Narrative:
We were cleared for takeoff runway 30 at iad. After departure, we were assigned a heading of 305 degrees which I read back to ATC (iad tower/ground) as I set in the heading bug. Shortly after we were switched to departure, I checked in with departure. A short time after that, we received an RA alert. It was VFR and we both saw the traffic and reported that to departure. Departure asked our heading and I replied 305 degrees. They said 'you were assigned 350 degrees, now fly heading 020 degrees.' I set the heading bug and read back 020 degrees. At heading 020 degrees the captain (PF) asked to verify assigned heading. Departure said 350 degrees, which we then set in and read back. Then there was some confusion with our call sign for a number of xmissions. We proceeded on course without any further incident.

Title: LJ60 CREW HAD CONFUSING HDGS ASSIGNED AFTER TKOF.
Narrative: WE WERE CLRED FOR TKOF RWY 30 AT IAD. AFTER DEP, WE WERE ASSIGNED A HDG OF 305 DEGS WHICH I READ BACK TO ATC (IAD TWR/GND) AS I SET IN THE HDG BUG. SHORTLY AFTER WE WERE SWITCHED TO DEP, I CHKED IN WITH DEP. A SHORT TIME AFTER THAT, WE RECEIVED AN RA ALERT. IT WAS VFR AND WE BOTH SAW THE TFC AND RPTED THAT TO DEP. DEP ASKED OUR HDG AND I REPLIED 305 DEGS. THEY SAID 'YOU WERE ASSIGNED 350 DEGS, NOW FLY HDG 020 DEGS.' I SET THE HDG BUG AND READ BACK 020 DEGS. AT HDG 020 DEGS THE CAPT (PF) ASKED TO VERIFY ASSIGNED HDG. DEP SAID 350 DEGS, WHICH WE THEN SET IN AND READ BACK. THEN THERE WAS SOME CONFUSION WITH OUR CALL SIGN FOR A NUMBER OF XMISSIONS. WE PROCEEDED ON COURSE WITHOUT ANY FURTHER INCIDENT.
