Narrative:

I departed W29 with ADIZ clearance, for esn to practice takeoffs, lndgs and other airwork. I had filed a flight plan to re-enter the ADIZ. I called potomac TRACON for clearance to enter. They gave me a squawk and cleared me to enter the ADIZ for landing at W29. Shortly thereafter ATC queried whether I had the field in sight and I confirmed that I did. They told me that radar coverage was terminated and that I should contact W29 for advisories. I then switched to unicom, changed the squawk to 1200, entered the pattern and landed. Upon landing, the W29 FBO told me to contact ATC which I did. I explained what happened and they advised me that I should have carried the squawk to the ground.

THEY GAVE ME A SQUAWK AND CLRED ME TO ENTER THE ADIZ FOR LNDG AT W29. SHORTLY THEREAFTER ATC QUERIED WHETHER I HAD THE FIELD IN SIGHT AND I CONFIRMED THAT I DID. THEY TOLD ME THAT RADAR COVERAGE WAS TERMINATED AND THAT I SHOULD CONTACT W29 FOR ADVISORIES. I THEN SWITCHED TO UNICOM, CHANGED THE SQUAWK TO 1200, ENTERED THE PATTERN AND LANDED.
