Narrative:
I was working with a trainee when small transport X took off and turned to 360 degree climbing to 6000'. ARTS ii identification did not tag the aircraft. Small transport Y was handed off on a track wbound, descending to 5000', 10 mi nne of mry. Because traffic was heavy at the time, and aircraft call sign was not available on scope, efforts to determine same came too late, and loss of separation occurred between 5000' and 6000'. This was one of 3 aircraft that took off mry in a 10 minute period that did not 'tag up'.

Narrative: I WAS WORKING WITH A TRAINEE WHEN SMT X TOOK OFF AND TURNED TO 360 DEG CLIMBING TO 6000'. ARTS II ID DID NOT TAG THE ACFT. SMT Y WAS HANDED OFF ON A TRACK WBOUND, DESCENDING TO 5000', 10 MI NNE OF MRY. BECAUSE TFC WAS HEAVY AT THE TIME, AND ACFT CALL SIGN WAS NOT AVAILABLE ON SCOPE, EFFORTS TO DETERMINE SAME CAME TOO LATE, AND LOSS OF SEPARATION OCCURRED BETWEEN 5000' AND 6000'.
