Narrative:

As the controller working dallas south position gave the tower controller automatic releases for departure off of dfw. I, at the time, had traffic working in the pattern at nbe naval air station. Departures off of dfw runway 13L penetrate the airspace for nbe traffic. So to reduce coordination for individual releases, I displayed the nbe traffic to the tower's radar and advised tower nbe traffic 12 mi southeast of dfw is mlt Y, reference this traffic continue with automatic releases. Small transport X departed runway 13L on wrong transponder code. I called tower to identify said aircraft and to advise tower that I was not in radio contact and to turn small transport X heading 040 degree to miss mlt Y. Tower then advised me she was not talking to small transport X. I then transmitted in the blind to small transport X and no response. At this time, I called nbe gca and advised the controller to watch for traffic 2 mi southeast of dfw reference. Mlt Y and that I was not talking to said traffic. Small transport X checked on my frequency 4 mi southeast of dfw level at 2000'. I then climbed small transport X immediately to 3000', but at that point loss of sep had occurred. I feel that contributing to this operational error were the following. Incorrect point-out procedures on my part. Tower's non assistance in trying to call small transport X when I was not talking to said aircraft. Small transport X where was or who was the pilot in contact with from the time tower switched him until he checked on my frequency 4 mi southeast of the airport (nearly 45 seconds)? Dfw is too busy of an environment to not be talking to anyone for 45 seconds after being airborne.

Title: SMT LATE IN MAKING FREQ CHANGE TO DEP CTL HAD LESS THAN STANDARD SEPARATION WITH MLT IN TRAFFIC PATTERN AT MIL ARPT SOUTH OF DFW.

Narrative: AS THE CTLR WORKING DALLAS S POS GAVE THE TWR CTLR AUTOMATIC RELEASES FOR DEP OFF OF DFW. I, AT THE TIME, HAD TFC WORKING IN THE PATTERN AT NBE NAVAL AIR STATION. DEPS OFF OF DFW RWY 13L PENETRATE THE AIRSPACE FOR NBE TFC. SO TO REDUCE COORD FOR INDIVIDUAL RELEASES, I DISPLAYED THE NBE TFC TO THE TWR'S RADAR AND ADVISED TWR NBE TFC 12 MI SE OF DFW IS MLT Y, REFERENCE THIS TFC CONTINUE WITH AUTOMATIC RELEASES. SMT X DEPARTED RWY 13L ON WRONG XPONDER CODE. I CALLED TWR TO IDENT SAID ACFT AND TO ADVISE TWR THAT I WAS NOT IN RADIO CONTACT AND TO TURN SMT X HDG 040 DEG TO MISS MLT Y. TWR THEN ADVISED ME SHE WAS NOT TALKING TO SMT X. I THEN XMITTED IN THE BLIND TO SMT X AND NO RESPONSE. AT THIS TIME, I CALLED NBE GCA AND ADVISED THE CTLR TO WATCH FOR TFC 2 MI SE OF DFW REFERENCE. MLT Y AND THAT I WAS NOT TALKING TO SAID TFC. SMT X CHKED ON MY FREQ 4 MI SE OF DFW LEVEL AT 2000'. I THEN CLBED SMT X IMMEDIATELY TO 3000', BUT AT THAT POINT LOSS OF SEP HAD OCCURRED. I FEEL THAT CONTRIBUTING TO THIS OPERROR WERE THE FOLLOWING. INCORRECT POINT-OUT PROCS ON MY PART. TWR'S NON ASSISTANCE IN TRYING TO CALL SMT X WHEN I WAS NOT TALKING TO SAID ACFT. SMT X WHERE WAS OR WHO WAS THE PLT IN CONTACT WITH FROM THE TIME TWR SWITCHED HIM UNTIL HE CHKED ON MY FREQ 4 MI SE OF THE ARPT (NEARLY 45 SECS)? DFW IS TOO BUSY OF AN ENVIRONMENT TO NOT BE TALKING TO ANYONE FOR 45 SECS AFTER BEING AIRBORNE.
