CBHA-FM
CBHA-FM is a Canadian radio station. It is the CBC Radio One affiliate in Halifax, Nova Scotia, broadcasting at 90.5 MHz on the FM dial. It is the flagship CBC Radio One station for the Maritime provinces. CBHA's studios are located on Chebucto Road in Halifax, while its transmitter is located on Washmill Lake Drive in Clayton Park.
==History==
The station was launched in 1944 on AM 1240 with the call sign CBH. Prior to its launch, CBC Radio programming aired on private affiliate CHNS 960 and its shortwave relay CHNX-SW 6130 kHz (in the 49m band). CBH's initial power was only 100 watts and remained at that level for 18 years. In 1947 the station moved to the CBC Radio Building on Sackville Street. In 1948, the frequency was changed to 1330, and then to 1340 in 1960. In 1963, the station moved to 860 AM and boosted its power to 10,000 watts.
However, CBH had to conform its nighttime signal to protect clear-channel sister station CJBC in Toronto, rendering it practically unlistenable at night in some parts of Halifax. To solve this problem, an FM rebroadcaster, CBHA-FM, was established on FM 90.5 in 1977.〔Decision CRTC 77-309〕 While it was only intended to be temporary, the CBC was unable to obtain the funding necessary to upgrade CBH's AM signal.〔(Decision CRTC 86-709 )〕 On October 1, 1989, the AM station was shut down, and CBHA-FM became the main CBC station in Halifax.
