Narrative:

We were flying a routine cargo flight between myf and hhr. We were in radar contact with ATC at the time getting VFR flight following. It was approximately XX30 PDT and we were 10 NM south of sna at 4500 ft. We had no assigned altitude, no assigned heading, and no traffic was called to us. We looked to our right at about 3 O'clock position and saw a fast moving, climbing airliner. We started a descent to avoid collision with the jet. We knew that we couldn't out-climb the jet so we decided to descend. We heard ATC arguing with air carrier about what altitude we were at so we couldn't transmit. After that ATC asked us if we saw the air carrier jet and we told them why we descended. It would have been better if ATC called the air carrier jet out to us. We would have known what altitude the jet was climbing to.

Narrative: WE WERE FLYING A ROUTINE CARGO FLT BTWN MYF AND HHR. WE WERE IN RADAR CONTACT WITH ATC AT THE TIME GETTING VFR FLT FOLLOWING. IT WAS APPROX XX30 PDT AND WE WERE 10 NM S OF SNA AT 4500 FT. WE HAD NO ASSIGNED ALT, NO ASSIGNED HEADING, AND NO TFC WAS CALLED TO US. WE LOOKED TO OUR R AT ABOUT 3 O'CLOCK POS AND SAW A FAST MOVING, CLBING AIRLINER. WE STARTED A DSCNT TO AVOID COLLISION WITH THE JET. WE KNEW THAT WE COULDN'T OUT-CLB THE JET SO WE DECIDED TO DSND. WE HEARD ATC ARGUING WITH ACR ABOUT WHAT ALT WE WERE AT SO WE COULDN'T XMIT. AFTER THAT ATC ASKED US IF WE SAW THE ACR JET AND WE TOLD THEM WHY WE DSNDED. IT WOULD HAVE BEEN BETTER IF ATC CALLED THE ACR JET OUT TO US. WE WOULD HAVE KNOWN WHAT ALT THE JET WAS CLBING TO.
