The station's programming as "Caliente" was a mix of locally produced shows from 7 a.m. to 5 p.m. weekdays followed by syndicated shows from Bustos Broadcasting. It was announced in early December 2008 that WNAK, along with sister station WCDL, would be returning to a standards format. Newspaper ads have used the slogan "The Greatest Music of All Time" and have featured photos of singers such as Frank Sinatra, Tony Bennett, Dean Martin and Peggy Lee. The station changed its call sign to WZMF on April 23, 2010. WZMF switched to a simulcast of the-then 1460 kHz WGMF on May 5, 2010, airing a classic hits/oldies format. On July 4, 2018, WZMF and WGMF swapped call signs. In February 2023 WGMF rebranded as "Gem 99 & 100".
