Nevertheless an aircaft that has a transponder is required by the regs
to have it operating, or does it? Do Reno area gliders have an LOA
that exempts them?

Independent of the legality (and, I assume, it is not strictly legal),
discussions with Reno ATC over the years indicate that they would rather
we have transponders and turn them off outside of the high traffic area,
then not have them at all...
