Narrative:

In cruise at 8000 ft when my first officer says 'look at that,' I saw an aircraft in a slight bank to the south, could not tell whether aircraft was opposite or same direction at first. I disconnected the autoplt, in case action was required, and then I could tell that the aircraft was opposite direction and exactly our altitude on a converging course in a right bank (shallow). The aircraft's bank angle appeared not enough so I banked right abruptly to a 30 degree angle and climbed 100 ft. The ont controller had not heard our chkin and had started calling us asking us to descend, but by that time the small aircraft was past us, approximately 500-1000 ft horizontally. The controller said that the small aircraft wasn't talking to anyone and that no n- number was available. The pdz VOR/DME is a high density traffic area with en route carrier traffic and departures off ont cross the fix. I personally would like to see inbound aircraft to lax from psp, ca, kept higher due to the high number of GA aircraft over this fix, both en route and instruction aircraft. This is the second time that I've taken evasive over pdz. We're en route from psp to lax and yes, the passenger did notice all of them.

Title: LTT HAS CONFLICT WITH AN SMA IN VICINITY OF PDZ.

Narrative: IN CRUISE AT 8000 FT WHEN MY FO SAYS 'LOOK AT THAT,' I SAW AN ACFT IN A SLIGHT BANK TO THE S, COULD NOT TELL WHETHER ACFT WAS OPPOSITE OR SAME DIRECTION AT FIRST. I DISCONNECTED THE AUTOPLT, IN CASE ACTION WAS REQUIRED, AND THEN I COULD TELL THAT THE ACFT WAS OPPOSITE DIRECTION AND EXACTLY OUR ALT ON A CONVERGING COURSE IN A R BANK (SHALLOW). THE ACFT'S BANK ANGLE APPEARED NOT ENOUGH SO I BANKED R ABRUPTLY TO A 30 DEG ANGLE AND CLBED 100 FT. THE ONT CTLR HAD NOT HEARD OUR CHKIN AND HAD STARTED CALLING US ASKING US TO DSND, BUT BY THAT TIME THE SMA WAS PAST US, APPROX 500-1000 FT HORIZLY. THE CTLR SAID THAT THE SMA WASN'T TALKING TO ANYONE AND THAT NO N- NUMBER WAS AVAILABLE. THE PDZ VOR/DME IS A HIGH DENSITY TFC AREA WITH ENRTE CARRIER TFC AND DEPS OFF ONT CROSS THE FIX. I PERSONALLY WOULD LIKE TO SEE INBOUND ACFT TO LAX FROM PSP, CA, KEPT HIGHER DUE TO THE HIGH NUMBER OF GA ACFT OVER THIS FIX, BOTH ENRTE AND INSTRUCTION ACFT. THIS IS THE SECOND TIME THAT I'VE TAKEN EVASIVE OVER PDZ. WE'RE ENRTE FROM PSP TO LAX AND YES, THE PAX DID NOTICE ALL OF THEM.
