The station originally began broadcasting as CJNH in 1975, on the AM band at 1240kHz and partially rebroadcasting CJBQ in Belleville, and CJTN in Trenton, to the south.
On December 13, 1984, the CRTC approved a number of applications for a number of AM radio stations across Ontario including CJNH Bancroft to increase their nighttime power from 250 watts to 1,000 watts. [1]
CJNH was given approval by the CRTC on March 2, 2001 to convert to FM,[2] and moved to the FM band at 97.7 FM in May 2001 with the new callsign CHMS-FM.
On April 23, 2012 Vista Broadcast Group, which owns a number of radio stations in western Canada, announced a deal to acquire Haliburton Broadcasting Group, in cooperation with Westerkirk Capital.[3] The transaction was approved by the CRTC on October 19, 2012.[4]
