Narrative:

On departure level at 7000 ft MSL overhead pdz VOR got a TA on TCASII. Traffic showed -200 at 12 O'clock. Constant bearing closure. Haze visibility at 7000 ft was about 5 mi. TCASII turned to RA at approximately 2.5 mi. Still could not pick up traffic visually. Initiated climb and told departure controller. Visually picked up traffic at approximately 1 mi. It was dead ahead. Estimate closest point of approach at 400-500 ft vertical 1000 ft lateral. Had we not climbed it would have been very close. Once we got a hold of departure controller, he said he was trying to get a hold of us but another aircraft was talking on the frequency preventing him from talking to us. TCASII really did the job.

Title: FLC TOOK EVASIVE ACTION IN RESPONSE TO A TCASII 'RA.'

Narrative: ON DEP LEVEL AT 7000 FT MSL OVERHEAD PDZ VOR GOT A TA ON TCASII. TFC SHOWED -200 AT 12 O'CLOCK. CONSTANT BEARING CLOSURE. HAZE VISIBILITY AT 7000 FT WAS ABOUT 5 MI. TCASII TURNED TO RA AT APPROX 2.5 MI. STILL COULD NOT PICK UP TFC VISUALLY. INITIATED CLB AND TOLD DEP CTLR. VISUALLY PICKED UP TFC AT APPROX 1 MI. IT WAS DEAD AHEAD. ESTIMATE CLOSEST POINT OF APCH AT 400-500 FT VERT 1000 FT LATERAL. HAD WE NOT CLBED IT WOULD HAVE BEEN VERY CLOSE. ONCE WE GOT A HOLD OF DEP CTLR, HE SAID HE WAS TRYING TO GET A HOLD OF US BUT ANOTHER ACFT WAS TALKING ON THE FREQ PREVENTING HIM FROM TALKING TO US. TCASII REALLY DID THE JOB.
