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 March 24, 2009, CKQM received approval by the CRTC to decrease the effective radiated power from 50,000 watts to 7,500 watts, and increasing
height above average terrain from 91.5 to 277.5 meters. In
FM Broadcasting,
effective radiated power is
Inversely proportional to
antenna height. 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. On May 28, 2019, the station rebranded as
Pure Country as part of a national rebranding of all
Bell Media country stations. 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. On January 30, 2025, the CRTC approved the sale to Durham. 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.'''' ==References==
