Narrative:
During a flight from anc to sfo a navigation discrepancy occurred during the transition over the rogue valley VOR. During the transition, an incorrect heading of 149 degrees was initially flown instead of the correct heading of 161 degrees. I recognized the problem and was taking corrective action when ATC advised me of a heading to reintercept the course. Contributing factors include the many course changes that are required during a flight on J501 from tatoosh VOR and point reyes VOR. Possible direct routing may alleviate some of these problems.
