Narrative:

#1 heading 070 degrees, I think just outside class C airspace at bdl on 125.8 approach/departure. I don't know if there was a conflict alert, but controller called 'converging traffic at 9 O'clock position' -- something in his voice! Quick glance over shoulder full back and left on yoke recovered at 3800 ft. Approximately 3 seconds later, plane #2 below and ahead on course 020 degrees (approximately). At the same time ATC directed frequency change to 123.95. I also informed ATC controller of near midair collision. At that time, he told me that they were not in contact with that plane. From reading I know that I was close to the most likely position to have this happen -- VMC, good visibility, 10 NM to busy airport! Usually radar advisories give much more warning, but many times I have visual before the call. I don't know where #2 came from. I would expect to have seen off my right wing. At the time the sun was off the right wing. I don't think #2 came up from below, closure rate was much too great. The real mushroom effect. I was lit up -- strobes, beacon, and recognition lights. Thanks to the controller I'm here. I'm sorry to say that I don't think I would have spotted #2 on my own in time. I also do not believe that #2 would have spotted me. I must have been big as a house in front of him when I took action. I estimate 1-2 seconds from collision. I only wish the 'other guy' had a clue how close it was. I don't believe 'he' does. My guess is the autoplt was flying and pilot was 'inside the cockpit.'

Narrative: #1 HDG 070 DEGS, I THINK JUST OUTSIDE CLASS C AIRSPACE AT BDL ON 125.8 APCH/DEP. I DON'T KNOW IF THERE WAS A CONFLICT ALERT, BUT CTLR CALLED 'CONVERGING TFC AT 9 O'CLOCK POS' -- SOMETHING IN HIS VOICE! QUICK GLANCE OVER SHOULDER FULL BACK AND L ON YOKE RECOVERED AT 3800 FT. APPROX 3 SECONDS LATER, PLANE #2 BELOW AND AHEAD ON COURSE 020 DEGS (APPROX). AT THE SAME TIME ATC DIRECTED FREQUENCY CHANGE TO 123.95. I ALSO INFORMED ATC CTLR OF NMAC. AT THAT TIME, HE TOLD ME THAT THEY WERE NOT IN CONTACT WITH THAT PLANE. FROM READING I KNOW THAT I WAS CLOSE TO THE MOST LIKELY POS TO HAVE THIS HAPPEN -- VMC, GOOD VISIBILITY, 10 NM TO BUSY ARPT! USUALLY RADAR ADVISORIES GIVE MUCH MORE WARNING, BUT MANY TIMES I HAVE VISUAL BEFORE THE CALL. I DON'T KNOW WHERE #2 CAME FROM. I WOULD EXPECT TO HAVE SEEN OFF MY R WING. AT THE TIME THE SUN WAS OFF THE R WING. I DON'T THINK #2 CAME UP FROM BELOW, CLOSURE RATE WAS MUCH TOO GREAT. THE REAL MUSHROOM EFFECT. I WAS LIT UP -- STROBES, BEACON, AND RECOGNITION LIGHTS. THANKS TO THE CTLR I'M HERE. I'M SORRY TO SAY THAT I DON'T THINK I WOULD HAVE SPOTTED #2 ON MY OWN IN TIME. I ALSO DO NOT BELIEVE THAT #2 WOULD HAVE SPOTTED ME. I MUST HAVE BEEN BIG AS A HOUSE IN FRONT OF HIM WHEN I TOOK ACTION. I ESTIMATE 1-2 SECONDS FROM COLLISION. I ONLY WISH THE 'OTHER GUY' HAD A CLUE HOW CLOSE IT WAS. I DON'T BELIEVE 'HE' DOES. MY GUESS IS THE AUTOPLT WAS FLYING AND PLT WAS 'INSIDE THE COCKPIT.'
