Narrative:

First officer flying pullman arrival to ord. Given clearance to cross pivot at 11000 ft and 320 KTS. At pivot, given descent to 8000 ft and 210 KTS. Passing through 9000 ft at 210 KTS, given descent to 7000 ft, 230 KTS, intercept localizer runway 22R, on present heading (257 degrees). I conducted a brief for runway 22R, but it was disjointed due to frequent revisions by ATC. In the process I failed to brief the runway 22R localizer frequency. As I slowed the aircraft the captain set the runway 22L localizer frequency. And idented it (using the runway 22L approach plate). I set the runway 22R localizer course and proceeded to intercept it. ATC caught our mistake abeam felux and vectored us to runway 22R. In retrospect I believe a complete approach brief with ILS frequency would have alerted me to the erroneous frequency dialed in. 99 percent of the time I set my own radios, but given the higher than normal workload I welcomed the assistance. Miles out might have lulled me into a false sense of security (hence my failure to xchk the localizer frequency).

Narrative: FO FLYING PULLMAN ARR TO ORD. GIVEN CLRNC TO CROSS PIVOT AT 11000 FT AND 320 KTS. AT PIVOT, GIVEN DSCNT TO 8000 FT AND 210 KTS. PASSING THROUGH 9000 FT AT 210 KTS, GIVEN DSCNT TO 7000 FT, 230 KTS, INTERCEPT LOC RWY 22R, ON PRESENT HDG (257 DEGS). I CONDUCTED A BRIEF FOR RWY 22R, BUT IT WAS DISJOINTED DUE TO FREQUENT REVISIONS BY ATC. IN THE PROCESS I FAILED TO BRIEF THE RWY 22R LOC FREQ. AS I SLOWED THE ACFT THE CAPT SET THE RWY 22L LOC FREQ. AND IDENTED IT (USING THE RWY 22L APCH PLATE). I SET THE RWY 22R LOC COURSE AND PROCEEDED TO INTERCEPT IT. ATC CAUGHT OUR MISTAKE ABEAM FELUX AND VECTORED US TO RWY 22R. IN RETROSPECT I BELIEVE A COMPLETE APCH BRIEF WITH ILS FREQ WOULD HAVE ALERTED ME TO THE ERRONEOUS FREQ DIALED IN. 99 PERCENT OF THE TIME I SET MY OWN RADIOS, BUT GIVEN THE HIGHER THAN NORMAL WORKLOAD I WELCOMED THE ASSISTANCE. MILES OUT MIGHT HAVE LULLED ME INTO A FALSE SENSE OF SECURITY (HENCE MY FAILURE TO XCHK THE LOC FREQ).
