Potential conflict with corporate turboprop as lear jet performs a heading track position deviation during radar vectoring from las. The lear jet, aircraft Y, was told runway heading and instead took up radial intercept heading as per SID aeronautical chart.

Narrative:
We had departed las to the south and were given a 210 degree heading, climb and maintain 7000 ft, which we complied with. A lear departed behind us. His clearance was to fly runway heading, climb and maintain 7000 ft, which he acknowledged. What he did was turn right and join the las 211 degree radial, climbing to 7000 ft, which is part of the oasys SID. That put him into direct conflict with our flight. We saw the lear pass off our left wing at 7000 ft about 1 mi away, a few hundred ft before we leveled at 7000 ft. 2 contributing factors on his part were: 1) not having the transponder on until after reaching 7000 ft. 2) the lear was late in switching from local control to departure. On our end, we initially came up on the wrong departure frequency.

Title: POTENTIAL CONFLICT WITH CORPORATE TURBOPROP AS LEAR JET PERFORMS A HDG TRACK POS DEV DURING RADAR VECTORING FROM LAS. THE LEAR JET, ACFT Y, WAS TOLD RWY HDG AND INSTEAD TOOK UP RADIAL INTERCEPT HDG AS PER SID AERO CHART.
Narrative: WE HAD DEPARTED LAS TO THE S AND WERE GIVEN A 210 DEG HDG, CLB AND MAINTAIN 7000 FT, WHICH WE COMPLIED WITH. A LEAR DEPARTED BEHIND US. HIS CLRNC WAS TO FLY RWY HDG, CLB AND MAINTAIN 7000 FT, WHICH HE ACKNOWLEDGED. WHAT HE DID WAS TURN R AND JOIN THE LAS 211 DEG RADIAL, CLBING TO 7000 FT, WHICH IS PART OF THE OASYS SID. THAT PUT HIM INTO DIRECT CONFLICT WITH OUR FLT. WE SAW THE LEAR PASS OFF OUR L WING AT 7000 FT ABOUT 1 MI AWAY, A FEW HUNDRED FT BEFORE WE LEVELED AT 7000 FT. 2 CONTRIBUTING FACTORS ON HIS PART WERE: 1) NOT HAVING THE XPONDER ON UNTIL AFTER REACHING 7000 FT. 2) THE LEAR WAS LATE IN SWITCHING FROM LCL CTL TO DEP. ON OUR END, WE INITIALLY CAME UP ON THE WRONG DEP FREQ.
