Narrative:
We were level at 4000', assigned heading 330 degrees by coast departure. A single engine aircraft (small aircraft) crossed directly in front of us at our altitude. First officer saw aircraft first, as it appeared from behind my windshield post I saw it within a fraction of a second after him and turned left quickly to avoid. There was no warning from ATC whatsoever. Due to congestion on the frequency, we were unable to question the controller about the target, whether it was on his screen. The aircraft we almost hit looked brand new, so I would be surprised if it didn't have a transponder. We have had a # of cases lately where there was close traffic not called by ATC.

Title: SMT ACR HAD NMAC WITH SMA AT 4000' MSL NEAR ANAHEIM, CA. NO TRAFFIC ADVISORY.
Narrative: WE WERE LEVEL AT 4000', ASSIGNED HDG 330 DEGS BY COAST DEP. A SINGLE ENG ACFT (SMA) CROSSED DIRECTLY IN FRONT OF US AT OUR ALT. F/O SAW ACFT FIRST, AS IT APPEARED FROM BEHIND MY WINDSHIELD POST I SAW IT WITHIN A FRACTION OF A SECOND AFTER HIM AND TURNED LEFT QUICKLY TO AVOID. THERE WAS NO WARNING FROM ATC WHATSOEVER. DUE TO CONGESTION ON THE FREQ, WE WERE UNABLE TO QUESTION THE CTLR ABOUT THE TARGET, WHETHER IT WAS ON HIS SCREEN. THE ACFT WE ALMOST HIT LOOKED BRAND NEW, SO I WOULD BE SURPRISED IF IT DIDN'T HAVE A XPONDER. WE HAVE HAD A # OF CASES LATELY WHERE THERE WAS CLOSE TFC NOT CALLED BY ATC.
