Narrative:
Arrived in memphis area, told to expect runway 36R. Approach was briefed, and then radios set for approach. We were then given a vector away from the airport and were told to expect runway 36L. We took out new approach plates and began to brief an approach for runway 36L. We were given multiple dscnts, heading and speed changes over the next couple of mins. We were also distraction by an autoplt disconnect. We were given a final vector to intercept the ILS for runway 36L at 4000 ft AGL. We set the autoplt for the approach, but the autoplt disconnected again. Approach asked us where we were going then gave us an immediate vector away from the field. We finally noticed we were on the wrong ILS frequency despite briefing the correct frequency. A contributing factor was the company's approved approach checklist does not include checking radio frequency.

Title: B727 FLC MISTAKENLY TUNED IN THE WRONG ILS FREQ RESULTING IN APCH CTLR INTERVENTION AND VECTORS TO THE INTENDED ILS APCH.
Narrative: ARRIVED IN MEMPHIS AREA, TOLD TO EXPECT RWY 36R. APCH WAS BRIEFED, AND THEN RADIOS SET FOR APCH. WE WERE THEN GIVEN A VECTOR AWAY FROM THE ARPT AND WERE TOLD TO EXPECT RWY 36L. WE TOOK OUT NEW APCH PLATES AND BEGAN TO BRIEF AN APCH FOR RWY 36L. WE WERE GIVEN MULTIPLE DSCNTS, HDG AND SPD CHANGES OVER THE NEXT COUPLE OF MINS. WE WERE ALSO DISTR BY AN AUTOPLT DISCONNECT. WE WERE GIVEN A FINAL VECTOR TO INTERCEPT THE ILS FOR RWY 36L AT 4000 FT AGL. WE SET THE AUTOPLT FOR THE APCH, BUT THE AUTOPLT DISCONNECTED AGAIN. APCH ASKED US WHERE WE WERE GOING THEN GAVE US AN IMMEDIATE VECTOR AWAY FROM THE FIELD. WE FINALLY NOTICED WE WERE ON THE WRONG ILS FREQ DESPITE BRIEFING THE CORRECT FREQ. A CONTRIBUTING FACTOR WAS THE COMPANY'S APPROVED APCH CHKLIST DOES NOT INCLUDE CHKING RADIO FREQ.
