Narrative:

Acy VOR southwest quadrant courses cause considerable scalloping at 40-15 DME. Condition has persisted for a long time. Normal procedure is just to ignore most needle swings and hold a heading that will average the swings. At about 15 DME southwest ATC advises we are 5 NM off course and issues heading to fly direct. I have personally reported this NAVAID problem on at least three separate occasions.
