Quite few years ago now and during my PPL, I was explained about QDMs&QDRs. What a confusing way to teach about a Radial. Anyway later someone showed me the light
and I have since, used radial and when I came across people trying to get their head around VORs and NDBs, I, this time showed the light by preaching the good word. RADIAL, RADIAL, RADIAL!!!! That's what it's called and that what it is.
