PHGR is 4 digits, 7 digits if you count the letters PHG before the
numbers.  Pete pointed out that many folks have to tweek their PHGs to
make the circle match the real world coverage... and some users don't
understand we are talking about HAAT and not negative depth relative to
MSL (hihi).

So why don't we kill all these birds with one stone...  why don't we
list PHG as a range in nautical miles?  I can represent 999 miles in
three digits.  We'd need to also include a direction and let's say, a
percentage offset for the circle.  As an example...

R15999  (broken down would be Range 1*45degrees, 0.5*radius, 999 mile
radius) would draw a range circle that was 999 miles radius with it's
center offset NorthEast (1), and offset .5*999 miles.
