Well, since practically everybody uses GPS, and radar coverage is
essentially nationwide now, making sure your VOR is accurate within a
couple of degrees every 30 days, and also keeping a detailed record of
that, seems a bit out of date. Kind of like making sure your buggy
whip is in good condition every 30 days.


Radar coverage does not extend nationwide at low altitudes. In fact I would
bet that 99% of the country does not have radar coverage below 1000' AGL.
This is where VOR accuracy really matters anyway.
