CBN is a clear-channel radio station broadcasting at 640 kHz (AM) from St. John's, Newfoundland and Labrador, Canada, and is the local Radio One station of the Canadian Broadcasting Corporation. CBN broadcasts with 10,000 watts, unlike most other clear-channel, Class A stations, which broadcast with 50,000 watts. Per international agreement (NARBA), CBN is grandfathered at 10 kW and Class A, whereas the dominant station on this frequency throughout the Americas is KFI Los Angeles, which operates with 50 kW and Class A.
CBN also broadcasts at 88.5 FM in the St. John's area.
The station began broadcasting at 8 p.m. on November 14, 1932 as VONF (Voice Of NewFoundland), broadcasting at 1195 kHz, and was owned and operated by the Dominion Broadcasting Company, a subsidiary of the Avalon Telephone Company (a predecessor of Bell Aliant). In 1934, it merged with a former competitor, VOGY 840, which had also launched in 1932. The VONF call sign was retained.
On March 13, 1939, the Dominion Broadcasting Company was absorbed by the Broadcasting Corporation of Newfoundland, the pre-Confederation public broadcaster, as its first radio station. The frequency was eventually changed to its current 640 AM.
CBN is currently the largest Radio One station in eastern Canada that is still located on the AM band, along with CBY in Corner Brook, which also operates at 10,000 watts and has clear channel designation. CBN's daytime signal covers much of the Avalon Peninsula, at night, it reaches much of the eastern half of North America.
Until April 27, 2007, CBN's operations were located on 342 Duckworth Street. Those operations are currently located on 95 University Avenue, where the television operations are also based.
The station's local shows include The St. John's Morning Show with Krissy Holmes Cross Talk with Ramona Dearing, On The Go with Ted Blades, The Fisheries Broadcast with Jane Adey, and Weekend AM with Heather Barrett.
For all intents and purposes, the province's other five Radio One stations (CBG Gander, CBT Grand Falls-Windsor, CBY Corner Brook, CFGB-FM Happy Valley-Goose Bay and CBDQ-FM Labrador City) are semi-satellites of CBN, simulcasting most of CBN's local programming (other than the morning show on weekdays) during Radio One's local programming blocks.
By 1940, VONF operated a shortwave relay for remote areas of Newfoundland using the call sign VONG and operating on a frequency of 9.47 MHz (later 9.48, both in the 31-meter band). A second frequency of 5.98 MHz (later 5.97, both in the 49-meter band) was launched using the call sign VONH. Eventually, VONG left the air and only VONH remained. The call sign changed to CBNX in 1949 when the AM station became CBN. The frequency was changed to 6.16 MHz in 1963. In 1965, the call sign was changed to CKZN, recognizing that technically, the CB call sign prefix was assigned to Chile on an international basis.
In 1989, the shortwave relay began to rebroadcast CFGB-FM in Happy Valley-Goose Bay, part-time as well as CBN. Eventually, in 1994, the station no longer relayed CBN, and became a full-time rebroadcaster of CFGB-FM. Most of Newfoundland had reliable AM or FM reception by that time, so the relay's main use was now limited to the remote areas of Labrador.
CBN has the following rebroadcasters:

CIBB-FM rebroadcasts programming of CBN, although it is owned by the Burgeo Broadcasting System.
In March 2016, The CBC made the decision to put a nested rebroadcaster in St. John's. It would broadcast at 88.5 MHz with an ERP of 3,612 Watts. On July 5, 2016, the station went on-air for testing. On August 1, 2016, the CRTC approved the decision to put a nested rebroadcaster in St. John's. CBN-1-FM began broadcasting on October 28, 2016.
