Narrative:

For a period of 1 week V12 from bible grove VOR to shelbyville VOR, the changeover point on the airway, was not reliable. Weak signals, especially from shelbyville VOR. I reported the problem to center after they asked me if I was on course. Solution: check vors after pilot report unreliable signals.
