The XPNDR light on the ATD keeps blinking, just exactly like it is
seeing local replies!!!

Was your DME on? It will make the light go off, too.

Pulled the DME out of the plane years ago. Shouldn't have been any
intentional radiators in the plane (at least, not on). Now was there any
known high-power ground radiators in the area (nothing more than the
occasional phone tower). This is pretty much just open farmland. And it
doesn't normally happen here. [As opposed to plenty of other areas around
central Texas where the ATD will always get a false alarm.]
