If you are aware of such gliders, then maybe a friendly talk with whoever signed their logbook is in order. If that doesn't resolve the problem, a call to the local FSDO might be required.

Perhaps someone should be taking a close look at your glider? :-)
The glider in the Minden midair had a transponder installed,
it wasn't legal, yet the glider still flew.

My understanding is that it was inoperable due to not yet tested, so legal, since it's not a required instrument.

Unless you put the antenna in your pants, there should be no problem with the radiation emitted by a transponder. Here's a good read on the subject. If you mount the antenna on the bottom of the fuselage behind the main wheel, it's more than far enough from your precious parts.

PS The electrical system in my glider is perfect.
