Narrative:
On climb out from dfw on the dalles 5 we were given pilot's discretion to climb to 17000 ft. We chose to level off at the altitude when we were given the pilot's discretion at 6500 ft. Our horizontal assignment was a heading to intercept the 084 degree radial off TTT. We were staying low because of turbulent air and thunderstorm overhang above us. Clear further east. At the time we heard a re-clearance to climb to 10000 ft then pilot's discretion to 17000 ft, I thought I heard pick up heading 040 degrees. We tried to clarify but we were avoiding thunderstorms and couldn't get back to ATC. We were on the 084 degree radial and I noticed on TCASII an aircraft at about 6000 ft about 3-5 NM just right of us. This was the time ATC came back to tell us we were cleared back to the 084 degree radial. We were climbing at this time and I saw the aircraft. By the time we passed we were at least 1500 ft above. We told ATC we were on the 084 degree radial and he said there was no problem with separation. Apparently we missed the 040 degree assignment.

Title: A FLC WAS DETOURING TSTMS WHEN ARTCC ADVISED THEM OF TFC IN THE AREA AND TO PROCEED ON THE ORIGINAL COURSE.
Narrative: ON CLBOUT FROM DFW ON THE DALLES 5 WE WERE GIVEN PLT'S DISCRETION TO CLB TO 17000 FT. WE CHOSE TO LEVEL OFF AT THE ALT WHEN WE WERE GIVEN THE PLT'S DISCRETION AT 6500 FT. OUR HORIZ ASSIGNMENT WAS A HEADING TO INTERCEPT THE 084 DEG RADIAL OFF TTT. WE WERE STAYING LOW BECAUSE OF TURBULENT AIR AND TSTM OVERHANG ABOVE US. CLR FURTHER E. AT THE TIME WE HEARD A RE-CLRNC TO CLB TO 10000 FT THEN PLT'S DISCRETION TO 17000 FT, I THOUGHT I HEARD PICK UP HDG 040 DEGS. WE TRIED TO CLARIFY BUT WE WERE AVOIDING TSTMS AND COULDN'T GET BACK TO ATC. WE WERE ON THE 084 DEG RADIAL AND I NOTICED ON TCASII AN ACFT AT ABOUT 6000 FT ABOUT 3-5 NM JUST R OF US. THIS WAS THE TIME ATC CAME BACK TO TELL US WE WERE CLRED BACK TO THE 084 DEG RADIAL. WE WERE CLBING AT THIS TIME AND I SAW THE ACFT. BY THE TIME WE PASSED WE WERE AT LEAST 1500 FT ABOVE. WE TOLD ATC WE WERE ON THE 084 DEG RADIAL AND HE SAID THERE WAS NO PROB WITH SEPARATION. APPARENTLY WE MISSED THE 040 DEG ASSIGNMENT.
