Narrative:
On departure from bei (first leg, first pairing), we took off from runway 15R on the paleo 3 departure. Departure frequency was very busy and wre were given a heading of 090 degrees. A short time later, we were chastised for not intercepting the bwi 133 degree radial on the paleo 3 as instructed. My first officer replied that her transmission may have been clipped because all we copied was a heading of 090 degrees (I was flying). We were then given another heading to intercept the 133 degree radial. Unfortunately, that heading intercepted the 133 degree radial after the sie intercepting radial. As I was correcting back, once again departure queried us and told us to correct and fly the paleo 3 departure. They were not pleased. We initially simply did not understand the clearance as it was intended. Subsequently, we simply made an error in correcting back to the departure as depicted. On a -700, there were numerous cues to keep us from overshooting the sie radial. I think we talked about and focused on the initial communication problem. We should have put that behind us and focused instead on the task at hand. Fly first and foremost and back the other guy up.

Title: B737-700 CREW HAD A CLRNC READBACK HEARBACK PROB THAT RESULTED IN A TRACK DEV DEPARTING BWI.
Narrative: ON DEP FROM BEI (FIRST LEG, FIRST PAIRING), WE TOOK OFF FROM RWY 15R ON THE PALEO 3 DEP. DEP FREQ WAS VERY BUSY AND WRE WERE GIVEN A HDG OF 090 DEGS. A SHORT TIME LATER, WE WERE CHASTISED FOR NOT INTERCEPTING THE BWI 133 DEG RADIAL ON THE PALEO 3 AS INSTRUCTED. MY FO REPLIED THAT HER XMISSION MAY HAVE BEEN CLIPPED BECAUSE ALL WE COPIED WAS A HDG OF 090 DEGS (I WAS FLYING). WE WERE THEN GIVEN ANOTHER HDG TO INTERCEPT THE 133 DEG RADIAL. UNFORTUNATELY, THAT HDG INTERCEPTED THE 133 DEG RADIAL AFTER THE SIE INTERCEPTING RADIAL. AS I WAS CORRECTING BACK, ONCE AGAIN DEP QUERIED US AND TOLD US TO CORRECT AND FLY THE PALEO 3 DEP. THEY WERE NOT PLEASED. WE INITIALLY SIMPLY DID NOT UNDERSTAND THE CLRNC AS IT WAS INTENDED. SUBSEQUENTLY, WE SIMPLY MADE AN ERROR IN CORRECTING BACK TO THE DEP AS DEPICTED. ON A -700, THERE WERE NUMEROUS CUES TO KEEP US FROM OVERSHOOTING THE SIE RADIAL. I THINK WE TALKED ABOUT AND FOCUSED ON THE INITIAL COM PROB. WE SHOULD HAVE PUT THAT BEHIND US AND FOCUSED INSTEAD ON THE TASK AT HAND. FLY FIRST AND FOREMOST AND BACK THE OTHER GUY UP.
