Narrative:

Training at sector with moderate to heavy traffic, and lots of VFR's. 1 of 2 VHF frequencys had a stuck microphone. Normal errors the trnee made put the sector behind. The radar man (fpl) took over sector and started to square it away. I heard the radar man turn and descend 1 of the aircraft. I called another sector point him out. The other aircraft was being worked by another sector. Due to frequency congestion, I had approved the aircraft to enter our airspace, but did not take the handoff--so that aircraft was on other controller's frequency. He saw the problem and asked what to do, and was told other aircraft was descending. First aircraft did not turn or descend, and said he saw other aircraft and wanted to keep him in sight. The radar man waited too long to take sector over from trnee. I waited too long to shut aircraft off. Both of us were trying to provide maximum service to the aircraft and the trnee. In hindsight, approving aircraft to enter west/O talking to him is not good. I should have just told them to keep aircraft out. Stuck microphone really hurt radar side. More coordination was necessary because trnee hurt me on associate side. Also, poor quality of march line when I needed to coordinate.

Title: ACFT ENTERED ADJACENT AIRSPACE WITHOUT A RADAR HANDOFF AND RESULTED IN CONFLICTION WITH ANOTHER ACFT.

Narrative: TRNING AT SECTOR WITH MODERATE TO HEAVY TFC, AND LOTS OF VFR'S. 1 OF 2 VHF FREQS HAD A STUCK MIC. NORMAL ERRORS THE TRNEE MADE PUT THE SECTOR BEHIND. THE RADAR MAN (FPL) TOOK OVER SECTOR AND STARTED TO SQUARE IT AWAY. I HEARD THE RADAR MAN TURN AND DSND 1 OF THE ACFT. I CALLED ANOTHER SECTOR POINT HIM OUT. THE OTHER ACFT WAS BEING WORKED BY ANOTHER SECTOR. DUE TO FREQ CONGESTION, I HAD APPROVED THE ACFT TO ENTER OUR AIRSPACE, BUT DID NOT TAKE THE HDOF--SO THAT ACFT WAS ON OTHER CTLR'S FREQ. HE SAW THE PROB AND ASKED WHAT TO DO, AND WAS TOLD OTHER ACFT WAS DSNDING. FIRST ACFT DID NOT TURN OR DSND, AND SAID HE SAW OTHER ACFT AND WANTED TO KEEP HIM IN SIGHT. THE RADAR MAN WAITED TOO LONG TO TAKE SECTOR OVER FROM TRNEE. I WAITED TOO LONG TO SHUT ACFT OFF. BOTH OF US WERE TRYING TO PROVIDE MAX SVC TO THE ACFT AND THE TRNEE. IN HINDSIGHT, APPROVING ACFT TO ENTER W/O TALKING TO HIM IS NOT GOOD. I SHOULD HAVE JUST TOLD THEM TO KEEP ACFT OUT. STUCK MIC REALLY HURT RADAR SIDE. MORE COORD WAS NECESSARY BECAUSE TRNEE HURT ME ON ASSOCIATE SIDE. ALSO, POOR QUALITY OF MARCH LINE WHEN I NEEDED TO COORDINATE.
