Narrative:

MD80 was climbing nebound. DA20 was on a vector of 210 degrees. DA20 was descending at what appeared to be a good rate. Got to working a couple of VFR's that didn't answer and had to make multiple xmissions. Looked back at DA20 and MD80. DA20's descent slowed and a conflict was developing. I turned the MD80 to a 40 degree heading and the DA20 to a 180 degree heading. Appeared to have barely kept 3 mi. Contributing factors: multiple targets unidented popped off a satellite uncontrolled field requiring traffic calls to aircraft that didn't answer.

Narrative: MD80 WAS CLBING NEBOUND. DA20 WAS ON A VECTOR OF 210 DEGS. DA20 WAS DSNDING AT WHAT APPEARED TO BE A GOOD RATE. GOT TO WORKING A COUPLE OF VFR'S THAT DIDN'T ANSWER AND HAD TO MAKE MULTIPLE XMISSIONS. LOOKED BACK AT DA20 AND MD80. DA20'S DSCNT SLOWED AND A CONFLICT WAS DEVELOPING. I TURNED THE MD80 TO A 40 DEG HDG AND THE DA20 TO A 180 DEG HDG. APPEARED TO HAVE BARELY KEPT 3 MI. CONTRIBUTING FACTORS: MULTIPLE TARGETS UNIDENTED POPPED OFF A SATELLITE UNCTLED FIELD REQUIRING TFC CALLS TO ACFT THAT DIDN'T ANSWER.
