Narrative:

I was returning south down the farmington river valley at 1800 ft (below bdl class 'C' airspace), 8.5 mi west of bdl, by DME, GPS. I watched a cessna 310 approach my port-rear quarter. They came from bdl controled space at 90 degrees, then flew adjacent in formation, getting closer and closer obviously looking me over. Finally, I dove down to avoid a collision. I felt bdl vectored this plane to me as it approached from their area, then returned. Additionally, when I landed at hartford, the tower operator informed me that bradley has tracked me from northwest and I was flying 'erratically.' since I had a tv camera man as a witness, I voluntarily called bdl tower and explained that I flew straight up the farmington valley, made 1 circle 18 mi northwest of bdl, then straight south back to hfd. The nearest I was to bdl was 8.5 mi but was below their airspace. When they heard I had a witness they denied any knowledge of problem! The next day I had my altitude encoding system recertified. It not only passed requirements, but the avionics shop stated it was fine before recertification. I feel, because I was near but below bdl airspace, they requested the cessna 310 to check me out. Because my aircraft has small numbers the overzealous 310 pilot flew too close to me. When confronted, bdl denied any problem when I told them I had a viable witness.

Title: PLT OF AN SMA SEL COMPLAINED THAT ANOTHER ACFT CAME UP ALONGSIDE TOO CLOSE IN OBSERVING HIS ACFT IDENT N NUMBER.

Narrative: I WAS RETURNING S DOWN THE FARMINGTON RIVER VALLEY AT 1800 FT (BELOW BDL CLASS 'C' AIRSPACE), 8.5 MI W OF BDL, BY DME, GPS. I WATCHED A CESSNA 310 APCH MY PORT-REAR QUARTER. THEY CAME FROM BDL CTLED SPACE AT 90 DEGS, THEN FLEW ADJACENT IN FORMATION, GETTING CLOSER AND CLOSER OBVIOUSLY LOOKING ME OVER. FINALLY, I DOVE DOWN TO AVOID A COLLISION. I FELT BDL VECTORED THIS PLANE TO ME AS IT APCHED FROM THEIR AREA, THEN RETURNED. ADDITIONALLY, WHEN I LANDED AT HARTFORD, THE TWR OPERATOR INFORMED ME THAT BRADLEY HAS TRACKED ME FROM NW AND I WAS FLYING 'ERRATICALLY.' SINCE I HAD A TV CAMERA MAN AS A WITNESS, I VOLUNTARILY CALLED BDL TWR AND EXPLAINED THAT I FLEW STRAIGHT UP THE FARMINGTON VALLEY, MADE 1 CIRCLE 18 MI NW OF BDL, THEN STRAIGHT S BACK TO HFD. THE NEAREST I WAS TO BDL WAS 8.5 MI BUT WAS BELOW THEIR AIRSPACE. WHEN THEY HEARD I HAD A WITNESS THEY DENIED ANY KNOWLEDGE OF PROB! THE NEXT DAY I HAD MY ALT ENCODING SYS RECERTIFIED. IT NOT ONLY PASSED REQUIREMENTS, BUT THE AVIONICS SHOP STATED IT WAS FINE BEFORE RECERTIFICATION. I FEEL, BECAUSE I WAS NEAR BUT BELOW BDL AIRSPACE, THEY REQUESTED THE CESSNA 310 TO CHK ME OUT. BECAUSE MY ACFT HAS SMALL NUMBERS THE OVERZEALOUS 310 PLT FLEW TOO CLOSE TO ME. WHEN CONFRONTED, BDL DENIED ANY PROB WHEN I TOLD THEM I HAD A VIABLE WITNESS.
