
It's amazing how much was on the move in the 1960s - between 1963 and 1970, WNBC, WOR, WCBS, WJRZ, WNEW and WLIB all moved to new sites, at a minimum.
