CKRU-FM

CKRU-FM is a Canadian radio station broadcasting at 100.5 FM in Peterborough, Ontario, owned by Corus Entertainment. The station broadcasts a hot adult contemporary format branded as 100.5 Fresh Radio.

History

The station began broadcasting back in 1942 as CHEX at AM 1430 kHz, until it moved to 980 kHz in 1958. CHEX became CKRU in 1992. The CHEX call letters currently belong to CHEX-TV in Peterborough.

Switch to FM

On October 11, 2007, CKRU applied to the Canadian Radio-television and Telecommunications Commission (CRTC) to convert from the AM band to the FM band.

On May 8, 2008, CKRU was given approval to convert to the FM band at 96.7 MHz, however, Pineridge Broadcasting, who owns CKSG-FM and CHUC-FM in Cobourg, Ontario, had selected the 96.7 FM frequency for a new adult contemporary station. As a result, CKRU had to then do research to find another FM frequency, and applied to broadcast at 100.5 FM. This application to convert CKRU from 980 AM to 100.5 FM was approved on December 1, 2008. On December 23, 2008, the licensee proposed to change the authorized contours by decreasing the average effective radiated power from 50,000 watts to 7,500 watts.
