On January 2, 2002, WDLW was sold to WOBL Radio, Inc.'s owners, Doug and Lorie Wilber (which also resulted in a call letter bacronym). Technical upgrades were made to the air signal, and WDLW's studios were moved from the Antlers Hotel to WOBL's studio/transmitter facility in Oberlin, but the station kept the Hispanic format. But by that November 8, citing a lack of advertising revenue in order to keep the Hispanic format on a full-time basis, WDLW switched to a 1950s/1960s rock-and-roll oldies format as "Kool Kat Oldies 1380-AM." "Kool Kat" was a play on "Cool Cat," the name of a 1960s Warner Bros. cartoon character, and a popular catch-phrase in that same period. The very first song played after the format switch was The Tremeloes' "Here Comes My Baby."
