Entercom Communications Corp. and CBS Corp. are looking to unload a handful of big-name Boston radio stations as part of an ongoing merger.

Entercom refused to confirm what radio stations they would be divesting as part of the merger process, and CBS Radio through a statement declined to comment on Tuesday.

But someone with knowledge of the merger confirmed that CBS Radio is looking divest radio news giant 1030 WBZ, 98.5 The Sports Hub, and classic rock staple 100.7 WZLX, while Entercom is proposing to divest talk radio mainstay 680 WRKO and the R&B station 97.7 WKAF.
