Steve, It is either the transmitter, antenna or the connection between the two. An avionics shop should be able to quickly locate which component is at fault. You can leave the transponder at the avionics shop (not the airplane) and, if you are in some non TFR controlled airspace, (B-veil or C) you should be able to call up ATC (phone or radio) and get non-transponder transit through the area.
