I don't know, but I think it may be a legacy from the days when the FRC
divided the country into regions. Note that of the stations on your list,
only WOR is a former Class IB; the rest were IAs. WOR definitely suppresses
radiation to the west (actually the northwest). The others are ND, although
WEAF, the prdecessor of WNBC/WRCA/WNBC/WFAN. used to directionali to the WEST.
A year or so ago, I read a posting on rec.radio.broadcasting from a
consulting engineer who said that the 660/670, 770/780, and 880/890 pairings
do not conform to current FCC rules on adjacent-channel skywave
interference. If that's so, then there's a worse violation in 760/770. WJR
is a couple of hundred miles closer to WABC than WBBM is.
BTW, before NARBA (3/29/41), what is now 770/780 was 760/770, and what is
now 880/890 was 860/870. But 660/670 did not change.
