Narrative:

We took off from dfw on runway 18L (west side of field, with west tower frequency 124.15). Our instructions prior to takeoff were to fly heading 155 degrees after takeoff (a 19 degree left turn from runway heading). Cleared for takeoff. At 400 ft afe, I began a shallow left turn to 155 degrees. Just as I rolled out on 155 degrees, tower controller came on with a sense of urgency directing us to turn right to 190 degrees. We did so and then noted both visually and on TCASII, an MD80 who had taken off from the east side of the field (different tower frequency). It would appear that the 2 tower controllers did not coordinate their actions well as our controller had given us a heading which was going to constantly reduce the lateral separation between us. No TCASII warning of any kind (TA or RA) occurred. In large part, this problem was controller induced. I did have to ask myself if there was anything I could have done to prevent the controller's error from going as far as it did. I believe if I had asked the captain if we were clear left before I started my turn at 400 ft afe, that the captain would have seen the MD80 and questioned the controller before turning. Another lesson learned.

Title: B737-300 CREW WAS GIVEN A HEADING AFTER TKOF THAT TURNED THE ACFT INTO A DEPARTING MD80 TAKING OFF ON A PARALLEL RWY AT DFW.

Narrative: WE TOOK OFF FROM DFW ON RWY 18L (W SIDE OF FIELD, WITH W TWR FREQ 124.15). OUR INSTRUCTIONS PRIOR TO TKOF WERE TO FLY HEADING 155 DEGS AFTER TKOF (A 19 DEG L TURN FROM RWY HEADING). CLRED FOR TKOF. AT 400 FT AFE, I BEGAN A SHALLOW L TURN TO 155 DEGS. JUST AS I ROLLED OUT ON 155 DEGS, TWR CTLR CAME ON WITH A SENSE OF URGENCY DIRECTING US TO TURN R TO 190 DEGS. WE DID SO AND THEN NOTED BOTH VISUALLY AND ON TCASII, AN MD80 WHO HAD TAKEN OFF FROM THE E SIDE OF THE FIELD (DIFFERENT TWR FREQ). IT WOULD APPEAR THAT THE 2 TWR CTLRS DID NOT COORDINATE THEIR ACTIONS WELL AS OUR CTLR HAD GIVEN US A HEADING WHICH WAS GOING TO CONSTANTLY REDUCE THE LATERAL SEPARATION BTWN US. NO TCASII WARNING OF ANY KIND (TA OR RA) OCCURRED. IN LARGE PART, THIS PROB WAS CTLR INDUCED. I DID HAVE TO ASK MYSELF IF THERE WAS ANYTHING I COULD HAVE DONE TO PREVENT THE CTLR'S ERROR FROM GOING AS FAR AS IT DID. I BELIEVE IF I HAD ASKED THE CAPT IF WE WERE CLR L BEFORE I STARTED MY TURN AT 400 FT AFE, THAT THE CAPT WOULD HAVE SEEN THE MD80 AND QUESTIONED THE CTLR BEFORE TURNING. ANOTHER LESSON LEARNED.
