Narrative:
Reported for duty and assigned to fxe pmp satellite sector. Very busy--8-10 practice approach aircraft continuously, then stuck microphone for 15 mins with 8 aircraft on vectors. No communication with any. All VFR and with no communication with approach. As soon as the stuck microphone was recognized, they all came back for 45 mins more of practice approachs. I left the position totally drained for 20 min break. Then assigned to fll north departure. Small aircraft X, in the air heading 320 degrees. Air carrier Y departed east and was turned to heading 340 degrees. Small aircraft X at 4000', air carrier Y at 5000'. Unrelated large transport nwbnd to 16000' reported no problem with WX. Small aircraft X at 3600' climbing requested higher for WX and was issued 10000'. Air carrier Y 10 mi east of small aircraft X requested heading 010 degrees for WX. Unable due to inbound traffic. My plane was to follow large transport path nwbnd and east of WX. I stopped departures off of fll and called for supervisor to discuss possible rerte due to WX out dta. 15 seconds later, air carrier Y requested a west turn for buildups. (I did not have the usual and required 3-DIMENSIONAL picture of the situation in my head.) air carrier Y issued heading 270 degrees at 5000', which put him on converging course with small aircraft X. My attention was still directed at gaining supervisor attention to discuss rertes. Supervisor came to my sector. As I was explaining WX situation, supervisor noticed conflict and pointed it out to me. Too late for evasive action. Issued climb to air carrier Y. Issued turn to small aircraft X. Small aircraft X (first to reply) was shaken. Air carrier Y was shaken and mad. I was scared. Actions: should not have climbed small aircraft X, should have climbed air carrier Y. Should not have turned air carrier Y for 'buildups.' factors: at the very least, there should have been a handoff position opened on fll north departure. That would have enabled me to concentrate on the primary job of separating aircraft instead of looking for help. Conclusion: more people to divide the workload would have probably prevented this error.

Title: SMA X HAD LESS THAN STANDARD SEPARATION FROM ACR Y. SYSTEM ERROR. NMAC.
Narrative: RPTED FOR DUTY AND ASSIGNED TO FXE PMP SATELLITE SECTOR. VERY BUSY--8-10 PRACTICE APCH ACFT CONTINUOUSLY, THEN STUCK MIC FOR 15 MINS WITH 8 ACFT ON VECTORS. NO COM WITH ANY. ALL VFR AND WITH NO COM WITH APCH. AS SOON AS THE STUCK MIC WAS RECOGNIZED, THEY ALL CAME BACK FOR 45 MINS MORE OF PRACTICE APCHS. I LEFT THE POS TOTALLY DRAINED FOR 20 MIN BREAK. THEN ASSIGNED TO FLL N DEP. SMA X, IN THE AIR HDG 320 DEGS. ACR Y DEPARTED E AND WAS TURNED TO HDG 340 DEGS. SMA X AT 4000', ACR Y AT 5000'. UNRELATED LGT NWBND TO 16000' RPTED NO PROB WITH WX. SMA X AT 3600' CLBING REQUESTED HIGHER FOR WX AND WAS ISSUED 10000'. ACR Y 10 MI E OF SMA X REQUESTED HDG 010 DEGS FOR WX. UNABLE DUE TO INBND TFC. MY PLANE WAS TO FOLLOW LGT PATH NWBND AND E OF WX. I STOPPED DEPS OFF OF FLL AND CALLED FOR SUPVR TO DISCUSS POSSIBLE RERTE DUE TO WX OUT DTA. 15 SECS LATER, ACR Y REQUESTED A W TURN FOR BUILDUPS. (I DID NOT HAVE THE USUAL AND REQUIRED 3-DIMENSIONAL PICTURE OF THE SIT IN MY HEAD.) ACR Y ISSUED HDG 270 DEGS AT 5000', WHICH PUT HIM ON CONVERGING COURSE WITH SMA X. MY ATTN WAS STILL DIRECTED AT GAINING SUPVR ATTN TO DISCUSS RERTES. SUPVR CAME TO MY SECTOR. AS I WAS EXPLAINING WX SIT, SUPVR NOTICED CONFLICT AND POINTED IT OUT TO ME. TOO LATE FOR EVASIVE ACTION. ISSUED CLB TO ACR Y. ISSUED TURN TO SMA X. SMA X (FIRST TO REPLY) WAS SHAKEN. ACR Y WAS SHAKEN AND MAD. I WAS SCARED. ACTIONS: SHOULD NOT HAVE CLBED SMA X, SHOULD HAVE CLBED ACR Y. SHOULD NOT HAVE TURNED ACR Y FOR 'BUILDUPS.' FACTORS: AT THE VERY LEAST, THERE SHOULD HAVE BEEN A HDOF POS OPENED ON FLL N DEP. THAT WOULD HAVE ENABLED ME TO CONCENTRATE ON THE PRIMARY JOB OF SEPARATING ACFT INSTEAD OF LOOKING FOR HELP. CONCLUSION: MORE PEOPLE TO DIVIDE THE WORKLOAD WOULD HAVE PROBABLY PREVENTED THIS ERROR.
