The pilot of the aircraft on my frequency for VFR advisories reported an near midair collision with opposite direction traffic. Callback conversation with reporter revealed following information. The pilot that reported the near midair collision had been on reporter's frequency about 5 minutes before the reported near midair collision occurred. When the aircraft first called reporter, a squawk was given and radar contact was called. Shortly after that, reporter gave a traffic advisory to the pilot with no response from the pilot. Again, the controller called the pilot with a traffic advisory with no response. Repeated calls to the aircraft were fruitless. Some 5 minutes after the last call from the reporter, the pilot of the small aircraft reported that he had just taken evasive action to avoid a collision with an unknown small aircraft. At the time, the aircraft was flying through a very congested VFR practice area north of fort lauderdale over the everglades. Reporter said that he did not see the specific target nor was he inclined to give a traffic advisory because he assumed that he no longer had radio contact with subject aircraft.

Title: SMA HAD NEAR COLLISION WITH SMA WHILE TRANSITING A VFR PRACTICE AREA.
Narrative: THE PLT OF THE ACFT ON MY FREQ FOR VFR ADVISORIES RPTED AN NMAC WITH OPPOSITE DIRECTION TFC. CALLBACK CONVERSATION WITH RPTR REVEALED FOLLOWING INFO. THE PLT THAT RPTED THE NMAC HAD BEEN ON RPTR'S FREQ ABOUT 5 MINUTES BEFORE THE RPTED NMAC OCCURRED. WHEN THE ACFT FIRST CALLED RPTR, A SQUAWK WAS GIVEN AND RADAR CONTACT WAS CALLED. SHORTLY AFTER THAT, RPTR GAVE A TFC ADVISORY TO THE PLT WITH NO RESPONSE FROM THE PLT. AGAIN, THE CTLR CALLED THE PLT WITH A TFC ADVISORY WITH NO RESPONSE. REPEATED CALLS TO THE ACFT WERE FRUITLESS. SOME 5 MINUTES AFTER THE LAST CALL FROM THE RPTR, THE PLT OF THE SMA RPTED THAT HE HAD JUST TAKEN EVASIVE ACTION TO AVOID A COLLISION WITH AN UNKNOWN SMA. AT THE TIME, THE ACFT WAS FLYING THROUGH A VERY CONGESTED VFR PRACTICE AREA N OF FORT LAUDERDALE OVER THE EVERGLADES. RPTR SAID THAT HE DID NOT SEE THE SPECIFIC TARGET NOR WAS HE INCLINED TO GIVE A TFC ADVISORY BECAUSE HE ASSUMED THAT HE NO LONGER HAD RADIO CONTACT WITH SUBJECT ACFT.
