Narrative:

On my clearance pad I wrote 4000' initial altitude assignment and set that altitude on the altitude alerter. The clearance also read rh for vectors. Upon reaching departure runway holding area the captain reviewed the clearance and asked me to request a 15-30 degree right turn for WX avoidance. The request was made to lakeland tower, who in turn coordinated with departure a turn to 330 degree. The captain decided to go with that heading and we were cleared for takeoff. Upon departure the captain initiated the right turn. I reported on departure at 1300' and advised them we were in the turn and climbing to 4000'. The controller acknowledged, then the controller advised us of traffic at 3000', then advised assigned altitude of 2000'. The captain made an immediate power reduction to flight idle and maintained 2000'. Captain's evasive action limited our ascent to 260 degree to 2700' MSL. I spoke with the facility supervisor and discovered that there was some kind of a coordination problem between departure controllers because of the heading we were assigned. We were also given the wrong departure frequency for the heading we were assigned. When I reported on departure and called what I thought was the assigned altitude, the controller did not immediately correct us. She seemed to be more concerned about telling us about the traffic first, then correcting the altitude. At the time of our check on with departure, if the controller had made the correction, there would not have been a problem. Supplemental information from acn 127760: first officer copied clearance. Wrote 4000 for altitude. Set on alerter on 4000. After departure, first officer advised departure control we were in right turn climbing to (leaving 1300) 4000. Departure controller acknowledged, then advised of traffic at 3000. Controller advised assigned altitude was 2000. Traffic 1/2 mi at 3000. Initiated evasive action (descent) to 2000 (from 2700).

Title: CORP FLT CREW ALT DEVIATION CAUSED CLOSE PROX OF SECOND ACFT.

Narrative: ON MY CLRNC PAD I WROTE 4000' INITIAL ALT ASSIGNMENT AND SET THAT ALT ON THE ALT ALERTER. THE CLRNC ALSO READ RH FOR VECTORS. UPON REACHING DEP RWY HOLDING AREA THE CAPT REVIEWED THE CLRNC AND ASKED ME TO REQUEST A 15-30 DEG RIGHT TURN FOR WX AVOIDANCE. THE REQUEST WAS MADE TO LAKELAND TWR, WHO IN TURN COORDINATED WITH DEP A TURN TO 330 DEG. THE CAPT DECIDED TO GO WITH THAT HDG AND WE WERE CLRED FOR TKOF. UPON DEP THE CAPT INITIATED THE RIGHT TURN. I REPORTED ON DEP AT 1300' AND ADVISED THEM WE WERE IN THE TURN AND CLIMBING TO 4000'. THE CTLR ACKNOWLEDGED, THEN THE CTLR ADVISED US OF TFC AT 3000', THEN ADVISED ASSIGNED ALT OF 2000'. THE CAPT MADE AN IMMEDIATE POWER REDUCTION TO FLT IDLE AND MAINTAINED 2000'. CAPT'S EVASIVE ACTION LIMITED OUR ASCENT TO 260 DEG TO 2700' MSL. I SPOKE WITH THE FAC SUPVR AND DISCOVERED THAT THERE WAS SOME KIND OF A COORD PROBLEM BETWEEN DEP CTLRS BECAUSE OF THE HDG WE WERE ASSIGNED. WE WERE ALSO GIVEN THE WRONG DEP FREQ FOR THE HDG WE WERE ASSIGNED. WHEN I REPORTED ON DEP AND CALLED WHAT I THOUGHT WAS THE ASSIGNED ALT, THE CTLR DID NOT IMMEDIATELY CORRECT US. SHE SEEMED TO BE MORE CONCERNED ABOUT TELLING US ABOUT THE TFC FIRST, THEN CORRECTING THE ALT. AT THE TIME OF OUR CHECK ON WITH DEP, IF THE CTLR HAD MADE THE CORRECTION, THERE WOULD NOT HAVE BEEN A PROBLEM. SUPPLEMENTAL INFORMATION FROM ACN 127760: F/O COPIED CLRNC. WROTE 4000 FOR ALT. SET ON ALERTER ON 4000. AFTER DEP, F/O ADVISED DEP CTL WE WERE IN RIGHT TURN CLIMBING TO (LEAVING 1300) 4000. DEP CTLR ACKNOWLEDGED, THEN ADVISED OF TFC AT 3000. CTLR ADVISED ASSIGNED ALT WAS 2000. TFC 1/2 MI AT 3000. INITIATED EVASIVE ACTION (DSCNT) TO 2000 (FROM 2700).
