From 1987 to 1990, WKLV-FM was "Jazz 96.7" and had the appropriate call letters WJAZ. In 1990, the format was changed to an oldies format of songs from 1954 to 1973 and was known as WQQQ, marketed as "Q-96.7". From 1992 to 2006, WKLV-FM was known as WKHL, marketed as "Kool 96.7", with no change in format; the WKHL call letters are coincidentally on a K-LOVE affiliate in Lafayette, Indiana. On March 29, 2006, the station changed from oldies to classic hits as 96.7 The Coast under the WCTZ calls. The FCC approved an allocations shift to Port Chester, New York in December 2006 which allowed the station greater access to New York City (though ironically, the station still marketed itself strictly to a Fairfield County audience (i.e. traffic reports never made mention of Westchester County or New York City highways, local news updates only pertained to Connecticut, etc.)).
On November 5, 2010, Educational Media Foundation announced that they will be purchasing WCTZ and moving the transmitter to the Trump Plaza in New Rochelle, New York, serving as the K-LOVE affiliate for New York City with the call letters WKLV-FM.
The last song on WCTZ was "Good Night" by The Beatles before going silent at midnight on May 19, 2011 in preparation for its move to New Rochelle, New York for its K-LOVE affiliation. The station returned to the air from New Rochelle, New York on May 30, 2011 as a K-LOVE affiliate under the WKLV-FM calls (the WKLV calls are currently in use on an AM radio station in Blackstone, Virginia).
