CBAM-FM is a radio station broadcasting at 106.1 MHz from Moncton, New Brunswick, Canada, and is the local Radio One station of the Canadian Broadcasting Corporation. CBAM broadcasts with a power of 69,500 watts.

The Canadian Radio Broadcasting Commission owned and operated a station in Moncton under the call letters CRCA, which has previously been CNR Radio station CNRA. The station was closed down in on October 31, 1933 in anticipation of the construction of a more powerful transmitter in nearby Sackville, New Brunswick that would cover the Maritime provinces.[1][2] The CRBC was closed down in 1936 and replaced by the CBC, which inherited the project.[3]

On April 8, 1939, the station signed on as CBA, a 50,000-watt clear-channel station at 1050 AM. It was the CBC's clear-channel outlet for the Maritime provinces, heard in the daytime over much of New Brunswick, Nova Scotia and Prince Edward Island, and at night audible over much of Eastern Canada and the Northeastern United States.

As a result of the North American Regional Broadcasting Agreement treaty, it moved to 1070 AM on March 29, 1941. The original city of licence was Sackville, the location of the transmitter site. The city of licence was later changed to Moncton in 1968 when the CBA transmitter, one 460-foot tower (140 metres), moved to Dover Road in the rural community of Fox Creek near Moncton. In the 1950s and 1960s, CBA AM's studios were located on St George Street in Moncton.

In September 1970, CBA and its French-language counterparts CBAF and CBAFT were given approval to relocate their studios and offices in a new complex at 250 Archibald Street today known as Universite Avenue.

On January 8, 2007, the (CRTC) approved the station's proposed move to 106.1 FM.[4] Since Radio 2 had the local call sign of CBA-FM, the Radio One network adopted the CBAM-FM call sign. The engineers were at the AM transmitter site on Dover Road in Dieppe to say goodbye to the old AM signal that signed off for good on the morning of April 7, 2008 shortly after the 8:30 CBC news.[5][6] CBA was the last AM station in eastern New Brunswick, and the CBC wanted to stop a drop in market share.

CBAM was a former call sign of a defunct CBC low-power AM transmitter in Edmundston, which converted to FM as CBAN-FM, an FM rebroadcaster of CBZF-FM.

The original CBA transmitter site at the Tantramar Marshes near Sackville continued to broadcast Radio Canada International around the world on shortwave radio as well as relay broadcasts for several foreign shortwave broadcasters. For the purposes of CRTC licensing, the Sackville complex was designated under the call letters CKCX.[7] The shortwave site discontinued broadcasts on December 1, 2012, after which its facilities were dismantled.[8]

CBAM currently produces a local news and current-affairs morning drive time program, Information Morning. It also carries midday, afternoon and weekend morning shows produced at CBHA-FM Halifax, Nova Scotia for Atlantic Canada. Every November, CBAM-FM hosts a local radiothon for the Dr. Georges-L. Dumont Hospital Foundation, with proceeds going to the Tree of Hope Campaign. This radiothon airs only on CBAM-FM.

On October 25, 2013, the CRTC approved the CBC's application to relocate the facilities of CBAM-FM-1 Sackville to a new transmission site south of Ogden Mill; this was due to the closure of the CBC's shortwave facilities, where the local repeater was also located.[9][8]
