SMA GIVEN STAGE II DEP; HAS CONFLICT WITH MLG DEPARTING JUST AFTER.

Narrative

I CONTACTED GRAND FORKS GND AND REQUESTED A STAGE II DEP TO THE SW. I WAS INSTRUCTED BY GND TO TAXI TO 17L; TURN R TO 200 DEG UPON REACHING 2100 FT; AND SQUAWK XXXX. TKOF WAS UNEVENTFUL AND TWR TOLD ME TO CONTACT DEP. I WAS AT APPROX 1700 FT MSL. DEP INSTRUCTED ME TO RESUME MY OWN NAV UPON REACHING 2300 FT. AFTER REACHING 2100 FT I TURNED R AGAIN TO A HDG OF 240 DEG TO INTERCEPT THE 219 DEG RADIAL TO JAMESTOWN; ND. WHILE CLBING ON A 240 DEG HDG FOR 4500 FT MSL; I WAS ADVISED BY DEP THAT I HAD TFC; AN MLG; AT MY 3 O'CLOCK POS. AT THE TIME I WAS ALERTED I SAW AT MY 3 O'CLOCK; OR SLIGHTLY AHEAD; AN MLG ALREADY AIRBORNE AFTER TAKING OFF OF 17R (PARALLEL RWY) AND CLBING IN MY DIRECTION AT AN ALARMING RATE. I RPTED SEEING THE TFC AND INITIALLY BEGAN A HARD R TURN BUT STOPPED BECAUSE MY TURN DID NOT APPEAR TO BE A GOOD IDEA; INSTEAD I CONTINUED CLBING STRAIGHT AHEAD; HOPING THE MLG WOULD BE ABLE TO OBSERVE ME. THE MLG PASSED DIRECTLY BELOW ME WITH APPROX 500 FT BTWN US. I BELIEVE THIS NEAR MISS OCCURRED BECAUSE OF POOR CTLR COORD OF ACFT.
