         Yes, if I show the digis I get the circle.  without the digis, I 
don't.  UI-ALOHA uses whatever packets UI-View32 sees and does not exclude, 
according to whatever exclusions are set up via a menu.

         Take a look at these -- the first is what I was seeing earlier 
without the digis, and the second includes the digis.  The difference is 
easy to see.

         What I'm starting to think, and this idea isn't fully developed 
yet, is that maybe we don't need to see the digis so often, and maybe we 
don't need to see them with such a path.  Or with ANY path, I'm still 
trying to develop this into something coherent!  <G>

         Gee, I never see that stuff here.  The most I ever see in Kansas 
are those few digis.  The path from there apparently goes way north of me 
through the digi at Des Moines.  There is no direct path from there to here.

         All I see in Colorado is usually W0WHE-4 and sometimes WB0JRG-7.
         NEVER see anything in Nevada, and only a couple of digis EVER show 
up in Utah, and they're rare.
         Arizona?  Sometimes I see the stuff the Motorola club has, but not 
usually.

         Of course, band enhancements change that a bit...
