Those weren't random examples, those were packets I saw over the
weekend. Most were WIDE4, 5, or 6, but I have seen 8 and 9. I looked
a couple of calls I could remember up on findu. Here's a couple:
WinAPRS 2.4.7 -MOGRNSGF -247-<530>
These two are 400 and 275 miles, respectively, from my station. IMO
the first is definitely excessive and the second may or may not be,
depending on how much ARPS traffic you have in your area (I think it is
for our area and for his).

Yep, and that's why I asked about configuring a digi to drop those who
have that attitude.

Yep, and an IGate/digi another mile past that. Huntsville is pretty
well covered, as far as I can tell.

Not when I'm at home. I have a ~30 mile commute, and only a few
digipeaters have very limited coverage until I get over half way to
work. There are digis north, south, east, and west of Decatur but none
_in_ Decatur, and the coverage is not good. I don't know how to get
findu to draw a map around coordinates, but if you look around 34
32.810N 087 03.750W you'll see a hole. Try
I do have contact info for a couple of the local digipeater operators
and will talk to them before I put anything up.
Thanks again to all who responded; WA8LMF's essay was what I was
looking for on that subject. I'd still like to see a good book with
all this stuff in it. (:
