Rock of Boston to cease rocking on the FM dial: WBCN goes digital-only in August

CBS Radio announced today that the station now known as Mix 98.5 (WBMX) will become "98.5 The Sports Hub" on August 13. The new call letters will be WBZ-FM and will feature a mix of sports talk and play-by-play programming. The morning drive time slot will be occupied by the Toucher and Rich show from WBCN.

WBMX's current "'80s-'90s-now" Hot AC format will be moving to 104.1 on the dial with its programming and personalities intact and will be renamed Mix 104. Which means that on August 12, WBCN, "the Rock of Boston," will cease to exist on the FM airwaves after 41 years.

WBCN may be going to that big mattress in the sky, but according to the CBS press release, it will continue to exist online at www.wbcn.com. (And on 98.5 HD 2 for people with HD radio receivers). We're checking right now to see what that means in terms of music and deejays and if this means the end of the Rumble as well.

The "Sound Effects" team will have more on this in tomorrow's Globe and hopefully an update in this space later today.
