That's what it is, a solid blue circle with a thin ring around it.
Did you look at the .GIF file?

My list was a list of overlay symbols.  Since all digis should use
the overlayed DIGI symbol, it seemed pertinent.

No, when a WX station is also a digi, it should use the normal
"blue" circle, but then the circle should be Green instead of blue.
as shown on the .GIF image above.  This is a little tricky though
and it should  be elaborated:

If the WX symbol is in the alt table but no overlay then it should
just be a green WX symbol showing that it is both a WX station
and a high-site digi.  But if an overlay is applied, then it remains
blue because the assumption is that the modifier character has
something to do with its WX, not with its digi function.  For examle
we thought that there would be classes of WX stations:
C for Citizens WX
N for NWS calibrated sites
H for home stations
B for stations at balloon launch sites
or any other 26 such possibilties....

I like the star inside a box idea.  But I would leave the roof off of
as long as there is room for the overlay character to go and still
be readable...

Yes, its unfortunate, though understandable, that all APRS
clones chose to use static, unmodifyable ICONS for their
symbols instead of scaleable, pointable, colorable vector
graphics as originally intended.

Ill look at your set and see if I see any inconsistencies...
thanks for your work on them...
