Narrative:
On apr/tue/03, departed cyx approximately XA40 for practice approachs at thv and dmw VOR runway 34 via EMI. Completed NDB and missed approach at thv. Hbg approach advised I contact potomac approach for the sbound leg on frequency 125.52. I did, and was assigned code (if memory serves). Upon approaching proximity of EMI (about 5 NM north), I was instructed to maintain 4300 ft until established, 'cleared for the approach, frequency change approved, squawk 1200.' I was dissatisfied with my inbound course entry which is published as 358 degrees, so I did a course reversal to try again. The 178 degree leg was extended approximately 8 NM south of EMI to give plenty of time to set up inbound. I remained at 3000 ft, crossed the VOR, and completed the approach to a circle-to-land runway 16. Then I was called on unicom to land and call a phone number. They had me call potomac TRACON. Mr X informed me I had entered the washington ADIZ. After the call, I could see that I had penetrated the veil (though below class B floor altitude.) upon reflection, it is my belief that the controller who told me to switch from the discrete code to 1200 before I was established inbound was a contributing factor to the alleged infraction.

Title: PA28 PLT WAS DUMPED TO A VFR XPONDER CODE WHEN FLYING TO AN ARPT ON THE EDGE OF DC ADIZ AIRSPACE.
Narrative: ON APR/TUE/03, DEPARTED CYX APPROX XA40 FOR PRACTICE APCHS AT THV AND DMW VOR RWY 34 VIA EMI. COMPLETED NDB AND MISSED APCH AT THV. HBG APCH ADVISED I CONTACT POTOMAC APCH FOR THE SBOUND LEG ON FREQ 125.52. I DID, AND WAS ASSIGNED CODE (IF MEMORY SERVES). UPON APCHING PROX OF EMI (ABOUT 5 NM N), I WAS INSTRUCTED TO MAINTAIN 4300 FT UNTIL ESTABLISHED, 'CLRED FOR THE APCH, FREQ CHANGE APPROVED, SQUAWK 1200.' I WAS DISSATISFIED WITH MY INBOUND COURSE ENTRY WHICH IS PUBLISHED AS 358 DEGS, SO I DID A COURSE REVERSAL TO TRY AGAIN. THE 178 DEG LEG WAS EXTENDED APPROX 8 NM S OF EMI TO GIVE PLENTY OF TIME TO SET UP INBOUND. I REMAINED AT 3000 FT, CROSSED THE VOR, AND COMPLETED THE APCH TO A CIRCLE-TO-LAND RWY 16. THEN I WAS CALLED ON UNICOM TO LAND AND CALL A PHONE NUMBER. THEY HAD ME CALL POTOMAC TRACON. MR X INFORMED ME I HAD ENTERED THE WASHINGTON ADIZ. AFTER THE CALL, I COULD SEE THAT I HAD PENETRATED THE VEIL (THOUGH BELOW CLASS B FLOOR ALT.) UPON REFLECTION, IT IS MY BELIEF THAT THE CTLR WHO TOLD ME TO SWITCH FROM THE DISCRETE CODE TO 1200 BEFORE I WAS ESTABLISHED INBOUND WAS A CONTRIBUTING FACTOR TO THE ALLEGED INFRACTION.
