Narrative:

Rdu approach control was working 2 frequencys -- 1 was 128.3, the one we were on. Our flight was being vectored for a visual approach to runway 5R at rdu. At 4000 ft, about 12 mi from the airport, approach gave us a 320 degree heading. After reading back 320 degree heading 4000 ft, the captain turned to heading 320 degrees for about 30 seconds. Later, ATC came back and said that heading was for someone else on the frequency and had us turn to a 180 degree heading. After reading that back, the captain turned to that heading. After just a couple more vectors, we landed visually at rdu. We believe the cause of this problem was ATC using 2 frequencys and not correcting us when we read back the heading of 320 degrees. End of statement.
