Narrative:

I was flying metropolitan traffic and was turning eastbound north of I-8 when south traffic passed off my left wing. I was monitoring myf tower and heard the tower hand south off to lindbergh tower for a class B clearance. I was staying north of the 084 degree radial and therefore didn't need a class B clearance. Suddenly myf tower called the traffic to me. We avoided each other. Afterwards tower said that south was in class B airspace. If south was in class B and I was south of south position, I must have been in class B. Yet my VOR, (which was checked just prior to flight) showed me clearly north of class B airspace. I'm still unsure if I encroached into class B or not but from this point forward I'm not going south of the 076 degree right without a clearance.

Title: NMAC BTWN OPPOSITE DIRECTION TFC.

Narrative: I WAS FLYING METRO TFC AND WAS TURNING EBOUND N OF I-8 WHEN S TFC PASSED OFF MY L WING. I WAS MONITORING MYF TWR AND HEARD THE TWR HAND S OFF TO LINDBERGH TWR FOR A CLASS B CLRNC. I WAS STAYING N OF THE 084 DEG RADIAL AND THEREFORE DIDN'T NEED A CLASS B CLRNC. SUDDENLY MYF TWR CALLED THE TFC TO ME. WE AVOIDED EACH OTHER. AFTERWARDS TWR SAID THAT S WAS IN CLASS B AIRSPACE. IF S WAS IN CLASS B AND I WAS S OF S POS, I MUST HAVE BEEN IN CLASS B. YET MY VOR, (WHICH WAS CHKED JUST PRIOR TO FLT) SHOWED ME CLRLY N OF CLASS B AIRSPACE. I'M STILL UNSURE IF I ENCROACHED INTO CLASS B OR NOT BUT FROM THIS POINT FORWARD I'M NOT GOING S OF THE 076 DEG R WITHOUT A CLRNC.
