In 1976, Radio CKPT 1420 Ltd. (a division of CHUM Limited), received CRTC approval to operate a new commercial FM station at Peterborough. It would broadcast on a frequency of 105.1 MHz and have an effective radiated power of 50,000 watts (horizontal & vertical). The station was launched on September 16, 1977, with a MOR format. The "QM" in CKQM-FM's call sign stood for "Quality Music".
In October 1983, CKQM switched to a country format, becoming Country 105.
On May 13, 2011, the CRTC denied an application to increase the station's effective radiated power from 7,500 watts to 14,000 watts (non-directional), citing that CTVglobemedia failed to demonstrate that the station's existing coverage was inadequate in Peterborough.[3]
Logo as Pure Country 105, 2019-2025
On May 28, 2019, the station rebranded as Pure Country as part of a national rebranding of all Bell Media country stations.[4]
On February 8, 2024, Bell announced that it would sell 45 of its radio stations as part of cuts, with CKQM and CKPT-FM being sold to Durham Radio.[5][6] On January 30, 2025, the CRTC approved the sale to Durham.[7]
On May 5, 2025, Durham Radio rebranded the station as KX 105, with no change in format; the new branding is modelled after its new sister stations CJKX-FM in Ajax and CHKX-FM in Hamilton. CKQM also changed its call letters to CKXP-FM to match the "KX" branding.[8]
