C152 PLT HAS NMAC DURING DEP.

Narrative

THE WIND WAS FROM THE S AT 3-5 KTS. SEVERAL ACFT HAD DEPARTED ON RWY 20 PRIOR TO THE TIME I STARTED MY ACFT. I ANNOUNCED BACK TAXI FOR RWY 20 ON THE CTAF. WHILE DOING MY RUN-UP; A BARON CALLED 7 MI OUT FOR RWY 2. THE ARPT MGR REPLIED WITH WINDS; ALTIMETER; AND ADVISED THE BARON PLT THAT ACFT WERE USING RWY 20. THE BARON PLT ACKNOWLEDGED. I FINISHED MY RUN-UP AND SCANNED THE APCHS FOR BOTH RWYS (2 AND 20) LOOKING FOR TFC. NO TFC WAS OBSERVED. THE BARON PLT RPTED DOWNWIND TO BASE FOR RWY 20. I DID NOT SEE THE BARON; BUT THIS IS NOT UNUSUAL SINCE TWINS AND JETS OFTEN FLY WIDE PATTERNS AND ARE NOT ALWAYS VISIBLE FROM THE END OF THE RWY DUE TO TREES. BASED ON THE BARON PLT'S RPT AND NOT SEEING ANY ACFT; I ANNOUNCED DEPARTING RWY 20. WHILE CLBING OUT; I HEARD THE BARON MAKE ANOTHER ANNOUNCEMENT. HIS ANNOUNCEMENT WAS SOMEWHAT CONFUSING AND I DO NOT RECALL THE DETAILS. ABOUT THAT TIME; I LOOKED BELOW AND TO THE R OF MY ACFT AND SAW THE BARON PASS BENEATH ME ON FINAL APCH FOR RWY 2. (I WAS FLYING R SEAT. IF I HAD BEEN IN THE L SEAT I NEVER WOULD HAVE SEEN THE BARON.) I WAS ABOUT 800 FT AGL AND ESTIMATE THE BARON WAS ABOUT 400 FT AGL. I WAS DISTURBED BY THE SIT AND MADE SEVERAL COMMENTS TO THE BARON PLT OVER THE CTAF EXPRESSING MY DISPLEASURE WITH HIS TFC PATTERN/POS RPTS. I REALLY HOPE THAT THIS INDIVIDUAL SAW ME AND WAS AWARE OF MY FLT PATH BECAUSE I HAD NO CLUE WHERE HE WAS UNTIL HE PASSED BELOW ME DUE TO THE INACCURACY OF HIS POS RPTS.
