That requires WKMB to sign-off at sunset to avoid interfering with this station and Class B WFNI in Indianapolis.

WKMB signed on in February 1972 with an adult contemporary format under the ownership of Herb Michaels.

It changed to a country music format in 1979; in 2002, WKMB became the only commercial radio station in the New York City area to broadcast country music after a four-station simulcast on 107.1 FM dropped the format for Spanish-language programming.

King's Temple Ministries had earlier bought time on WERA before that station shut down in 1997.
