 In September 2006, CFCY made its switch to FM with permission to simulcast the new station on the old 630 AM signal for 90 days and to cease operations on the AM signal afterwards.In December 2006, the audio feed for CFCY-AM at 630 has ceased operations.However, an open carrier remained on the air at 630 AM which had some wondering if it was CFCY-AM or a pirate taking over the FM frequency.
