Narrative:

We departed on runway 35L from tulsa and contacted departure control. We then made a series of left turns as instructed to a heading of 190 to intercept the tulsa 185 radial climbing to an assigned altitude of FL230. Just south of tulsa passing 10000' in the climb we had a near miss with a blue turbo small transport level at 10500'. The other aircraft was first sighted at a distance of 500-1000' moving from our left rear and slightly above. I initiated a 30 degree left bank and a 1-2g pushover. Miss distance was 200-250' with the other aircraft passing slightly above and to our right. No traffic had been called by departure control. We immediately reported the near miss and were then told by departure that they had a target in our location at 10400'. After landing I called tulsa departure. The controller said that the aircraft was tracked to okc and the pilot contacted. The other pilot stated that he had no idea that a near miss had occurred. He was on a VFR flight plan from oma to okc and was not in contact with any controling agency. The tulsa controller said that due to numerous VFR targets in the area of the near miss that aircraft squawking XXXX had been filtered out. I feel there was no way we could have seen the other aircraft sooner, since he was approaching us from above and to our left rear. The other pilot would probably not have been able to see us, since he was looking across the cockpit and we were climbing from below and behind him. Our airspeed was 250 KTS and rate of climb around 2000 FPM. My only recommendations are that pilots flying high performance aircraft should be in contact with some controling agency, and that departure control should not filter out XXXX squawks in jet climb corridors.

Title: CLOSE PROX ACR-MLG GA-SMT NEAR TUL VOR ABOVE THE TRSA.

Narrative: WE DEPARTED ON RWY 35L FROM TULSA AND CONTACTED DEP CTL. WE THEN MADE A SERIES OF LEFT TURNS AS INSTRUCTED TO A HDG OF 190 TO INTERCEPT THE TULSA 185 RADIAL CLIMBING TO AN ASSIGNED ALT OF FL230. JUST S OF TULSA PASSING 10000' IN THE CLIMB WE HAD A NEAR MISS WITH A BLUE TURBO SMT LEVEL AT 10500'. THE OTHER ACFT WAS FIRST SIGHTED AT A DISTANCE OF 500-1000' MOVING FROM OUR LEFT REAR AND SLIGHTLY ABOVE. I INITIATED A 30 DEG LEFT BANK AND A 1-2G PUSHOVER. MISS DISTANCE WAS 200-250' WITH THE OTHER ACFT PASSING SLIGHTLY ABOVE AND TO OUR RIGHT. NO TFC HAD BEEN CALLED BY DEP CTL. WE IMMEDIATELY REPORTED THE NEAR MISS AND WERE THEN TOLD BY DEP THAT THEY HAD A TARGET IN OUR LOCATION AT 10400'. AFTER LNDG I CALLED TULSA DEP. THE CTLR SAID THAT THE ACFT WAS TRACKED TO OKC AND THE PLT CONTACTED. THE OTHER PLT STATED THAT HE HAD NO IDEA THAT A NEAR MISS HAD OCCURRED. HE WAS ON A VFR FLT PLAN FROM OMA TO OKC AND WAS NOT IN CONTACT WITH ANY CTLING AGENCY. THE TULSA CTLR SAID THAT DUE TO NUMEROUS VFR TARGETS IN THE AREA OF THE NEAR MISS THAT ACFT SQUAWKING XXXX HAD BEEN FILTERED OUT. I FEEL THERE WAS NO WAY WE COULD HAVE SEEN THE OTHER ACFT SOONER, SINCE HE WAS APCHING US FROM ABOVE AND TO OUR LEFT REAR. THE OTHER PLT WOULD PROBABLY NOT HAVE BEEN ABLE TO SEE US, SINCE HE WAS LOOKING ACROSS THE COCKPIT AND WE WERE CLIMBING FROM BELOW AND BEHIND HIM. OUR AIRSPEED WAS 250 KTS AND RATE OF CLIMB AROUND 2000 FPM. MY ONLY RECOMMENDATIONS ARE THAT PLTS FLYING HIGH PERFORMANCE ACFT SHOULD BE IN CONTACT WITH SOME CTLING AGENCY, AND THAT DEP CTL SHOULD NOT FILTER OUT XXXX SQUAWKS IN JET CLIMB CORRIDORS.
