CBU (690AM) is a Canadiannon-commercialradio station licensed toVancouver,British Columbia. It carries the programming of theCBC Radio One network. 690 AM is aclear channel frequency; the station is additionally relayed over VancouverrebroadcasterCBU-2-FM (88.5FM); CBU's newscasts and local shows are also heard on a chain of CBC stations around theLower Mainland.

CBU's studios and offices are in theCBC Regional Broadcast Centre at 700 Hamilton Street inDowntown Vancouver. The AM transmitter is in theSteveston section ofRichmond and the FM transmitter is onMount Seymour.[1][2]

History

[edit]

CNRV, CRCV, CBR

[edit]

The station was launched in 1925. The original call sign was CNRV, using the slogan "The Voice of the Pacific." It broadcast on 1100 AM and was owned by theCanadian National Railway radio network.[3] CNRV was acquired by theCanadian Radio Broadcasting Commission in 1933, becoming CRCV. In 1936, the CBC was created, taking over the CRBC's operations, and CRCV became CBR.

The transmitter was located on No. 4 Road in Richmond. This site was in use from 1938 to 1976.[4]

The station moved to 1130 in 1941 after the enactment of theNorth American Regional Broadcasting Agreement (NARBA). In 1947, an FMsimulcast was launched on105.7 MHz. Distinct programming on the FM station was aired for the first time in 1964 when it joined the "CBC FM Network."

CBU

[edit]

The frequency was moved to 690 AM in 1952 when the call sign was changed to its current CBU. In 1967, a new transmitter was erected inSteveston, on the shoreline along theStrait of Georgia. The station began broadcasting at 50,000watts, the highest power authorized by theCanadian Radio-television and Telecommunications Commission (CRTC), allowing it to be heard throughout theMetro Vancouver Regional District and around theBritish Columbia Coast.

Among Radio One stations on the AM dial around Canada, CBU covers the largest area of population, since Montreal and Toronto are served by FM stations. CBMMontreal moved toCBME-FM in 1998, and CBLToronto moved toCBLA-FM in 1999.

FM simulcast

[edit]

In early 2008, the CRTC approved CBU's application for a new simulcast of its programming on the FM band.[5] On October 10, 2008, CBU began testing its FM simulcast on 88.1 FM as CBU-2-FM with aneffective radiated power of 19,500 watts, and it officially signed on soon after. Around the same time, the CBC also applied to broadcast on separate transmitters into Nanaimo, as well as the Sunshine Coast, with the intent to shut down the AM transmitter on 690 kHz if approved. The CRTC denied these other two transmitters due to the lack of available frequencies in the region.

In 2011, the CBC applied to the CRTC to increase the coverage area of CBU-2-FM's transmitter. The CBC proposed increasing the height of the antenna and raising the ERP to 36,900 watts (97,600 watts maximum). The ability to increase the signal coverage area was made possible whenCHEK-DT inVictoria moved from VHF TV channel 6 to 49, as part of the over-the-air digital television transition. (TV channel 6 is heard on the FM band at 87.75, which puts it close on the dial to 88.1, the frequency for CBU-2-FM.) This CBC transmitter application was approved September 13, 2012.[6]

Fire damages AM transmitter

[edit]

In November 2018, CBU reduced its AM transmitter power from 50,000 to 25,000 watts. A fire at the Steveston transmitting facilities destroyed part of the station’s equipment in 2017. It was decided repairs to restore the full 50,000 watts would have been too costly.

HD Radio

[edit]

CBU-2-FM transmits usingHD Radio technology on 88.1 MHz. As of April 2022[update], this signal provides simulcasts of CBU-FM ondigital subchannel HD2 andCBCV-FM on subchannel HD3.[7]

Shortwave relay

[edit]

In 1941, CBR established ashortwave relay for remote areas of British Columbia using the call sign CBRX and operating on a frequency of 6.16 MHz (in the 49m band) with a power of 150 watts. The call sign changed to CBUX in 1952 when the AM station became CBU.[8]

In 1965, the call sign changed to CKZU, recognizing that theITU prefix CB was not assigned to Canada, but to Chile. The station was given permission to increase its power to 1,000 watts in 1986. The transmitter was adjacent to CBU's AM transmitter.[8] The 2017 fire that destroyed part of the AM transmitter also damaged the shortwave broadcasting equipment.

In February 2017, the CBC announced that CKZU was unlikely to return to shortwave. The CBC stated that the transmitter was in a state of disrepair with no replacement parts available due to aging equipment. Purchasing a new transmitter would be too costly due to the minimal number of listeners who tune into the facility.[9][10]

Local programming

[edit]

CBU'slocal programs areThe Early Edition, hosted by Stephen Quinn, in the morning; andOn the Coast, hosted byGloria Macarenko, in the afternoon.

CBU also originates the lunch-hour showBC Today, hosted by Michelle Eliot and simulcast overCBUT-DT,[11] as well as the weekend programsNorth By Northwest, hosted by Margaret Gallagher, in the morning; andHot Air on Saturday afternoons. These shows (except forThe Early Edition andOn the Coast) are broadcast province-wide to Radio One's stations inVictoria,Kelowna,Kamloops,Prince Rupert andPrince George, as well as their respectiverebroadcasters.
