CL65 CREW HAD TRACK DEV ON ARR AT CVG.

Narrative

WE WERE BEING VECTORED FOR AN ILS RWY 18R INTO CVG. WE WERE RECEIVING NUMEROUS SMALL TURNS AND FAIRLY FREQUENT DSCNTS. I TUNED THE LOC INTO THE STANDBY POS. WHEN WE WERE STARTED ON THE VECTOR; I THOUGHT I XFERRED THE LOC TO THE PRIMARY POS. I EITHER FORGOT TO DO IT OR PUSHED THE XFER BUTTON AND IT DIDN'T CHANGE BECAUSE I DIDN'T HAVE THE LOC FREQ TUNED WHEN WE WERE CLRED FOR THE APCH. THE FO RAN THE DSCNT AND APCH CHKLIST; WHICH CALLS FOR CHKING THE IDENT ON THE APCH NAVAID FREQ. HE RESPONDED THAT THE RADIOS WERE TUNED AND IDENTED INDICATING A DOUBLECHK OF THE PROPER LOC FREQ. AFTER THE FACT; HE FELT THAT HE MUST HAVE INADVERTENTLY IDENTED HIS PROPERLY TUNED RADIO TWICE. BECAUSE OF THIS; HE MISSED THAT I HAD THE WRONG FREQ TUNED. WE WERE GIVEN OUR INTERCEPT HDG AND CLRED FOR THE ILS RWY 18R. I REALIZED WE WERE TAKING TOO LONG TO JOIN AND FOUND THE PROB JUST AS APCH CTL WAS ASKING IF WE WERE GOING THROUGH FINAL. I WAS IN THE R TURN WHEN HE GAVE US 220 DEGS TO REJOIN. THE LOC WAS OFF THE PEG AND WE WERE 3/4 DEFLECTION WHEN HE GAVE US A TURN TO 270 DEGS AND CLB TO 3000 FT. HE ALSO GAVE ANOTHER ACFT A TURN. I THINK THE OTHER ACFT WAS BEHIND US; WE NEVER GOT A TCASII WARNING; BUT I DON'T KNOW IF THE CTLR LOST SEPARATION. HE NEVER ASKED US TO CALL THE SUPVR. ON OUR SECOND APCH WE APOLOGIZED FOR THE PROB AND HE SAID IT WAS OK. SOME HUMAN FACTORS MAY HAVE BEEN IN PLAY FOR ME. I JUST FINISHED A 2-DAY TRIP WITH EARLY MORNING WAKE-UPS; WHICH I DON'T LIKE. I WAS TIRED. MY UNCLE HAD JUST DIED AND HE WAS A GREAT UNCLE THAT WE ALL THOUGHT WOULD RECOVER FROM HIS SURGERY. I HAD JUST HAD A SCARE WITH A POSSIBLE KIDNEY STONE THAT THANKFULLY TURNED OUT TO BE A CALCIFICATION OF THE SPLEEN. I THOUGHT I WAS FIT TO FLY; AND I'M STILL NOT SURE THAT I WASN'T. BUT THESE MAY HAVE BEEN CONTRIBUTING FACTORS.
