FM conversions and transmitter closures

• On October 13, 2011, CBTK applied to convert CBRD 860 to 97.1 MHz.^[4][5] The application was approved on December 15, 2011.^[6] CBRD's callsign was replaced by CBTK-FM-1 once the flip occurred.
• On August 16, 2013, CBTK-FM applied to relocate CBRJ 860 to 107.3 MHz.^[7] This application was approved on October 31, 2013.^[8]
• On October 25, 2013, at the request of the CBC, the CRTC deleted low-power AM transmitter CBKR 740 in Parson.^[9] Also, another low-power AM transmitter CBWD 900 in Donald was deleted. Radio One programming in these communities are available from adjacent transmitters CBUQ-FM and CBXE-FM, the closest Radio One transmitters to Parson and Donald.
• On September 23, 2014, the CBC was approved to convert CBUI 740 to 102.5 MHz.^[10]
• On September 1, 2017, the CBC applied to convert CBUM 900 to 91.3 MHz.^[11] The CRTC approved the CBC's application to convert CBUM to 91.3 FM on November 17, 2017.^[12] This was later changed to 99.9 MHz after the CRTC approved the CBC's application to move CBUM-FM to 99.9 MHz on September 18, 2019.^[13]

Split of CBYK-FM into separate network

CBTK-FM was previously repeated on CBYK-FM Kamloops and on 22 CBC radio repeaters in the Thompson and Cariboo regions. On October 28, 2011, the CBC filed an application with the CRTC to convert CBYK-FM to an anchor of a new regional CBC Radio One network. The CRTC approved the new regional network on March 30, 2012,^[14] with a start-up date slated for October 9, 2012.^[15][16]

CBUC-FM, which was originally to have been part of the new network, will remain a repeater of CBTK-FM, following interventions from various parties, including the City of Salmon Arm, that the region is more economically tied with the Okanagan region than with Kamloops.^[14]

Shortly after CBYK-FM's launch as a separate station, residents of Revelstoke complained to the CRTC that they were not consulted by the CBC when they switched their local repeater, CBTO-FM 91.3, to CBYK-FM's programming; e-mails made to the city's mayor's office show that 80% of listeners prefer programming from Kelowna, while only 20% prefer the new Kamloops programming. The CRTC later said that it is up to the CBC to decide which programming originates for CBTO-FM, not the CRTC. After city officials contacted the CBC, BC spokesperson Lorna Haeber said that the CBC would make a decision on the issue "shortly", but failed to elaborate how or when the decision will be made.^[17] The CRTC subsequently issued a notice that it had approved an application by the CBC to change the local programming source of its Radio One transmitter in Revelstoke from Kamloops back to Kelowna.^[18] The change was implemented on January 2, 2014.^[19]
