COMANCHE PLT ALLEGED TO HAVE CROSSED ADIZ ON VFR FLT.

Narrative

A FLEW A COMANCHE 400 FROM DALLAS; TX; TO MIAMI; FL; WITH A FUEL STOP IN PENSACOLA; FL. I WAS NOT ON A FLT PLAN; FLYING VFR; VMC; AND WITH AN INOP XPONDER. I DID NOT KNOW ABOUT THE XPONDER UNTIL JUST BEFORE LEAVING; OR THAT THERE WAS A PROB ALSO WITH THE LORAN THAT I DID NOT DISCOVER UNTIL INFLT. I TOOK OFF FROM PENSACOLA AND FLEW E ALONG THE COAST AT 1500 FT MSL. I CONTACTED APPLICABLE APCH CTLS ENRTE: PENSACOLA; HURLBERT; TYNDALL AFB. I REQUESTED TO KNOW THE 'HOT' WHISKEY AREAS; AND WAS ADVISED BY TYNDALL THAT W151 WAS THE ONLY ONE THAT WAS HOT. WHEN I WAS WELL E OF W151; I TURNED SLIGHTLY TO THE SE. AT THIS TIME I WAS USING GND REFS. I NOW ALSO STARTED TO USE LORAN FOR HDGS BUT BELIEVE THAT THIS IS WHERE THE ERRONEOUS INFO BEGAN. AS I TURNED TO THE SE; I HAD VISUAL CONTACT WITH THE LIGHTS FROM WEST FLORIDA AND USED LORAN TO NAV TO ST PETERSBURG. I ALSO HAD TO CLB TO MAINTAIN GND CONTACT; I CLBED TO 7500 FT MSL. I THEN PROCEEDED JUST W OF THE FLORIDA COAST TO N OF SARASOTA AND PROCEEDED E WITH EVENTUAL LNDG AT TAMIAMI ARPT. UPON LNDG AND GOING TO THE FBO; I RECEIVED A CALL FROM OAK GROVE (GCI AT TYNDALL AFB) THEY SAID THAT THEY TRACKED A TARGET; TO WITHIN 5 MINS OF MY LNDG; TO THE VICINITY OF TAMIAMI; THAT HAD GONE INSIDE THE ADIZ OFF THE FLORIDA COAST; AND WANTED TO KNOW MY NAME; TAIL NUMBER; ETC. MY LORAN HAD BEEN GIVING ERRONEOUS INFO; AND WAS OFF BY ABOUT 50 MI BY THE TIME THAT I HAD LANDED. HOWEVER; I BELIEVE THAT I WAS NAVING VISUALLY CLOSE ENOUGH TO THE COAST TO AVOID THE ADIZ. ALSO; I HAD BEEN IN CONTACT WITH TYNDALL APCH; WHICH IS WHERE OAK GROVE IS LOCATED; SO I WOULD THINK THAT I WOULD NOT BE TECHNICALLY AN UNKNOWN IF I DID CROSS THE ADIZ. I WAS ALSO MONITORING 121.0 AND DID NOT HEAR AN 'UNK RIDER' CALL; WHICH I HAVE HEARD BROADCAST BEFORE BY GCI TO OTHER UNK TFC.
