CKKL-FM is a Canadian radio station, which airs at 93.9 on the FM dial in Ottawa. The station uses the on-air brand name Bob FM.
Frank Ryan originally launched the station in 1947 as CFRA-FM, simulcasting the programming of its AM sister station. In 1959, the station began airing some separate programming. In 1961 Ryan sought approval to increase power from 860 Watts to 146,000 Watts via a new transmission site at Camp Fortune.  The site Ryan Tower would become the area's main radio and television transmission site. Two years later, in 1961, the station's programming became fully independent of CFRA's, and the station adopted the callsign CFMO. CFRA and CFMO were subsequently acquired by CHUM Limited in 1968.
The station's morning show, Cub & Company is hosted by Cub Carson and Melanie Adams and until February 2013, Sandy Sharkey. The show was formerly hosted by "Stuntman" Stu Schwartz, who is now at CJMJ-FM.
In 2007, CTVglobemedia bought CKKL-FM along with the other CHUM Limited properties. As of 2011, Bell Canada acquired CTVglobemedia, renaming the company as Bell Media.
On February 1, 2013, Bell Media announced that longtime BOB-FM announcers Steve Gregory and Sandy Sharkey were leaving the station during Bell's yearly cuts.
