POTENTIAL CONFLICT BTWN SMA AND DEP ACR WDB.

Narrative

THE FLT WOULD TAKE ABOUT 30 MINS AND WOULD TAKE ME THROUGH THE MIAMI TCA. I KNEW I NEEDED TO CONTACT MIAMI CTR AS SOON AS POSSIBLE AFTER DEP AND ON CLBING BEGAN TRYING TO CONTACT THEM. AS I ESTABLISHED CONTACT THE CTLR NOW SAID TO 'REMAIN CLR OF THE TCA;' AT THAT TIME I TURNED TO A HDG OF 320 FROM AN ON COURSE HDG OF 30 DEGS AND HEADED AWAY FROM THE TCA AT 1800 FT. APPROX 1 MIN LATER I WAS TOLD; 'TURN TO 320 AND REMAIN AT 2000 FT. SINCE I WAS ALREADY GOING 320 DEGS I QUICKLY LOOKED AT THE HDG NECESSARY TO GO TO FXE AND IT WAS 32 DEGS ON THE LORAN DISPLAY AND SO I TURNED TO 32 DEGS TO AN ON COURSE HDG. AS I WAS ON THIS COURSE FOR 2 TO 3 MINS I WAS AGAIN CONTACTED BY ATC AND WAS ASKED IF I WAS HDG 320; AND I ANSWERED AFFIRMATIVE. APPROX 1 MIN LATER I WAS CONTACTED BY ATC; 'TURN L TO 270 IMMEDIATELY; TFC PROX ALERT!' I COMPLIED AND TURNED L IMMEDIATELY TO 270 DEGS AND I SAW A JETLINER (POSSIBLY) TO MY SE WHO WAS TURNING TO HIS R AND APPEARED TO BE IN A SHALLOW CLB. THIS TFC WAS 1.5 TO 2 MI AWAY AT THIS TIME AND I WAS AT 2000 FT. MY LACK OF RECENCY OF EXPERIENCE WAS PROBABLY A CONTRIBUTING FACTOR. I SHOULD HAVE ASKED IF I WAS CLRED TO ENTER THE TCA. I SHOULD HAVE ASKED IF MY IFR FLT PLAN WAS OPENED. THIS PERCEPTION OF BEING IN THE CTLR'S AIRSPACE AND GETTING RADAR VECTORS TO MY DEST WAS APPARENTLY INCORRECT. I BELIEVE INADEQUATE COM CAUSED THE PROBLEM. THE ACTUAL CONFUSION OF MY DECISION TO GO 32 DEGS INSTEAD OF 320 WAS A HUMAN ERROR DUE TO LACK OF RECENCY OF EXPERIENCE AND IT DID NOT CLICK THAT 32.0 WAS NOT 320.
