POSSIBLE UNAUTH UNCOORD PENETRATION OF THE NY ADIZ BY A C172 PLT WHEN HE IS UNABLE TO ESTABLISH 2-WAY COM WITH CTLR AT N90; NY.

Narrative

I FILED A VFR FLT PLAN FROM N07 TO 1N7. I CALLED NEW YORK APCH FOR A SQUAWK CODE TO DEPART N07; BECAUSE OF THE NEWLY IMPLEMENTED ADIZ. THEY GAVE ME A SQUAWK CODE AND CLRNC. AFTER DEPARTING N07; I TRIED TO CONTACT NEW YORK APCH TO LET THEM KNOW THAT I HAD TAKEN OFF FROM N07; AND WAS ENRTE TO 1N7; WHICH IS REQUIRED BY NEW PROCS ESTABLISHED FOR THE ARPT. THE FREQ WAS HEAVILY CONGESTED. I TRIED TO CALL NYC DEP MANY TIMES. THE XMISSIONS WERE GETTING STEPPED ON CONTINUOUSLY. I BELIEVE THEY RECEIVED MY XMISSION. I COULD NOT BE SURE. THE FLT IS A SHORT ONE TO 1N7. I CONTINUED THE FLT ON THE DIRECT HDG TO N07. I CONTINUED TO LEAVE THE SQUAWK CODE ON THE XPONDER; EVEN AFTER I WAS CLR OF THE ADIZ. I MAY HAVE GOTTEN MY INTENTIONS KNOWN TO THE APCH CTL. AFTER LNDG AT N07; I CALLED MILLVILLE FLT SVC AND CANCELLED THE FLT PLAN. THEN; I CALLED ZNY AND TOLD THEM I HAD A PROB CONTACTING THEM ON THAT FREQ; PROBABLY DUE TO OVERWHELMING CONGESTION. THEY SAID THAT IF I COULD NOT CONTACT THEM ON THE RETURN TRIP; THAT I SHOULD REMAIN CLR OF THE ADIZ UNTIL I WAS ABLE TO ESTABLISH 2-WAY COM WITH THEM. I FILED A FLT PLAN AND CALLED NY ON THE PHONE TO GET A SQUAWK CODE AND A CLRNC TO GET BACK INTO THE ADIZ. I TOOK OFF FROM N07 AND CLBED TO 3000 FT. THERE WERE PLTS TALKING TO ZNY. I COULD HEAR THEIR XMISSIONS TO EACH OTHER. I COULD NOT HEAR NY CTL. I DID NOT ENTER THE ADIZ. I DECIDED TO FLY TO SUSSEX ARPT WHERE I COULD GET MY RADIO CHKED OUT AT AN AVIONICS SHOP. I LANDED AT SUSSEX. I CALLED ON THE PHONE AND CLOSED MY FLT PLAN. THE AVIONICS REPAIRMAN TESTED MY RADIO AND SAID IT HAD A WEAK RECEIVER. I LEFT THE PLANE THERE SO THAT THE RADIO COULD BE REPAIRED. I GOT A RIDE FROM A FELLOW PLT TO TAKE ME BACK TO N07; WHERE MY PLANE IS BASED.
