Narrative:

We were approaching airport from northwest. We were originally assigned runway 18L. We were then reassigned runway 18R. I put new ILS frequency in radio standby position but did not move it to active. Captain's radio was set to runway 18R. Captain was looking for airport and didn't see me fly through runway 18R localizer. I didn't notice I had runway 18L frequency in active mode. ATC noticed my flying through the runway 18R localizer and gave us vectors to reintercept. There was no conflict with other traffic. To prevent reoccurrence, make sure ILS is properly idented, especially at home airport where all idents are familiar, and in this case taken for granted as being correct.

Title: A CL65 FLC FLIES THROUGH THE LOC OF RWY 18L AFTER RECEIVING A RWY CHANGE TO RWY 18R AT CVG, KY.

Narrative: WE WERE APCHING ARPT FROM NW. WE WERE ORIGINALLY ASSIGNED RWY 18L. WE WERE THEN REASSIGNED RWY 18R. I PUT NEW ILS FREQ IN RADIO STANDBY POS BUT DID NOT MOVE IT TO ACTIVE. CAPT'S RADIO WAS SET TO RWY 18R. CAPT WAS LOOKING FOR ARPT AND DIDN'T SEE ME FLY THROUGH RWY 18R LOC. I DIDN'T NOTICE I HAD RWY 18L FREQ IN ACTIVE MODE. ATC NOTICED MY FLYING THROUGH THE RWY 18R LOC AND GAVE US VECTORS TO REINTERCEPT. THERE WAS NO CONFLICT WITH OTHER TFC. TO PREVENT REOCCURRENCE, MAKE SURE ILS IS PROPERLY IDENTED, ESPECIALLY AT HOME ARPT WHERE ALL IDENTS ARE FAMILIAR, AND IN THIS CASE TAKEN FOR GRANTED AS BEING CORRECT.
