K-Love is a giant Contemporary Christian radio network heard in 45 states on over 440 stations and translators. This 1998 sticker could easily be from more than one of their affiliates. In fact, a quick Google search found a K-Love station at 90.7 in Dyersburg, Tennessee (WZKV) and a translator at 90.7 in Golden Valley, Minnesota (K214DF.) Chances are we'll never know exactly which station this sticker is from.
While filing away the 90.7 decal I found another K-Love mystery sticker for 104.7 FM.
