Narrative:

During a practice NDB approach into ccr, the controllers issued us a vector of 270 degrees for radar vectors to the final approach course. After turning to 270 degrees, I realized that we would not be able to maintain VFR on that heading and we turned to 210 degrees to maintain VFR. After turning, we tried twice to contact the controller and he was stepped on. This frequency (119.9) was very congested with what sounded like aircraft requesting VFR advisories. A short time after our second attempt to contact approach, the controller came back on and asked us what heading we were flying, and we advised him of 210 degrees. This created no problem, although the approach did seem upset with the heading change. Some contributing factors were the congested frequency and our inability to contact approach to advise them of the heading change. Callback conversation with reporter revealed the following: asked reporter if he had been instructed to maintain VFR when approach control agreed to his practice NDB approach. He was a little reluctant to answer until analyst explained that if he had been so instructed, turning as he did was proper. On the other hand, if he had not, he was in effect on an IFR flight plan and should not have turned. He said he thought he had been instructed to maintain VFR.

Title: STUDENT INSTRUCTOR TURN FROM ASSIGNED HEADING IN ORDER TO REMAIN VFR.

Narrative: DURING A PRACTICE NDB APCH INTO CCR, THE CTLRS ISSUED US A VECTOR OF 270 DEGS FOR RADAR VECTORS TO THE FINAL APCH COURSE. AFTER TURNING TO 270 DEGS, I REALIZED THAT WE WOULD NOT BE ABLE TO MAINTAIN VFR ON THAT HDG AND WE TURNED TO 210 DEGS TO MAINTAIN VFR. AFTER TURNING, WE TRIED TWICE TO CONTACT THE CTLR AND HE WAS STEPPED ON. THIS FREQ (119.9) WAS VERY CONGESTED WITH WHAT SOUNDED LIKE ACFT REQUESTING VFR ADVISORIES. A SHORT TIME AFTER OUR SECOND ATTEMPT TO CONTACT APCH, THE CTLR CAME BACK ON AND ASKED US WHAT HDG WE WERE FLYING, AND WE ADVISED HIM OF 210 DEGS. THIS CREATED NO PROB, ALTHOUGH THE APCH DID SEEM UPSET WITH THE HDG CHANGE. SOME CONTRIBUTING FACTORS WERE THE CONGESTED FREQ AND OUR INABILITY TO CONTACT APCH TO ADVISE THEM OF THE HDG CHANGE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: ASKED RPTR IF HE HAD BEEN INSTRUCTED TO MAINTAIN VFR WHEN APCH CTL AGREED TO HIS PRACTICE NDB APCH. HE WAS A LITTLE RELUCTANT TO ANSWER UNTIL ANALYST EXPLAINED THAT IF HE HAD BEEN SO INSTRUCTED, TURNING AS HE DID WAS PROPER. ON THE OTHER HAND, IF HE HAD NOT, HE WAS IN EFFECT ON AN IFR FLT PLAN AND SHOULD NOT HAVE TURNED. HE SAID HE THOUGHT HE HAD BEEN INSTRUCTED TO MAINTAIN VFR.
