I know earlier in radio many stations shared frequncies,but in the late 50's / early 60's I recall 2 of the last to do so in the NYC area.. 1330 WEVD and 1330 WPOW. Also 1380 WBNX and 1380 WAWZ ( Zarephath,NJ ). If I recall correctly 1380 WAMS in Wilmington,DE was affected by WAWZ and had to alter their DA pattern when WAWZ went on the air.
1330 had separate transmitter sites in the NYC area ,1380 did too , mainly because Zarephath is down near New Brunswick,NJ, not real close to NYC.
I don't recall when these shared agreements ended ,since I left the area in the 70's.
WAWZ-AM was owned by Pillar Of Fire International, the FM ( WAWZ-FM 99.1 ) they have today is still owned by the group.
