Narrative:
On departure immediately after takeoff, no DME was received from ieza per departure procedure. Iewr was tuned and tower advised change to departure. On change to departure, the frequency was very congested and cockpit workload was high. Departure directed us to turn left heading 230 degrees and climb and maintain what we thought was 3000 ft (which turned out to be 6000 ft, which I may have read back). On leveloff at 3000 ft cockpit tasking was high. Departure requested an expedite to 6000 ft, which was followed shortly by a TCASII TA. Traffic initially appeared to be at the 12 O'clock position and 800 ft below outside of 5 NM. At 5 NM, traffic was 1000 ft below. Climb was expedited to 6000 ft and traffic was no longer a factor.

Title: MLG FLC LEVELED OFF EARLY ON DEP CLB DUE TO THE CAPT MISUNDERSTANDING OF THE ALT TO WHICH CLRED.
Narrative: ON DEP IMMEDIATELY AFTER TKOF, NO DME WAS RECEIVED FROM IEZA PER DEP PROC. IEWR WAS TUNED AND TWR ADVISED CHANGE TO DEP. ON CHANGE TO DEP, THE FREQ WAS VERY CONGESTED AND COCKPIT WORKLOAD WAS HIGH. DEP DIRECTED US TO TURN L HDG 230 DEGS AND CLB AND MAINTAIN WHAT WE THOUGHT WAS 3000 FT (WHICH TURNED OUT TO BE 6000 FT, WHICH I MAY HAVE READ BACK). ON LEVELOFF AT 3000 FT COCKPIT TASKING WAS HIGH. DEP REQUESTED AN EXPEDITE TO 6000 FT, WHICH WAS FOLLOWED SHORTLY BY A TCASII TA. TFC INITIALLY APPEARED TO BE AT THE 12 O'CLOCK POS AND 800 FT BELOW OUTSIDE OF 5 NM. AT 5 NM, TFC WAS 1000 FT BELOW. CLB WAS EXPEDITED TO 6000 FT AND TFC WAS NO LONGER A FACTOR.
