Thy this link. It allows you to position an aircraft in relation to two
Navaids (VOR or NDB) and play with the indicators.

In pursuit of a PPGL certificate (after many years of flying
ultralights) I have been going thru various glider flying books, study
guides, and the FAA knowledge test questions. In one version I have of
the FAA question list I see that a working knowledge of VOR navigation
is required to answer several test questions correctly. But not much
about it is discussed in the study guides.

I wonder if anyone here has recently taken the private pilot glider
knowledge exam, and if so are there questions in it about VOR
navigation, and other perhaps “obsolete” technology that I need to
learn.
