There's really only 1 digi that can hear me and that I can hear and is about
35 miles away.  The digi isn't very active other than the wide3-3 beacons
the other digis farther up in wisconsin put out and many other mobile users
not in direct range of that digi.  They have good coverage in WI with most
every Digi having an IGate nearby so I have no idea why such long paths are
used.

All I intend on gating right now are NWS packets from the 2 area offices so
that when I'm out storm chasing I don't always have to rely on an internet
connection for watches and warnings.  I was down towards central Iowa
chasing when on my UI-View the watch boxes automatically appeared and I'd
like that coverage here also.  I would only need a WIDE1-1, and probably
hear it RF direct most of the time.

I'm also working on a balloon project with a school and looking at maybe
gating other balloon launch packets locally to demonstrate how it works to
some of the students.
