Tower Ticker | Eddie and Jobo are back with CBS Radio in Chicago, and Jack’s been jilted. If it’s not quite like old times at WJMK-FM 104.3, it will be closer than it has been.

Beginning at 1:04 p.m. Monday, the one-time oldies station will switch from the Jack FM variety format it’s embraced for almost six years to a mix of hits from the 1960s, ’70s and ’80s. Gone will be the disembodied recorded voice of Jack (Howard Cogan), replaced by actual live and local on-air personalities.

Rebranded as K-Hits, though the call letters won’t change, WJMK will also bring the long-time team of Ed Volkman and Joe “Jobo” Bohannon (nee Colborn) back not only to morning radio as 5:30 a.m. to 10 a.m. weekday hosts but also to CBS Radio, which cut them loose from WBBM-FM 96.3 in late 2008 with many months left on their multimillion-dollar contracts.
