Narrative:

On IFR departure several TCASII targets appeared as we turned to heading 350 degrees to intercept V15 (310 degree radial). The first target was not a conflict, passing well to our left. As we climbed above 1000 ft AGL, we received another TA TCASII warning. The traffic (2 closely-spaced targets) were at 12 O'clock and closing fast. They appeared to be at our altitude. We passed traffic in climb at takeoff thrust, ATC (tower) said he had 'no traffic' for us prior to our passing. When I asked him about targets approximately 2 mi ahead, the TA altitude readout was +/-200 ft (vertical) when we passed the targets. No RA ever issued. We were in moderate rain, with nose up in climb. Never saw any traffic, only evasive action was maintaining takeoff thrust to climb above. When switching to departure frequency, controller admitted 2 helicopters came quite close inbound towards airport, not working his frequency. This is class D airspace -- they were maybe outside 4 mi -- legal? But tour helicopters should be vigilant to avoid our air carrier traffic by a wider margin.

Title: THE FLC OF A B737-200 HAS TCASII TA AFTER DEP WITH TFC APPEARING TO BE AT SAME ALT. THEY CLB WITH FULL PWR TO MISS THE TFC. ATC SAYS THERE IS NO TFC. SWITCHING TO DEP CTL THEY ARE INFORMED THAT THERE WERE 2 TOUR HELIS WHO WERE NOT IN COM WITH THE TWR.

Narrative: ON IFR DEP SEVERAL TCASII TARGETS APPEARED AS WE TURNED TO HDG 350 DEGS TO INTERCEPT V15 (310 DEG RADIAL). THE FIRST TARGET WAS NOT A CONFLICT, PASSING WELL TO OUR L. AS WE CLBED ABOVE 1000 FT AGL, WE RECEIVED ANOTHER TA TCASII WARNING. THE TFC (2 CLOSELY-SPACED TARGETS) WERE AT 12 O'CLOCK AND CLOSING FAST. THEY APPEARED TO BE AT OUR ALT. WE PASSED TFC IN CLB AT TKOF THRUST, ATC (TWR) SAID HE HAD 'NO TFC' FOR US PRIOR TO OUR PASSING. WHEN I ASKED HIM ABOUT TARGETS APPROX 2 MI AHEAD, THE TA ALT READOUT WAS +/-200 FT (VERT) WHEN WE PASSED THE TARGETS. NO RA EVER ISSUED. WE WERE IN MODERATE RAIN, WITH NOSE UP IN CLB. NEVER SAW ANY TFC, ONLY EVASIVE ACTION WAS MAINTAINING TKOF THRUST TO CLB ABOVE. WHEN SWITCHING TO DEP FREQ, CTLR ADMITTED 2 HELIS CAME QUITE CLOSE INBOUND TOWARDS ARPT, NOT WORKING HIS FREQ. THIS IS CLASS D AIRSPACE -- THEY WERE MAYBE OUTSIDE 4 MI -- LEGAL? BUT TOUR HELIS SHOULD BE VIGILANT TO AVOID OUR ACR TFC BY A WIDER MARGIN.
