Narrative:
I had filed an ADIZ flight plan with the flight service station, and prior to taking off from tipton airport (fort meade), contacted the potomac TRACON for a discrete ADIZ squawk code. I put in the squawk code, and took off from tipton, after listening to local advisories. On climb out, I realized that while I could hear various communications from the approach facilities, I could not talk to them. Since radio contact is essential for operating in the ADIZ, I elected to land immediately. During the landing phase, the transponder was still set to a discrete ADIZ code, and not 7600. Thus, in my opinion, during the landing phase, potomac TRACON may have thought that I was not in compliance with the ADIZ procedures. While no contacts were made on their behalf, I feel as though in the event like this taking place again, it would be more appropriate to have code 7600 in the transponder.

Title: C172 CFI KEPT HIS XPONDER CODE ON PCT'S ASSIGNED SQUAWK CODE, RETURNS AND LANDS, WHEN HIS VHF RECEIVER IS MALFUNCTIONING AFTER DEP FROM FME, MD.
Narrative: I HAD FILED AN ADIZ FLT PLAN WITH THE FLT SVC STATION, AND PRIOR TO TAKING OFF FROM TIPTON ARPT (FORT MEADE), CONTACTED THE POTOMAC TRACON FOR A DISCRETE ADIZ SQUAWK CODE. I PUT IN THE SQUAWK CODE, AND TOOK OFF FROM TIPTON, AFTER LISTENING TO LCL ADVISORIES. ON CLBOUT, I REALIZED THAT WHILE I COULD HEAR VARIOUS COMS FROM THE APCH FACILITIES, I COULD NOT TALK TO THEM. SINCE RADIO CONTACT IS ESSENTIAL FOR OPERATING IN THE ADIZ, I ELECTED TO LAND IMMEDIATELY. DURING THE LNDG PHASE, THE XPONDER WAS STILL SET TO A DISCRETE ADIZ CODE, AND NOT 7600. THUS, IN MY OPINION, DURING THE LNDG PHASE, POTOMAC TRACON MAY HAVE THOUGHT THAT I WAS NOT IN COMPLIANCE WITH THE ADIZ PROCS. WHILE NO CONTACTS WERE MADE ON THEIR BEHALF, I FEEL AS THOUGH IN THE EVENT LIKE THIS TAKING PLACE AGAIN, IT WOULD BE MORE APPROPRIATE TO HAVE CODE 7600 IN THE XPONDER.
